In the ridges of southwest Wyoming are some of the best-preserved fossils in the world. They tell the story of ancient life in a warm, wet environment in and around a freshwater lake. Stingrays swam in the lake. Turtles basked in the sun. Leaves rustled in the breeze while early horses darted between the trunks. We reveal more of the past with each fossil found.
No entrance fee.
Visitors may enter the park any day sunrise to sunset, but visitor services and motor vehicle access vary throughout the year. Camping is not available.
Hours are reported by the park — verify before you go.

When the climate changes enough, the vegetation communities growing in any given place will also change. Under an expanded bimodal climate zone, some plant communities in western national parks are more likely to change than others. National Park Service ecologists and partners investigated the future conditions that may force some of this change. Having this information can help park managers decide whether to resist, direct, or accept the change.
The Cenozoic Era (66 million years ago [MYA] through today) is the "Age of Mammals." North America’s characteristic landscapes began to develop during the Cenozoic. Birds and mammals rose in prominence after the extinction of giant reptiles. Common Cenozoic fossils include cat-like carnivores and early horses, as well as ice age woolly mammoths.
Across the US, changes in water availability are altering which plants grow where. These changes are evident at a broad scale. But not all areas experience the same climate in the same way, even within the boundaries of a single national park. A new dataset gives park managers a valuable tool for understanding why vegetation has changed and how it might change in the future under different climate-change scenarios.
Crocodylomorphs, including crocodylians and their extinct relatives, are known from body and trace fossils found in more than a dozen units of the National Park Service. The records range in age from the Late Triassic to the Pleistocene and include type specimens for five species, among them the giant Deinosuchus riograndensis from the Cretaceous of Big Bend National Park.

Pollinators play a crucial role in national park ecosystems and beyond. In the national parks, species inventories help managers know which pollinators are present, and in what abundance, to better understand the state of park ecosystems and make decisions about how to manage them. From 2024 to 2026, 17 parks across the country will be surveyed for bees and butterflies.
Invasive exotic plants are one of the most significant threats to natural resources in the national parks today. To provide early warning of weed invasions, the Northern Colorado Plateau Network monitors target plants in park areas where they are likely to first establish: along roads, trails, and waterways.
