High Strangeness At Hopkinsville


J Allen Hynek, PhD, professor of astronomy and a specialist in stellar evolution at Ohio State University, probably wasn’t thinking about a small town called Hopkinsville in the neighboring state of Kentucky as he sat down to dinner in the early evening of August 21, 1955...

Dr Hynek had no idea that a visitor from Pennsylvania, one Billy Ray Taylor, would be stepping outside at 7 PM to get a drink from a hand pump because the Suttons, his hosts, did not have running water inside their modest home in Kentucky’s backwoods not too many miles from Hopkinsville...

For his part, Billy Ray Taylor probably didn't know J Allen Hynek was a consultant to the United States Air Force investigation into Unidentified Flying Objects.  And he almost certainly had no premonition that Hynek would be credited with coining a term-- "high strangeness"-- many years later when he no longer worked with military men who were trying to figure out what people saw in the sky when they saw things that ought not be seen in the sky...

J Allen Hynek makes a cameo appearance in Steven Spielberg's
Close Encounters of the Third Kind
 
High Strangeness is a good way to describe what happened to Billy Ray Taylor and his hosts about an hour after the Pennsylvanian got his drink of water.  He told the others that he'd just seen a flying saucer in the western sky.  Its lights had all the colors of the rainbow.  The Suttons chuckled, amused by Billy Ray's vivid imagination, and told him he should recognize a shooting star when he saw one...

What happened next is well-known to any serious student of the UFO phenomena.  At roughly 8 PM, the Sutton hound began barking and howling and soon crawled under the house where he hid until the next morning.  Being good rural sorts, Billy Ray and Elmer "Lucky" Sutton decided to get a shotgun and a deer rifle to investigate the ruckus.  They stepped outside and promptly opened fire.  Moments later, the men rushed back inside, claiming they’d seen something floating in the air near the tree line...

The "something" was humanoid, roughly three feet tall.  It had huge ears that pointed up and spindly limbs that reminded the Suttons of a hospital patient with atrophied legs and arms.  Claw-like talons seemed to be the best way to describe the creature's hands.  It had a silvery glow.  Most disturbing to Billy Ray and Lucky was the fact it seemed to be impervious to bullets.  A shotgun blast would hit the critter and it would gracefully tumble backwards through the air in slow motion and then resume floating toward the house...


Biologist Ivan T Sanderson, who had a strong interest in
unusual phenomena, poses with a model of the Hopkinsville
Gremlin in an undated Polaroid photograph.
Eventually, the gremlin-- as the Suttons called it-- and several more like it reached the Sutton house, where (still floating in the air) they peered in through the windows and clambered on the roof, scaring the tarnation out of kids and adults alike.  Billy Ray and the Suttons fired at the creatures through the glass and walls for several hours.  Every bullet had the same effect: the gremlins floated away unharmed and then returned to be shot again so they could float away unharmed and then return...

Neighbors down the road heard gunshots from the Sutton place and wondered what in the world could be going on.  None called the sheriff, figuring it was the Sutton’s affair if they were shooting at someone…

After a couple hours, the goblins (a term often used by modern researchers) appeared to tire of the game and disappeared.  Billy Ray and Lucky and the rest of the household piled into the family car and burned asphalt to nearby Hopkinsville where they reported what had happened to Police Chief Russell Greenwell...

Greenwell and twenty other lawmen including Kentucky State Troopers investigated the Sutton home that night.  The chief and his officers didn't know what to make of the crazy tale they heard when the Suttons invaded his station.  But they knew a look of genuine terror when they saw it and they saw it in the eyes of every man, woman, and child who stood before them.  What made this troubling was that a State Trooper had radioed in a report of a strange object in the skies near Hopkinsville.  What made this more troubling was that the Sutton family enjoyed a good reputation in Christian County-- hardworking, devout and regular churchgoers, honest, and not inclined to sample moonshine...

What do we do with a case like the Hopkinsville Goblin Incident…

United States Air Force investigators opined the Suttons mistook a
Great Horned Owl for silver-clad "gremlins" floating in the air.
 
