A Polar Bear (Ursus maritimus) Fossil in Breck Smith Cave, Kentucky?

September 16, 2012

Several old publications mention a polar bear fossil that was found circa 1916 in Breck Smith Cave which is 8 miles west of Lexington, Kentucky.  Apparently, 3 women who were exploring the cave discovered the bones, and they took them to an “authority” at the University of Kentucky. He identified them as polar bear.  Unfortunately, the specimen was never described in the scientific literature, and as far as I can determine, the ownership of this unique fossil has long been forgotten.  Because the presence of polar bears in northern Kentucky would have interesting ecological implications, I would like to locate the fossils and have a modern expert examine them.  If anyone knows where they are, please contact me.

Polar bear killing a seal.  If the fossil specimen from Breck Smith Cave was correctly identified, seals must have also been present in the Ohio and upper Mississippi Rivers during the Ice Age.  Walrus fossils have been excavated from 2 sites in Michigan.  As far as I know, those are  the closest pinniped fossils to Breck Smith Cave.

From the available information I don’t know for sure who the “authority” was that identified the polar bear fossil (or fossils), but I suspect it was Arthur Miller, head of the Kentucky University Geology Department from 1892-1925.  I strongly suspect he misidentified the specimen because the associated fossils imply a temperate environment.  Bones of raccoon, gray fox, woodchuck, wolf, bison, and man were found in the cave with the supposed polar bear fossil.  Today, polar bears are exclusively found in arctic marine environments.  I think it’s more likely the specimen is from a grizzly bear (Ursus arctos) or even a black bear (Ursus americanus).  Grizzly bears are closely related to polar bears and occasionally interbreed with them in the wild and in captivity.  A grizzly bear fossil was found at Welsh Cave as I related in my last week’s blog entry about the Kentucky Bluegrass Country.  However, there must have been a specific diagnostic feature for the scientist who identified the specimen to suggest the fossil specimen was from a polar bear.  Polar bears are almost entirely carnivorous, and their teeth are quite different from those of grizzly and black bears.  If he made the diagnosis based on teeth, he may have been correct.  There’s also the slight possibility that a man carried the polar bear fossil from the arctic to Kentucky.  Maybe he considered it a magic talisman of the great white bear.

Let’s assume the identification is correct, and it was not carried for a thousand miles by people traveling from the arctic to Kentucky.  How did polar bears, a species that depends largely on seals and whale carcasses, live in northern Kentucky?  Even during the Ice Age, northern Kentucky was not exactly polar bear country.  The Laurentide Glacier reached southeastern Ohio during the Last Glacial Maximum, but northern Kentucky was mostly prairie with fingers of boreal forests then.  Glacial advance during the Illinois Ice Age 100,000 years earlier than the most recent one was greater but still barely reached the Ohio River.  If polar bears did range into northern Kentucky during the Ice Ages, seals, their favored prey, must have been present on the Ohio and upper Mississippi Rivers.  Fossil hunters may want to look for seal specimens on the river bottoms here.

It’s not surprising that a scientist could have misidentified fossils from the Ursus genus.  Recent studies of the Ursus genome show a close relationship between black bears, grizzly bears, and polar bears.  (Grizzly bears and brown bears are one and the same species.) The first study of polar bear DNA determined they diverged from grizzly bears ~130,000 years ago.  Coincidentally and conveniently, this corresponds with the earliest known polar bear fossil which is from Norway and dates to ~130,000 BP.  A second study of polar bear DNA wasn’t as convenient–it suggested polar bears diverged from grizzly bears closer to ~600,000 years BP and as a species was much older than from what’s known in the fossil record.  Polar bears live in an environment where fossils are rarely found.  Most arctic fossils are deeply emerged in frigid waters, probably never to be found.  The most recent study of Ursus genetics looked at the whole genome, and it paints a much more complicated picture.  This study found that grizzly, black, and polar bears all diverged from a common ancestor between 4-5 million years ago.  This corresponds temporally with the beginning of the Pliocene when Ice Ages began occurring, causing continental changes in the environment and creating differentiating habitats for new species of bears.  Though black bears and grizzly bears diverged ~5 million years ago, the genetic evidence indicates these 2 separate species occasionally interbred until about 100,000 BP.  The genetic evidence also indicates that although grizzly bears and polar bears diverged as long ago as 5 million BP, these 2 species have periodically interbred in the past and they still do.

