Ferdinand Vandeveer Hayden

The settlement of the Great Plains would never have happened so quickly, if not for a few key figures. Among them was Ferdinand Hayden, a theologist and surgeon by training, but a naturalist and geologist at heart.

Hayden was born in Massachusetts, but a troubled childhood—an alcoholic father and an abandoning mother who were unmarried—led him to be raised by his aunt and uncle in Ohio. Eventually, he made it to Oberlin College and attained a degree in theological studies, and later to Albany Medical College, where he received his medical degree. In Albany, however, he also met a number of aspiring paleontologists, such as James Hall and F. B. Meek. These two encouraged him to reach out to others, and to go out west and explore. At this time, his field work was focused around South Dakota and the Missouri River.

Hayden began publishing geologic papers with Meek, as well as collecting vast collection of fossil and archaeological specimens. Together, he and Meek are credited with some big finds: the first soft-shelled turtle fossil in America, and the first dinosaur remains. That’s not all. Hayden also gathered fish, shells, plants, mammoth and mastodon teeth, mammal bones, and more. On the human side, he found axes, pottery, flint shards, and mining tools. The Smithsonian Institute was quite intrigued with these artifacts, and unofficially recruited him to help them expand their own collection. Hayden became part of the Megatherium Club with a few other gentleman scientists and collected thousands of specimens for the Smithsonian.

After a few years as a surgeon for the Union army during the Civil War, Hayden went back to his geology. He headed a party that discovered and surveyed the vast coal beds of Colorado and Wyoming, making news all the way across the pond in London. Hayden then went on to survey Iowa and Nebraska, Montana, Missouri, New Mexico, and Wyoming. His reputation as a geologist grew so much that his funding from the government grew from $5,000 to $75,000 a year. Hayden was even considered for the first director of the newly formed U.S. Geological Survey—though he didn’t get the job.

While not an active proponent of rain follows the plow, Hayden’s exploration did lead him to believe that the planting of trees in the Great Plains would be the key in the settlement and agricultural prosperity of the region. He had seen how the addition of trees might have increased rainfall in other regions and was ready to extend that idea to his beloved Great American Desert.

Miocene and Mammoths

Ever wonder what it’s like to meet a mammoth? It was possible—only a few tens of thousands of years ago on the Great Plains. We call this epoch in time the Pleistocene, spanning from 2.6 million to 11,700 years ago. In the span of geologic time, this is a miniscule segment in the history of Earth. The world was in the middle of an extreme ice age, and North America was almost in the same position we see it now. North America was also host to the largest ice sheet at the time: the Laurentide ice sheet, a forceful tool that carved and shaped the landscape as it spread and flowed.

The Pleistocene is famous for its fauna, including Smilodon, the saber-toothed cat that was 30 percent bigger than a modern African Lion. The Smilodon is one of the most extraordinary cats to have ever lived, thanks to its incredible musculature, jaw strength, and extra-long canine teeth. Paramylodon, the cousin of the South American Megatherium (which became the namesake of a research club in the 1870s—look out for this post!), was a giant ground sloth. Unlike today’s sloths, they walked on the ground on feet sporting claws 18 centimeters long and lived and reproduced in caves. Glyptodons were a weird animal that looked like a combination of an armadillo and a tortoise. It had a six-foot long tail and possibly an elephant-like trunk. Animators made use of these quirky creatures in their film, Ice Age.

These, among other animals of the Pleistocene, are not only found in the fossil record of the Great Plains, but also in the unusually diverse La Brea tar pits. Thousands of excellently preserved specimens have been found in the gooey oil-tar underneath Los Angeles, California. After a few animals got stuck, their plight attracted predators interested in an easy meal. Some of the predators got stuck themselves, bringing in even more critters, creating a cycle. As a result, the tar pits have provided a snapshot of life in the Pleistocene, life that could be seen not just in (not so) sunny California, but across the continent.

Even more well-known are mammoths—some of the largest mammals ever walking the Earth. In the cold, harsh environment of the ice age, mammoths found refuge in a stretch of grasslands near the Sierra Nevada Mountains. Columbian mammoth remains have been found near ancient equine, bison, and sheep remains in the Upper Missouri Basin, the Rocky Mountains, the Yellowstone Basin and more. Basically, if there was vegetation available for eating, mammoths lived there. Some studies have even found mammoth limb bones showing evidence of human modification—giving light to the claim that early humans shared a world with these giant animals.