Do we ignore it?  Do we attempt a ludicrous explanation such as one offered by Major John Albert of the Air Force two years after the incident-- the gremlin was an escaped circus monkey painted in silver?  Do we nod sagely and agree with those who opine Billy Ray and the Suttons misidentified Great Horned Owls defending their nests?  This latter is perhaps more ridiculous than Albert's escaped monkey explanation.  Country folk know owls and educated fools when they see them...

Seven years before the Sutton incident, J Allen Hynek was, by his account, a skeptic when it came to UFOs.  He was a man with solid academic credentials and he'd been teaching at a major state university since 1936 with the exception of the World War II years when he worked as a civilian scientist for the Navy as one of the developers of a radio proximity fuze.  In 1948, newly hired as a part-time consultant to the Air Force's Project Sign, Hynek was confident he would learn people who saw flying saucers had misidentified known objects or were unreliable witnesses.  He considered the whole subject "utterly ridiculous"...
J Allen Hynek would become infamous in the early spring of
1966 for suggesting Michiganders were seeing "swamp gas"
and not flying saucers.
Dr Hynek attempted to debunk UFO sightings for many of his 21 years as a Project Sign and Project Bluebook consultant, writing he not only enjoyed finding rational explanations for extraordinary phenomena but also felt an unspoken pressure from the military to find the unusual was simply misunderstood and mundane.  In the mid-1960s, he would become infamous for explaining a series of sightings in Michigan as "swamp gas"...


The official attitude that everything about unidentified aerial phenomena could be easily explained away as misidentification of conventional objects began to trouble Hynek who basically initially believed the same thing... 

As a scientist, he had difficulties with his own willingness to jump to conclusions without a thorough analysis of the data.  His review of information available to him suggested that the subject of UFOs was more complex than he initially thought.  Another thing that bothered Hynek was that many reports coming across his desk were made by trained observers such as military pilots.  These were not men who were prone to jeopardizing careers by signing their names to a prank incident log...

Hynek would eventually found his own Center for UFO Studies in 1973.  His studies of the subject never led him to any definite conclusions but he increasingly placed a high value on the strangeness of some reports.  It is one thing to see an unknown light zip across the night sky in a straight line at a speed ten times greater than the fastest plane made by men.  But it is another thing if this object comes to an abrupt halt, changes shape, disappears, then reappears to resume a zigzag journey across the heavens...


Hopkinsville, site of the infamous
Gremlin attack, was also home to the
Sleeping Prophet, Edgar Cayce, said
by many to be a worker of miracles.
[Jacques Vallee, another scientist who has investigated the high strangeness of some UFO reports, originally supported the possibility of an extraterrestrial origin for some of these unusual aerial events.  His study of the phenomenon caused a shift in thinking for the co-developer of NASA's first computerized mapping of Mars.  He now suspects the UFO phenomenon is associated with a non-human consciousness that can manipulate time and space.  In Steven Spielberg's Close Encounters of the Third Kind, Vallee served as the model from the French researcher Lacombe who was played by noted film director Francois Truffaut.  J Allen Hynek also appears briefly in Spielberg's movie in a non-speaking role as the bearded pipe-smoking man who witnesses the alien disembarkation towards the end of the story.]

As for the Suttons, Chief Greenwell and the other lawmen accompanied them back to theirhome around midnight.  The police officers and troopers saw walls filled peppered with gunshot and broken windows.  Each witness was interviewed separately and told basically the same story.  Neighbors were tracked down and they told the cops they'd heard lots of gunshots from the Sutton place.  Late in the night, the police left, unsure of exactly how to report the incident, but convinced something strange had happened...

After the law had gone, a lone floating gremlin returned at around 4:30 AM to the small house between Kelly and Hopkinsville.  Billy Ray Taylor grabbed the shotgun, fired, and shattered one of the home's few unbroken windows as the little troublemaker playfully vanished...

 
The Sutton family's experience was not the only unsettling "contact"
between humans and small humanoids during the 1950s.  A little more
than two years after the Hopkinsville incident, a Brazilian farmer claimed
to have been forced into a sexual encounter with an alien female.