A second generation polar bear-grizzly bear hybrid.  A genome wide study suggests grizzly  and polar bears diverged about 5 million years ago but periodically interbreed.  The genome of brown bears living on the Alexander Islands in Alaska is made up of 5%-10% polar bear DNA.  Curiously, grizzly and black bears also diverged about 5 million years ago and periodically interbred until about 100,000 years BP.  Maybe that explains why Pleistocene black bears were as big as modern day grizzlies.

Polar bears probably interbreed with grizzly bears more frequently  during phases of global warming when their favorite habitat shrinks, and they come into contact more often.  Hybrids raised by grizzly mothers have a greater chance of survival because they learn to survive in a more varied habitat.  Middle Pleistocene polar bears were more genetically diverse than they are today, perhaps because the cycles between Ice Ages were shorter during this time period than they were in the Late Pleistocene.

John Lawson’s Voyage to Carolina (1700-1711)

July 27, 2012

I love reading accounts of the early explorers in America because they describe the natural environments before man modified (or in my opinion destroyed) them.  John Lawson was a well-to-do young man of 26 when he decided to explore and later settle in the Carolinas beginning in 1700.  He gives us the first literate account of the environments of the Carolinas in his book,  A New Voyage to the Carolinas, which was published in 1709.  Although his botanical descriptions don’t match those of William Bartram, who traveled through the south 70 years later, his account is fascinating nonetheless, and his quaint manner of language is interesting to decipher.

Route of John Lawson’s 1000 mile journey through North and South Carolina in 1700.

John Lawson’s journey in America began in Charleston, South Carolina shortly after Christmas.  In 1700 European colonization was restricted to a narrow band along the coast, and Charleston was the sole “metropolis.”.  Lawson took 6 Englishmen and 4 Indians on the journey with him.  They spent the first few nights at various islands along the coast including Bull’s Island where feral cattle and hogs abounded.  They spent another night with a Scotsman on Dix’s Island and ate oatmeal the Scot had scavenged from a Scotch shipwreck.  Despite the cool winter weather, mosquitoes plagued Lawson’s party at night.  While in the low country the party lived on venison, wild hogs, raccoons, fish, shellfish, waterfowl, and rice, the latter of which they purchased from nearby plantations.  They left the coast in a canoe and went inland for miles through uninhabited cypress swamp til they came into contact with Indians burning a canebrake.  Lawson related how the hollow bamboo stems exploded after ignition.

As we went up the river, we heard a great noise, as if two parties were engaged against each other, seeming exactly like small shot.  When we approached nearer the place, we found it to be some Sewee Indians firing the Cane Swamps, which drives out the Game, then taking their particular stands, kill great quantities of both bear, deer, turkies, and what wild creatures the parts afford.”

They continued their journey through cypress swamps that were in flood that time of year.  All the trees in 1 swamp had been felled by a hurricane, and they had a hard time navigating between the fallen giants.  During the journey they only slept on the ground when they had no alternative.  Usually, they could find a hunter’s cabin or an Indian town.  The hunter’s cabins were often unoccupied but well stocked with food.  As was the custom then, they’d leave beads and trinkets in exchange for food–a kind of honor system.  A typical  cabin pantry stored red beans, dried corn, dried peaches, and chinkapins–much healthier food than can be found in a McDonalds or any other fast food dump adjacent to our modern highways.  Indian towns were spaced about 20-30 miles, or a day’s journey, apart with nothing but wilderness in between.  At this particular time in history, all the Indians they met were friendly, though some tribes had a bad habit of pilfering Lawson’s party’s belongings.  One of Lawson’s comrades got robbed by an Indian whore on one occasion.  She stole his moccasins while he was sleeping after the party paid a fortune just so this 1 guy could get laid.

