#Lookback: Fremont County 50,000 Years Ago

A County 10 series in partnership with the Fremont County Museum System
where we take a #Lookback at the stories and history of our community and
presented by Mick Pryor, Financial Advisor with Edward Jones.

For the next few weeks, a recently discovered comet, C/2022 E3 (ZTF), is traversing the skies about Earth, appearing as a green smudge through binoculars. The last time the comet visited was 50,000 years ago, above a world both very different and very similar to the one we experience today.


While the comet passed in the middle of the last Ice Age, temperatures were rather mild. The Wind River Range and Yellowstone area were covered in glaciers, but the lower elevations may have been thawed out in the period. Geologically, much of the lower elevations in Fremont Count were the same then as they are today, only the mountains above being carved deeper by the glaciers covering them. A wide variety of large mammals roamed Wyoming throughout the last Ice Age. Natural Trap Cave, near Lovell, has a small, easily hidden opening at the top of it and an 85-foot drop to the bottom, meaning any animal that fell in would be killed instantly. Many of the mammals that fell into the cave and likely lived in Fremont County are familiar to us today, including weasels, martens, and wolverines alongside bigger animals like pronghorn antelope, deer, bighorn sheep, and bison. However, several mammals that no longer natively exist in North America, like musk oxen and horses, wandered the area through the Ice Age.


Many of the animals that walked Fremont County under the comet, however, are unfamiliar today. Species of camels, bigger than those living today, grazed on leaves, small plants, fruit, and grass. Dire wolves, with powerful jaws, hunted and scavenged alongside grey wolves and coyotes. Also hunting throughout the region were American lions, perhaps in smaller groups than modern African lions and with smaller manes. American cheetahs, evolved from the same ancestor as cougars, sped around the landscape in a similar way to modern cheetahs. The giant short-faced bear walked on long legs, and while less heavily built than today’s bears, it dwarfed grizzly bears by over a foot with a feline face, teeth
made for eating meat. One of several mammoth species also traversed the County area, potentially the world’s largest, the Columbian mammoth, whose shoulders rose to 12 feet high and whose tusks extended up to 13 feet long, covered in only a thin layer of hair.