Will The Real Prince Of Darkness Please Stand Up

 
"Paradise Lost is one of those books which the reader admires and puts down, and forgets to take up again.  None ever wished it longer than it is."-- Samuel Johnson, Lives of the Most Eminent English Poets, Volume One: Milton, 1779

 
A few days ago, a hike to the road and mailbox brought an anonymous letter addressed to me in handwriting I didn't recognize.  The missive contained a vile little pamphlet alerting me to the fact that Satan gave Roman Catholicism and Islam and evolution to the world so mankind might be deceived and lured into eternal damnation.  This was a fact I hadn’t known and one which I still thankfully do not know...

John Milton's Paradise Lost
 

This venom spewed out in the name of a loving God bore the imprint of an outfit called Chick Publications which offers to send the reader a sample assortment of more titles for a mere $12.95.  The Southern Poverty Law Center considers the firm to be a band of hate mongers and it is hard to disagree with such an assessment after looking at even a single tract.  Page 8 of the pamphlet I received reminded me "Jesus hates Catholicism and calls her the Great Whore".  Additionally, it berates former President George W Bush for urging Americans to distinguish between deeds of terrorists claiming to act in the name of Allah and a faith deeply held by a billion people...


While Jack T Chick's cartoon collection is likely best used as a floor liner for the cage of a diarrheatic ape, he certainly isn't the first English language writer to pontificate on the Prince of Darkness and his misdeeds.  Nor will he be the last...


Paradise Lost, John Milton's epic poem exceeding 10,000 lines of blank verse, tells the story of a rebellion in Heaven against God led by Satan who, along with his followers, is cast down into Hell where he plots to corrupt Jehovah's newly formed Earth and lead our primeval parents Adam and Eve into death and sin by convincing them to eat of the fruit of the Tree of the Knowledge of Good and Evil...

Satan is cast from heaven in Gustave Dore's 1866 illustration
for Milton's Paradise Lost
 

Milton obviously told his story well since many people assume it reflects the Biblical tale of Eden although the poem bears little if any resemblance to the account to found in the Hebrew scriptures.  Genesis tells us in Chapter 3 the serpent who led Adam and Eve to open their eyes and be like divine beings in knowing good and evil was the "shrewdest of all the wild beasts the LORD GOD had made."  Here, the wily snake is a trickster not much different from those in other origin stories found elsewhere in the world...

 

[An identification of Serpent with Satan doesn't appear to have taken place in Judaism until the early part of the Common Era (CE) shared with Christianity.  A Hellenistic work, the Greek Apocalypse of Baruch, which may date to as early as 130 CE, is among the first works to link Eden’s snake to the darkest of angels.  Other scholars believe the earliest hint of such an identification occurs in The Wisdom of Solomon, dating to about two centuries earlier.  Others say the first clear merging of the two figures comes in The Apocalypse of Moses, likely penned in 1st Century CE.]


Satan makes very few appearances in Hebrew scripture.  He never does so as a force even remotely capable of challenging Yahweh's authority.  (Giving him power to do so would encroach on the sovereignty of God Who, in Isaiah 45: 7, clearly claims to form the light and create the darkness and to be author of peace and maker of evil.)...


In the 21st chapter of First Chronicles, Satan arises against Israel and incites David to conduct a census.  God becomes angered by the presumption that God's people can be numbered like cattle and sets pestilence upon the land, killing 70,000 men.  Still filled with wrath, God relents after David looks up to see "the angel of the LORD standing between heaven and earth with a drawn sword in his hand directed against Jerusalem" and begs the Almighty to direct vengeance against him and not the innocent people of Israel...

Emil Jannings as Mephisto in a 1926 film adaptation of the Faust legend
 

Readers familiar with the Bible may recall an older version of this story is to be found in the 24th chapter of Second Samuel.  But, here, it is God who prompts David to "go and number Israel and Judah."  David-- as in First Chronicles-- does the proper kingly thing and asks the Lord to punish him and not his people...


The difference in the two accounts may be explained by when each work was written.  We know the earliest possible date for First Chronicles would be 539 BCE based on the history it records and also that the book was likely put down on a scroll, give or take a decade, circa 300 BCE.  Samuel belongs to earlier times-- three centuries or more-- with its final story taking place during David's reign, or roughly a thousand before Jesus.  Attitudes about God's direct involvement in human misery were clearly evolving during the centuries between the tales told in the Chronicles and the penning of Samuel...   