Upon reaching the piedmont region Lawson noted that his party could travel a whole day without seeing a single pine tree.  This region then was mostly an oak forest–a contrast from the second growth woods found in the Carolina piedmont today where pine is a dominant species.  The oak forests supported huge flocks of turkies.  Lawson saw 1 flock numbering over 500 birds.  At this point they ran short of bread and salt, and the only thing they had to eat was turkey.  They became so tired of eating turkey that 1 of the Indian guides shot and ate a skunk for variety.  Lawson also witnessed the legendary passenger pigeon and gives the following account.

In the mean time we went to shoot pigeons, which were so numerous in these parts, that you might see many millions in a flock; they sometimes split off the Limbs of stout Oaks, and other trees, upon which they roost o’nights.  You may find several Indian towns, of not above 17 houses, that have more than 100 Gallons of Pigeons Oil, or Fat; they using it with Pulse, or Bread, as we do butter, and making the Ground as white as a sheet with their Dung.  The Indians take a light, and go among them at Night, and bring away some thousands, killing them with long Poles, as they roost in the Trees.  At this time of the Year, the Flocks, as they pass by, in great measure, obstruct the light of the day.”

His noisy party kept away most predators but he does give this account of an encounter with a cougar (what he erroneously refers to as a tiger).

As we were on our road this morning, our Indian shot at a Tyger, that cross’d our Way, he being a great distance from us.  I believe he did him no harm, because he sat on his Breech afterwards, and look’d upon us.  I suppose he expected to have had a Spaniel Bitch, that I had with me,  for his breakfast, who run towards him, but Midway stopt her Career, and came sneaking back to us with her Tail betwixt her legs.”

After the journey was completed, Lawson settled in a cabin near the Neus River and worked as a surveyor when he wasn’t farming, and he founded 2 towns–Bath and New Bern.  He recounts an interesting experience with an alligator that took up residence under his first cabin.

I was pretty much frightened with one of these once; which happened thus: I had built a house about a half a mile from an Indian town, on the Fork of the Neus River, where I dwelt by myself, excepting a young Indian fellow, and a Bull-dog, that I had along with me.  I had not then been so long a Sojourner in America, as to be throughly acquainted with this Creature.  One of them had got his Nest directly under my House, which stood on high Land, and by a Creek-side, in whose banks his Entring-place was, his Den reaching the Ground directly on which my house stood, I was sitting alone by the Fire-side (about nine a Clock at Night, some time in March) the Indian fellow being gone to the Town, to see his Relations; so that there was no body in the House, but my self and my Dog; when all of a sudden, this ill-favoured Neighbor of mine, set up such a Roaring, that he made the House shake about my Ears, and so continued, like a Bittern, (but a hundred times louder, if possible) for four or five times.  The Dog stared, as if he was frightened out of his Senses; nor indeed, could I imagine what it was , having never heard one of them before.  Immediately again I had another Lesson; and so a third.  Being at the time amongst none but Savages, I began to suspect, they were working some Piece of conjuration under my house, to get away my Goods; not but that, at another time, I have as little Faith in their, or any others working miracles, by diabolic means as any person living.  At last my man came in, to whom when I had told the Story, he laugh’d at me, and presently undeceived me, by telling me what it was that made that Noise.”

He also had lots of experiences with black bears while living in the North Carolina low country.

The bears here are very common, though not so large as in Greenland, and the more Northern countries of Russia.  The Flesh of the Beast is very good and nourishing, and not inferior to the best Pork in Taste.  It stands betwixt Beef and Pork, and the young Cubs are a dish for the greatest epicure living.  I prefer their flesh before any Beef, Veal, Pork, or Mutton; and they look as well as they eat, their fat being as white as snow and the sweetest of any Creature’s in he World.  If a Man drink a Quart thereof melted, it never will rise in his Stomach.  We prefer it above all things, to fry Fish and other things in.  Those that are strangers to it, may judge otherwise; But I who have eaten a Great Deal of Bears Flesh in my Life-time (since my being an Inhabitant of America) do think it equalizes, if not excels any Meat I ever eat in Europe.  The Bacon made thereof is extraordinary meat; but it must be well saved, otherwise it will rust.  This Creature feeds upon all sorts of Wild Fruits.  When Herrings run, which is in March, the Flesh of such of those Bears as eat thereof, is nought, all that Season, and eats filthily.  Neither is it good, when he feeds on Gum-berries, as I intimated before.  They are great Devourers of Acorns, and oftentimes , meet the swine of the woods, which they kill and eat, especially when they are hungry, and can find no other food.  Now and then they get into the fields of Indian Corn or mais, where they make sad Havock, spoiling corn ten times as much as they eat.  The Potatoes of the Country are so agreeable to them, that they never fail to sweep ’em all clean, if they chance to come in their way.  They are seemingly a clumsy Creature, yet are very nimble in running up Trees, and traversing every Limb thereof.  When they come down, they run Tail foremost.  They sit by the Creek-sides, (which are very narrow) where the fish run in; and there they take them up as fast as it’s possible they can dip their paws into the Water.”

