Exploring Fossil Butte National Monument
Fossil Butte National Monument is a fascinating site in southwestern Wyoming, located 15 miles west of Kemmerer. Established on October 23, 1972, it protects a rich collection of fossils from the Eocene Epoch, around 50 million years ago, within the Green River Formation. This monument is not just a scenic spot but a window into ancient life, showcasing well-preserved fossils of fish, alligators, bats, turtles, small horses, insects, and plants. These fossils reveal a subtropical freshwater basin that once existed in what is now a cold sagebrush desert.
The surrounding area, particularly Kemmerer, has its own historical significance, rooted in coal mining and railroad development. This article will explore the geological and paleontological history of the monument, its human history, and the context of the surrounding region, providing a comprehensive look at this unique site. These aren’t just any fossils; they are some of the best-preserved fossils in the world.
These preserved fossils tell stories of a time when this area was a lush, subtropical freshwater lake. It’s a journey to discover fossils and understand ancient environments.
Geological and Paleontological Insights
The Green River Formation, where Fossil Butte is located, formed during the Eocene Epoch as intermountain lakes filled with sediment. These lakes, including Fossil Lake, Lake Gosiute, and Lake Uinta, created varved sediments—annual layers of dark and light deposits—that record six million years of environmental history. The calm waters and fine sediment of Fossil Lake, with minimal scavengers, led to exceptional fossil preservation, making it one of the richest fossil sites globally.
Fossils at the monument include over 20 fish species, reptiles like alligators and turtles, birds such as parrots, and mammals like early bats and dog-sized horses. Insects and plants, including palms and ferns, are also preserved, painting a picture of a diverse subtropical ecosystem. This preservation allows scientists to study ancient climate changes and ecological interactions, offering unexpected details about how these organisms lived and interacted millions of years ago.
Green River Formation
The Green River Formation spans across Wyoming, Utah, and Colorado. It is known for its varved sediments, natural wonders and allows to discover fossils from a very important time. These layers provide a detailed record of environmental changes over six million years. Think of them as nature’s history book.
During the Eocene Epoch, the Rocky Mountains were uplifting. This process created intermountain basins that filled with water. Three major lakes formed: Fossil Lake, Lake Gosiute, and Lake Uinta.
Fossil Lake was the smallest. The calm waters, lack of scavengers, and fine sediment made perfect conditions for fossilization. Because of this Fossil Butte is a Lagerstätte—a sedimentary rock unit with extraordinary fossil content.
The sediments in Fossil Lake were composed of laminated limestone, mudstone, and volcanic ash. Each varve, or layer, represents one year of deposition. Scientists analyze the layers to understand climate and ecological changes of the river lake.

A Glimpse into the Past: Fossils of Fossil Butte National Monument
What kind of creatures roamed this ancient landscape? The fossil record at Fossil Butte National Monument is incredibly diverse. It paints a picture of a thriving ecosystem of the Eocene fossil lake.
- Fish: Over 20 species of fish fossils have been found. Knightia is among these fossils.
- Reptiles: Alligators, turtles, snakes, and lizards once lived here. These fossils indicate a warmer climate.
- Birds: Parrots and other bird species have been identified in the fossil record. This diversity adds to the picture of a subtropical environment.
- Mammals: Even early bats and small horses like Hyracotherium have been discovered. The fossils are incredibly detailed.
- Insects and Plants: Dragonflies, beetles, palms, and ferns are all part of the fossil record. These plant fossils further prove the warm, wet climate that once existed.
The exceptional preservation even allows for the study of soft tissues like skin and feathers. You can see how predator-prey relationships played out. This level of detail is rare and valuable to scientists.
Fossil Butte National Monument: More Than Just Fossils
Fossil Butte National Monument is just 15 miles from Kemmerer, Wyoming. Coal mining and railroad construction have shaped the area. This part of the country has a colorful story that is rich and diverse.
The Human Story
The human history of Fossil Butte began with coal mining. In 1843, explorer John C. Frémont discovered coal in the area. Later, in 1881, the Union Pacific Coal Company opened the first underground mine.
The town of Kemmerer was founded in 1897 by Patrick Quealy. He named it after financier Mahlon Kemmerer. Miners in the area soon began discovering fossils.
One early collector, Lee Craig, sold fossils from 1897 to 1937. These fossils were sold commercially, highlighting the paleontological value of the area. Eventually, scientists recognized the need to protect the area and the national monument protects all that is inside.
In 1972, Congress designated Fossil Butte a national monument. It was created to protect “outstanding paleontological sites and related geological phenomena.” A visitor center was also established to educate the public.
Inside, find over 300 fossils and interactive exhibits. Visitors to the national park unit get a sense of this amazing place.
The Town of Kemmerer
Kemmerer itself has a unique history. It was founded as an independent town, unlike many company towns. Individuals could buy land for coal and livestock ventures.
The town is also famous for being home to the first J.C. Penney store. James Cash Penney opened this store in 1902. From that beginning, a national chain emerged.
If you head into town, make sure you check out the J.C. Penney Company. It is a great opportunity to delve into the local history.
For decades the Kemmerer Coal Company was an energy sector. By 1950, the Kemmerer Coal Company was the world’s largest open pit mine.