William Blake: Satan smiting Job with boils, 1826

An unfortunate chap named Job has his own experience with ha-Satan, The Adversary, who presents himself to the Lord alongside other members of the celestial court one fine day. God asks if Satan has come across Job, "a blameless and upright man who fears God and shuns evil" in the course of his roaming across the earth.  The Adversary answers Job honors God because God constantly blesses Job, making him richer and more comfortable with each new day.  "But lay Your hand upon all that he has," Satan counsels the Lord, "and he will surely blaspheme You to Your face"...

 
Marc Chagall's 1960 depiction of the despair of Job


Thus began the tribulations of the righteous man named Job who eventually hears a Voice challenging him out of the whirlwind to gird up his loins like a man and answer where he was when the Lord laid the foundations of the earth or say he can dispatch the lightning on its missions...

 

[Job, incidentally, holds an important place in Judaism, Christianity, and Islam.  In the latter religion, he is considered a prophet and Islamic narratives about his misfortunes are broadly similar to the Biblical account.  Shaitan, aka Satan, plays a much more malevolent role in the Koran and Arabic folklore, however: after he overhears angels praise Ayyub as a righteous man, the Devil takes it upon himself to corrupt Ayyub and his wife.  Knowing the two will remain faithful despite any evil worked by Shaitan, Allah permits them to suffer temporarily.

Modern scholars believe Job's story took on its current form between the 6th and 4th Centuries before the Common Era.  Job was likely cobbled together from multiple sources, one of which may have been the product of an Edomite author.  Students of the book cite linguistic constructions and a general lack of Jewish "color" to support arguments the unknown writer lived somewhere south of the Dead Sea.  Other experts suspect early versions of Job's tale date back to to ancient Sumer, the city-state which flourished five thousand years ago in the area of current day Iraq.]

Earlier, we noted a gradual tendency to avoid directly attributing evil to God.  This may have been due to the growing regional influence of the teachings of a Persian prophet named Zoroaster who lived about six centuries before the Common Era.  A vegetarian who condemned animal sacrifices, Zoroaster taught a monotheistic faith in which Ahura Mazda, sole and Uncreated Creator of the universe, constantly battles Angra Mainyu, source of sin and evil and father of demons.  Angra Mainyu may be strong, Zoroaster said, but Ahura Mazda will ultimately defeat evil through the aid of good men...

light in Zoroastrian thought, attacks the cosmic bull in a carving at Persepolis
(photograph by Mary Loosemore, 2008)


As the new religion of Christianity took root, its chroniclers incorporated an encounter between Jesus and Satan into the Gospel stories.  The writers of Matthew, Mark, and Luke speak of the Temptation of Christ by the Devil as he fasts in the wilderness...

 

 
Understanding the nature of this encounter requires an understanding of the Gospels in which the story appears.  The briefest version is found in Mark, suspected by scholars of being the oldest of the four canonical Gospels.  Written in Greek shortly after the destruction of the Temple in Jerusalem by Roman legions, Mark seems to be the work of an unknown writer living in Syria.  It dates as early as 70 AD.  This is less than forty years after Jesus' execution-- and may contain accounts of his life that can be linked to a historian's Jesus vs a theologian's Jesus...


[Mark's narrative is a sparse account from the "this is what happened" school.  It does not open with an account of a miraculous Virgin Birth and concludes almost immediately after Jesus is raised from the dead and instructs his disciples to go forth into the world.  Satan appears only indirectly when the writer says the Holy Spirit drove Jesus into the desert for forty days after his baptism at the hand of John the Baptist.  In the desolation, Jesus finds himself tempted by Satan but no other details are provided.

These missing details show up in Matthew (probably written around 80 CE by a person of Jewish birth) and Luke (likely composed at around the same time as Matthew by the same person who recounted The Acts of the Apostles).  It is not likely either man knew the historical Jesus in the opinion of Biblical scholars. 

