Historical & Ecological Origin

The fossil deposits at Fossil Butte date back to the Eocene epoch, approximately 50 million years ago. This area was once a large freshwater lake, known as Fossil Lake. The rapid burial of organisms in the fine lake sediments led to exceptional fossil preservation, particularly of fish, insects, and plants.

Best Time to Visit

The best time for visiting is from late spring through early fall (May to October) when weather conditions are most favorable. Mid-morning to late afternoon offers the best natural light for viewing the geological formations. There are no tidal considerations at this inland site.

Facts & Legends

Fossil Butte is renowned for its exceptionally well-preserved Eocene fish fossils, including species like Diplomystus and Knightia, which are often found in large, layered slabs. A unique tip for visitors is to look for the subtle ripple marks preserved in some of the finer sedimentary layers, indicating ancient water currents.