By herring, Lawson meant shad which is in the herring family.  He also wrote a long paragraph about hunting bears and the uses of bear’s oil.  Today, I don’t think there are any bears in the Carolina low country.

Lawson enjoyed an idyllic life of fishing, hunting, and farming while he lived in the North Carolina low country.  Like the majority of people living in the days prior to grocery stores, his life focused upon food production.  He grew corn, wheat, and vegetables, and he had a successful fruit orchard.  Unlike most fruits, peaches produce true to seed–the offspring resemble the quality of the parent.  Peaches were so widespread among the Indians that Lawson mistakenly believed they were a native fruit.  The Indians obtained peaches from the Spanish as early as 1550, and it quickly became an important food they ate fresh, dried, stewed, and in bread. Most, if not all, of the varieties Lawson grew came from seed he got from the Indians.  One variety was large and luscious.  Lawson called it a vinegar peach because he made vinegar from the fermented fruit.  He also had a tree that produced yellow freestone nectarines.  He claimed this tree never produced less than 15-20 bushels of fruit every year.  This is surprising considering he only farmed for about a decade and the tree must have been young.  He also claimed his peach trees began producing when they were as young as 3 years old.  Lawson’s vinyard consisted of native grapes, but he did have to import apple scions because all good cultivated apples are mutants.  Cider was an important drink and a substitute for beer which was considered essential for civilized life then.  His list of apple varieties includes rare antique types and some that are probably extinct.  He planted a 200 foot row of native strawberries, and like Bartram, he reported seeing wild strawberry fields of miles in extent. (See https://markgelbart.wordpress.com/2011/04/)

John Lawson is the sole source of information for many of the Indian tribes who inhabited the Carolinas.  Most of these tribes suffered extinction during the 18th century.  Lawson estimated the population of Indians in the Carolinas decreased by 85% between 1650-1700, explaining why wilderness was reclaiming so much land.  Smallpox and alcohol addiction caused the decline.  The Indian words for rum (the chief spirit they imbibed) was sick or poison, yet they couldn’t control their addiction.  Indians evolved in isolation from these 2 scourges, and they had little resistance.  Smallpox occasionally annihilated whole Indian towns.

I was surprised to learn some Indians that bring to mind the far west lived in the Carolinas.  Most of the tribes were Sioux.  Lawson even met some Flatheads who made their skulls flat by fastening a board to their infants’ heads.

Most Indian culinary practices revolted Lawson.  They cooked most game without removing the entrails.  A favorite Indian dish was deer fawn, removed from a dead pregnant deer and cooked in the natural placental bag.  However, Lawson did praise 1 particular Indian cook who repeatedly washed her hands before cooking and could make white bread.  Other Indian women ladled out stew with their bare hands even though they possessed wooden ladles.  Red beans were an Indian favorite, and Lawson provides an amusing account of its effects.

The small red pease is very common with them, and they eat a great deal of that and other sorts boil’d with their Meat, or eaten with Bears Fat, which Food makes them break Wind backwards, which the Men frequently do, and laugh heartily at it, it being accounted no ill Manners amongst the Indians.  Yet the Women are more modest, than to follow that ill Custom.”

Lawson held liberal views on Indians, so it’s a shame they captured, tortured, and killed him in 1711.  The stupid, sadistic brutes tied him to a stake, stuck wooden splinters all over his body, and set him on fire.  Lawson never married his sweetheart, Hannah Smith, but she bore him a daughter.  He left all his land to them in his will.