Matthew's intended audience appears to be Jewish (he doesn't take the time to explain customs referenced in his narrative, implying a belief his audience would be familiar with them) and we can assume his account of Satan coincides in some degree with the thinking of his readers.  During the Temptation episode, Matthew says, Satan presents himself to the Nazarene as an alternative god to Yahweh, offering Christ the kingdoms of the world if he would but fall to his knees before Satan.]

Duccio: The Temptation on the Mount, 1308
 

All three Gospels, we note, were written during a time of barely comprehensible change in the Jewish world, in the aftermath of a horror comparable to the Holocaust... 

The destruction of the Temple in 70 CE effectively ended the Jewish rebellion against Rome.  Caesar's armies were unable to claim total victory until Masada fell three years later but it was a hollow win for the Roman legions since the fortress' defenders chose suicide over submission to tyranny.  Flavius Josephus, a contemporary historian, tells us that over 1,000,000 people died during the siege of Jerusalem and 97,000 more were taken prisoner and enslaved.  Survivors scattered throughout the Mediterranean world...

Mystery religions and Gnosticism flourished in these places where the survivors found new homes...

We can, at a later date, look to the Mysteries for clues as to why the new Christian faith became a child alien to its Judaic heritage.  But it is the Gnostics and their notion of the Demiurge who can help us understand the transformation of Satan from a Counselor of God to the Lord of Hell...

 
Enemies of Freemasonry often assert its followers
worship darkness incarnated in the form of the
Baphomet, a scurrilous allegation repeated in this
late 19th Century illustration


In the early years of Christianity, there were a fair number of sects whose members saw the material world as evil and believed they could find salvation only through gnosis, the knowledge bringing mystical enlightenment and intuitive encounters with God.  Readers interested in studying the Gnostics in detail, be warned: many groups have cosmologies so complex and convoluted that it would probably be easier to wade through graduate texts on subatomic physics armed only with a fifth grade education than to try to quickly understand the world view of more than two or three Gnostic sects...

 

Gnostics also tended to see the material world as the work of a malevolent Demiurge, godlike but inferior to the true God who exists outside the world of stone and wood and flesh.  Most Gnostic sects did not identify Satan with the Demiurge but the Cathars, a 12th Century sect influenced by Gnosticism, believed the Creator God celebrated in the Jewish Bible was the Demiurge whom they called Satanael...

The Jewish Encyclopedia, 1906 edition, sums up early views about the Devil by noting the prologue of Job makes it clear The Adversary has no power of independent action.  And we can elaborate on this by saying, in addition to requiring God's permission to do his work, Satan doesn't have carte blanche in what he does.  He must act within limits specified by God...

Contact with the Persian dualism of Zoroaster and various Gnostic notions modified this early view both among common folk and the intellectual class.  (The 1906 JE offers an opinion that Zoroastrianism may have influenced the account of David's census in First Chronicles as well as a passage in Zechariah where Satan is The Adversary of the High Priest Joshua.)  By the 4th Century CE, the Palestinian Talmud had been compiled and it reflected evolving views about Satan found in the Apocrypha and New Testament.  To some of the rabbis, Satan was synonymous with both Samael (the Angel of Death) and that inclination in the heart of man to do evil...

Lest we forget, let us revisit Paradise Lost briefly.  Occasionally, when pressed to point to textual confirmation in the Bible itself of Milton's story of Satan and his rebellious horde being cast down from Heaven into Hell, devout Christians point to Isaiah 14:12-20.  A careful examination of the text suggests this is a warning to Nebuchadnezzar, King of Babylon, that his days are numbered... 

 
Composer Hector Berlioz musically retold the medieval German legend of
a scholar named Faust who sells his soul to darkness for the pleasures to
be known in this world.  In 1969, the principality of Monaco commemorated
Berlioz with a retelling of his version of the story in stamp form.


The confusion of a wicked king with an evil angel results from the poetic and beautiful language found throughout King James' Version of the Bible.  Literate men who lived in 17th Century England could not read Isaiah's mocking prophecy ("How art thou fallen from the heavens, O Lucifer, son of the morning") and fail to think of Milton's Satan who arrogantly thought to displace God...

