Fossil Hunting & Digging

Fossil Basin is a 52-million-year-old limestone graveyard that preserves an entire paleoecosystem, including fish, turtles, crocodiles, insects, mammals, birds and over 200 leaves.

Where to Go Fossil Hunting & Digging

Plan your fossil hunting trip to Fossil Basin where you can unearth your very own fossil fish! To learn more about the history of ancient Fossil Lake, stop by Fossil Butte National Monument. During the summer, the national monument has a Fossil Quarry Program where visitors can help with the fossil hunting, but you cannot keep any fossils found at the site.

However, the area has multiple private dig-your-own fossil quarries located in the hills surrounding ancient Fossil Lake, where you can hunt and dig for fossils, and often even take fossils home with you. Find more information on these private fossil quarries below.
