Key Figures

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.

Humans, the Short End of the Time Scale

The long-winded history of the Great Plains is recorded in the geological features we see today. The Precambrian shows itself in outcrops of the pink Town Mountain granite, the Packsaddle schist and Valley Springs gneiss. These rocks tell a story of massive chambers of boiling-hot magma being pushed to the surface to cool, and surrounding rocks being metamorphosed by intense heat and pressure. In the Paleozoic and later in the Cretaceous, ancient shallow seas covered the inner continent and produced carbon-rich rocks. Limestones, shales, and fossilized reefs are scattered throughout the Great Plains and nearby areas, evidence that the area was not always the ‘Great American Desert’. Decaying plant matter built up and compressed over time resulted in coveted coal deposits. When the waters retreated, the temperatures started going down, too.

Now, the Great Plains are dusted by a layer of younger sediments—sand and gravel and soil—eroded from the Rocky Mountains on the western border. These sediments help trap water underground in aquifers, supplying the region and its inhabitants. It is no surprise that pockets of water have been attracting all sorts of living beings for thousands of years, and early humans were no exception.

The common consensus among archaeologists is that humans began living on the Great Plains at least 11,000-11,500 years ago, based on carbon dating of various artifacts like bones, stone flakes and tools. This time overlaps with the last Ice Age, and the time of giant creatures like mammoths and saber-tooth cats (see Miocene and Mammoths). In 2005, a study took advantage of some broken mammoth bones that had been on display at the Denver Museum of Nature and Science for nearly 30 years. The bones appeared to have been broken by humans rather than by natural means, and were carbon dated at about 12,200 years old. Many scientists are drawn to the significance of discovering the oldest site with clear evidence of human habitation, and so research continues.

Humans have been fascinated by the challenges and opportunities offered by life on the Great Plains for a very long time, whether because of water and food resources, the hunt for gold and precious materials, agriculture, or an adventure. This curiosity is prominently realized in the mid-1800s, when Americans were surveying the Territories and some people thought that rain would follow the plow.