In Genesis, we read of Adam and Eve and Serpent in Eden.  We contemplate the Lord God said, "It is not good for Man to be alone; I will make a fitting helper for him" (from the rib of Man as he slept) in the second chapter after creating Man, male and female, in God's image in the first chapter after saying "Let us make Man in our image, after our likeness".  And some of us wonder if these are not two different stories about creation...

We are not alone in such thoughts.  Many a rabbi and common man alike pondered the words of Moses' Torah before proffering a theory: Adam had two wives.  We know who his second spouse was: Ishshah, or Eve in modern English.  Folklore assigned Lilith as the name of Wife Number One...


In contemporary lingo, Lilith was one uppity woman.  She presumed to think that just because she was created in the image of God at the same time as Adam that she was also his equal!  Even worse, Lilith preferred to be "on top" when she and Adam had intercourse out of a theory she should enjoy sex as much as he did!  She tired of her unimaginative husband, the folktales say, and left him.  Then, one day, as she enjoyed the single woman's life outside the Gates of Eden by the shores of the Red Sea, she looked up and saw a handsome Devil out to raise a bit of hell on earth... 

Love at first sight, one supposes, since Lilith went on to become Mother of Demons...

Water In Texas: A Graphic Journey, East To West

“Average rainfall trends from east to west, with Orange in the Sabine Valley averaging about 59 inches per year and El Paso at the far western tip averaging about 8 inches.”  Andrew Sansom, Water In Texas: An Introduction, University of Texas Press, Austin, 2008

Questions about the availability of water dominate much of the political conversation in Texas these days.  At the same time that lawmakers smile at the increasing population of the state since this means more “clout” in Congress and in setting legislative agendas, they frown at the worrisome implications of more people in a vast land area where most of a population exceeding 20 million people is concentrated along and east of Interstate Highway 35.  Water is already scarce and it will become scarcer…


East of Houston

Ranch Country near San Antonio


West of San Angelo
 
Compounding the problem in the search for a state-wide solution to water related issues is the fact that Texas does become increasingly dry as one travels east to west.  This is not merely a function of lower precipitation levels but also the result of greater amounts of water lost to evaporation…

Let us take an imaginary journey from Houston to El Paso, with stops in San Antonio and San Angelo, comparing annual precipitation and water lost to evaporation along the way, noting the ever-increasing imbalance between the rain that falls to earth and the moisture that returns to the sky under the relentless Texas heat and wind…

Journey To The Desert's Edge, Part 10

Note: this is the tenth in a series of occasionally appearing entries focusing on deserts in general and the drylands of West Texas in particular
“At the foot of the Panhandle lies the vast western portion of Texas, an area of the state that epitomizes the isolation and beauty of the American desert.  From the edge of the metropolitan area of El Paso, the West Texas desert stretches over four hundred miles (640 km) into the heart of the state.”-- Gary Reyes, Texas, Mallard Press, New York, 1991


Defining deserts is a tricky endeavor and defining their boundaries can be even trickier business…

Readers of previous columns in this series about the dry country remember we have settled on a fairly simple definition for a desert-- an area where the potential water loss through evapotranspiration significantly (and consistently) exceeds that area’s precipitation.  Most scientists who study deserts agree on this definition…


The Chihuahuan Desert, broadly outlined in this map, is both
North America's largest and most biologically diverse desert.
It is also one of the continent's least explored wilderness areas.
We’ve also discussed the lack of universal scholarly agreement as to what “significantly exceeds” means.  In 1937, H C Trumble provided empirical answers to part of this dispute by demonstrating water need for a month exceeds water supply when computed evaporation is more than three times precipitation.  His work, cited over a decade later by C W Thornthwaite in a landmark analysis of climate, dealt only in facts and not in the nuances of language.  Thus, scholars continue to debate exactly what makes a desert a desert…

Does a region become a desert when this “three times precipitation” threshold is met-- or must the area be even more arid?  If it must be even drier, at what point is the land desert dry-- when computed evaporation is five times the precipitation, nine times the precipitation, twenty times?  Just what does “significantly exceeds” mean ...