Artist’s depiction of the Tuscarora Indians capturing Lawson who was surveying land up the Neuse River.  He must have known the Indians were unpredictable and his job was hazardous because he wrote a will.   They let his partner go to spread the word and scare the settlers.  It was an act of terrorism that ultimately failed.  A war between the settlers and the Tuscarora Indians broke out shortly after they burned Lawson alive, and the Indians were defeated.

Gatlinburg, Tennessee–A Tale of a Tourist Trap Nightmare

June 20, 2010

I’m taking a break this week from my usual essays about Pleistocene Georgia to write a travelogue of a vacation my family forced upon me.  For my daughter’s 15th birthday my wife promised her a trip to Gatlinburg, Tennessee, a crowded tourist trap, bordering the north end of the Great Smoky Mountains National Park, which is itself an overhyped haven for wildlife.

Gatlinburg, Tennessee

The sidewalks are jammed with tourists from early morning till midnight, and they come from all over the world, including Ohio, Louisiana, Iowa, Florida, Texas, Missouri, Japan, and Germany.  Little shops and stores, like cigars crammed inside a tin can, stand in line on both sides of the confusing winding streets, beckoning the tourists to throw money their way.  There’s a Ben and Jerry’s Ice Cream Store, a Guinness Book of World Records Museum, a wax museum, a celebrity car museum, a hat and cowboy boot outlet, a country western bar, pancake houses and barbecue restaurants, a McDonalds, and untold other high, low, and middle end stores.  All this exists but with precious little parking.   There are no alleys in between the stores and no parking lots in front or to the sides of the businesses.  We found a parking lot in back of one museum that cost us $10.  My wife is disabled and I didn’t want to have to wheel her chair across town.  Gatlinburg’s not that big–I recommend (if tourist traps are your cup of tea) to hike downtown from your motel, or you can take one of the trolleys.  The streets are interspersed with rights of way for walking tourists, but out-of-town motorists don’t realize this, creating a dangerous hazard.  Other motorists disregarded the pedestrian rights of way, until they saw me stopping.

My daughter chose to throw our money away at the Ripley’s Believe it or Not Museum.

Ripley’s Believe It or Not Museum

I found this freak show rather lame and outdated, but I guess it’s ok for kids.  There’s nothing here surprising to a person well versed in science and history.

This is a hairball from a pig.  The poor animal must have coughed its lungs up to get this out.

This is a photo of me next to a replica of Robert Wadlow, the tallest man to ever live.  In a boxing match between us it would’ve been hard for me to land punches above the belt.

This poster of spiderman is made out of real spider webs.  Amazing!

This is a medieval chastity belt.  I bet men found a way to overcome this.  Where there’s a will, there’s a way.

Mark Gelbart Eats an Eyeball–Believe it…or Not

We ate supper one night at the Smoky Mountain Trout House, an overpriced tourist trap restaurant.  They serve trout 13 different ways.  The sides were nothing special–frozen crinkle cut french fries, the driest hushpuppies I ever ate, and bottled salad dressing.  The trout was good–I wolfed down a whole crispy fried one.  This was the first time I’d ever eaten a fish with the head left on.  I made Andrew Zimmern of the Travel Channel series Bizarre Foods proud when I dared to eat a fish’s eyeball.  It tasted strong, much fishier than the flesh, and I could feel the solid texture of the lens on my tongue.  I didn’t eat the other eyeball and don’t recommend eating them, unless starvation is imminent.

We ate lunch at the Flying Pig Smokehouse.  The prices here were more family friendly, and the barbecue genuine.  The apple cinnamon barbecue sauce went well with smoky pork.

Great Smoky Mountains National Park

I highly recommend this park for those interested in botany.  Situated as it is in the middle of eastern North America and with varying elevations, plant species diversity is high.  There are plants that prefer warm climate growing next to species with cold climate affinities, much like what grew further south in Georgia during the Ice Age.  I found hemlock, white pine, loblolly pine, white oak, chestnut oak, northern red oak, beech, birch, elm, tulip, red maple, box elder, buckeye, sweetgum, sycamore, hickory, bigleaf magnolia, and black walnut.  The large numbers of black walnut within the park boundaries surprised me.  This tree’s wood is prized by furniture makers.  It’s rare outside the park, though it formerly was a common species of our eastern deciduous forest.  Rhodadendron was common in the understory.