One school of thought embraces a very wide stretch of country as desert and includes all of Wladimir Koeppen’s “B” series of dry climates.  Another school excludes those areas Koeppen defined as steppes but includes ones he called deserts.  (A problem with this approach is that Tucson, Arizona, and most of the Big Bend area of Texas would be among the places not considered deserts-- an omission that most visitors or residents of these areas might strenuously dispute.)… 

Near the author's home in western Tom Green County
Some scholars also say there are no true deserts in North America.  They limit deserts to exceedingly arid regions like the Sahara of northern Africa and the Atacama in Chile.  The latter may be the driest place on Earth.  Researchers believe parts of this vast desolation haven’t received measurable rainfall for four hundred years.  Average annual precipitation for the Atacama as a whole hovers around an estimated 0.004 inches.  Placing that figure in perspective, it could be somewhere around the year 2263 before we add a single inch to this desert’s sparse total…

A majority of laymen (and probably most scientists) say there are deserts in the United States.  There’s also general agreement four large areas-- the Mojave, the Sonoran, the Chihuahuan, and the Great Basin-- can be so designated.  Fixing their boundaries is a difficult and probably impossible task though…

Rough outlines of deserts have been established by studying plants native to a region.  The same can be said for other ecosystems such as grasslands or rain forests.  When Wladimir Koeppen first conceived the notion for developing a world-wide classification scheme, he drew upon both his training as a botanist and his childhood travels to botanically diverse regions through the Russian empire to create the broad outlines of his system. Later, as Peggy Larson commented in a study of the southwestern deserts, the botanist Forrest Shreve took this same understanding that plants define the natural character of an area and used it to decode the landscape of “the North American desert into four individual deserts… based on their distinctive vegetation”…

For more photographs of this fascinating desert shrub, visit the
Lady Bird Johnson Wildflower at the link provided in the text.
Shreve, who became director of Desert Investigations in 1928 for the Carnegie Institute, published his desert boundary outlines in a 1942 Botanical Review article.  Since then, subsequent researchers have either confirmed his descriptions, contracted the territory included in them, or expanded the areas he considered to be desert based on factors they consider relevant...

The largest disagreements over the boundaries of any desert focus on North America’s easternmost desert.  Mountain ranges basically limit the maximum possible boundaries for three of our four deserts.  But, for the Chihuahuan, those boundaries are ill-defined products of heat, wind, and potential evapotranspiration rates of dry west Texas plains.  Complicating the problem is the fact these boundaries more likely lie in places more resembling short grass prairies dotted with xeric shrubs than in the harsh landscapes known to us from cowboy movies...

Where those eastern boundaries might be can be seen on the map of Texas shown at the end of this essay…

First, we should explain what the map shows…

Colors are used to denote the presence of various plants in the map.  Counties shaded in brown contain populations of Agave lechuguilla and/or Flourensia cernua, populations documented on range maps developed and maintained by the United States Department of Agriculture (USDA) and/ or the Biota of North America Program (BONAP).  One should note that range maps are not always complete.  The reader will notice that Irion County, between Tom Green County and Reagan County, lacks a USDA or BONAP documented population of Flourensia cernua.  But such a population does exist...

Red counties have USDA or BONAP documented populations of Larrea tridentata, a widely distributed desert shrub, but lack similar records for either Agave lechuguilla or Flourensia cernua having been found inside the county.  Yellow means Condalia ericoides is present with no documented populations of the three other plant species.  Gray documents Tiquilia canescens...

Note: Readers who are interested in learning more about the plants briefly mentioned above and discussed in the following paragraphs are encouraged visit the Lady Bird Johnson Wildflower Center of Austin, Texas at https://www.wildflower.org/explore/.  The site contains descriptive information as well as photographs for more than 7000 native species.

Now, we need to explain what the map means…

Botanists like Shreve consider certain plants as unique to certain regions-- giant Saguaro cacti belong to the Sonoran Desert and the oddly shaped Joshua Tree yucca to the Mojave…

Unfortunately for those who love majestic desert beauty, two plants used to define the Chihuahuan don’t tower above arid landscapes as magnificently as do their cousins in the drylands of the west… 

But tarbush (Flourensia cernua) and lechuguilla (Agave lechuguilla) are like the Joshua Tree and the Saguaro in needing a hard land with poor soil, sporadic rains, and month after month of searing heat if they hope to flourish…


Saltbush, Atriplex canescens, seen here at the San Angelo State Park in Texas,
is one of the most widely distributed xeric shrubs in North America and is not
unique to any specific desert region.


Related to century plants but generally more compact in size, lechuguilla enjoys a bit of notoriety as the source of tequila. Sharp tipped leaves, slender and spiny enough to impale a man unlucky enough to fall on it, give the plant another common name-- shin dagger.  Like other agaves, it may take twenty-five years for lechuguilla to flower.  When it finally does, it shoots a spectacular plume of tiny blooms skyward from the center of the plant and then dies.  The life span of any lechuguilla is tied to the amount of rain it receives and the soil in which it lives-- the wetter the weather and the richer the soil, the sooner the plant dies…

Counties in red may lack documented populations of lechuguilla or tarbush but they do provide a home to creosote bush.  Known to scientists as Larrea tridentata, creosote bush often grows in association with tarbush in the desert country of Texas and New Mexico and southeastern Arizona.  Both are short spindly shrubs with tiny leaves.  Both exude odors highly reminiscent of petroleum-derived products.  Both thrive on alluvial soils derived from limestone.  But creosote bush can be found in more places than tarbush-- it and a tall wand-like plant with flaming red flowers known as ocotillo vie for the title of most widely distributed plant found in the “hot” deserts of North America…

(As the reader may suspect, creosote bush and ocotillo also grow, more often than not, in the brown counties where lechuguilla and tarbush can be found.  This association is strongest in the barren Trans-Pecos where almost every county is home to all four plant species.)

In the western Concho Valley of Texas, the association of these four species becomes sporadic.  Only lechuguilla has been found east of the San Angelo area.  Creosote bush makes limited appearances outside Reagan and Crockett counties and is difficult to find.  A Mesquite-Juniper-Creosote-Live Oak brush community can be found in southern Tom Green County but the numbers of Mesquite, Juniper, and Live Oak are far greater than the number of creosote bushes.  Texas Handbook Online articles anecdotally note the shrub's presence in the countryside near San Angelo, particularly around the hardscrabble country surrounding the Devil’s Courthouse Peak, known to most folk in the area as Devil’s Mountain, but one will find more Desert Sumac (Rhus microphylla) or White Brush (Aloysia gratissima) in a region that is also home to giant yuccas ... 


Javelina bush, Condalia ericoides, growing near the somewhat misnamed
Water Valley settlement in western Tom Green County.  Other photographs
of this plant, including some by the author, can be found at the Lady Bird
Johnson Wildflower Center website by visiting the link provided elsewhere in
this blog.
The spiny and twisted javelina bush can be found in Irion County, at one time part of Tom Green County.  Known to the botanical world as Condalia ericoides, javelina bush has a distribution much akin to that of tarbush and can be found growing in all counties west of the Pecos.  It is one of the many dry country species that the biologist Vernon Bailey noted as growing near San Angelo when he passed through the Concho Valley in May, 1899.  He described the area as a “genuinely arid region…with great stretches of smooth surfaces with only short grasses and little desert plants…(and) a scattered growth of small mesquites”…

One of those little desert plants mentioned by Bailey is Tiquilia canescens. Commonly known as “dog ear” due to the shape of its small, grayish leaves, this sub-shrub strays but very little outside desert regions.  Its presence, marked in gray on the map, is an indicator of land which receives erratic rainfall rapidly lost to wind and sun…

This map with color-shaded counties leaves us with much to ponder and topics to be explored in detail at a later date…

It suggests a large portion of Texas is exceptionally and naturally dry.  Detailed climate studies confirm that roughly 80% of the Lone Star State can be described as subhumid, semi-arid, or arid.  This implies very real challenges to both agricultural activities and human populations heavily dependent on water for survival, challenges highlighted and made more urgent by the proximity of large cities kissing the desert’s edge-- cities like Austin in Travis County and San Antonio in Bexar County…