This is the view from Newfound Gap.  The mountains are literally smoking.

Meigs Falls

Rhodadendron in the center of the photo.

This is a potential bear den next to the Appalachian trail.  When large mature trees fall, the roots rip up caverns, making it easy for bears and other critters to dig deeper tunnels.  This part of the trail was busy and noisy.  We were sandwiched between a motorcycle convention in the parking lot and a hiker playing loud music.

I do not recommend Great Smoky Mountains National Park for tourists interested in wildlife viewing.  By far the most common large mammal species in the park is Homo sapiens–the park is badly overcrowded.  The main highway #441 that bisects the park has bumper-to-bumper traffic.  I even got stuck in a traffic jam.  Supposedly, the park holds 6,000 white tail deer, 1600 black bear, 600 wild boar, and 100 elk.  The only mammals I saw were an estimated 40,000 people and one gray squirrel–a bitter disappointment.  Supposedly, 200 species of birds reside in the park.  I saw 5, and they were species commonly seen in Augusta, Georgia where I live.

95% of the park is a closed canopy forest; the balance is meadow.  Some of the forested area is old growth.  Large mammal populations are low in old growth forests, and what little lives there is hidden in the trees.  No timbering is allowed so mast-producing trees, such as oaks,  are being shaded out by less productive trees.  Coupled with the loss of the chestnuts to the blight in the last century, this means there is little food available for large mammals.  Moreover, most of the areas in the park that are favorable for wildlife viewing were closed. Cades Cove, Roaring Fork, and Clingman’s Dome were all closed either for maintenance or due to rock slides.  Cataloochee Valley, on the eastern side of the park where the elk were re-introduced, is remote and difficult to access.  It’s at the end of a long, winding, unpaved road that’s steep and has a speed limit of 5 mph.  Because my wife’s disabled, I was nervous about continuing on this road.  If our car broke down, it would’ve been a disaster because she couldn’t walk back to civilization.  So I turned back.

I didn’t even see any interesting small mammals.  Red squirrels, also known as chickarees, inhabit the park as well as chipmunks and woodchucks.  None of these species live near Augusta, but alas I didn’t see them here either.

I did see lots of butterflies, especially eastern tiger swallowtails.  Their larvae feed on many of the tree species so common here.  I also saw two different kinds of butterflies from the Pieridae family.

The museum at the park welcome center had many fine stuffed specimens.  The museum affords about the only opportunity for a visitor ot see animals in the park.

I did catch a whiff of a nearby skunk at Newfound Gap.  It didn’t smell as bad as our hotel room which I nicknamed the Armpit Motel.

This is a tulip tree trunk.  Large, mature tulip trees are a dominant tree in the park.  None I saw approached this is circumference.  Most people don’t realize that much of the original forest in this area was leveled by 1910.   The forest now consists of second growth.

This is the biggest bald faced hornets next I’ve ever seen.  They’re a marvel of insect engineering.

Supposedly, this is a trout stream.  The waters are clear but I saw no fish, turtles, frogs, or fish-eating birds.  Don’t expect to catch trout here.  The only trout left in the area are grown on fish farms.

Admittedly, I’m a cynic.  I suspected the park administration exaggerated mammal population estimates to encourage tourism.  So to prove to myself that animals actually live in the park, I looked for tourist videos of wildlife in the park on youtube as evidence that they weren’t just making these figures up.   I don’t have direct links but do a search at www.youtube.com for “Bear breaks into car at Clingman’s Dome,” “Cades Cove black bear,” and “Elk in the Cataloochee Valley.”  Note how incredibly ignorant some of the tourists act around bears.  The footage of bears tearing up logs while looking for termites, and another of one digging up a yellow jacket nest is interesting.  The video of a bull elk bugling, while the rest of the herd rests behind a flock of turkeys is the kind of scene I had hoped to see.

Overall, I think the park is poorly managed and underfunded.  The current ratio of closed canopy forest to meadow limits quality wildlife habitat and viewing.  Selective tree cutting, as practiced by native Americans, would improve both.  Bison, wild horses, cougars, and wolves should be re-introduced.
