Where To Learn

Fossil Quarries & Digging

Plan your trip to Fossil Basin where you can unearth your very own fossil fish!

‘Dig-your-own’ fossil quarries are located in the hills surrounding ancient Fossil Lake, just west of Kemmerer and Diamondville. This 52-million-year-old limestone graveyard preserves an entire paleoecosystem, including fish, turtles, crocodiles, insects, mammals, birds and over 200 leaves. Visit Fossil Butte National Monument to learn all about this ancient world preserved in limestone. Interactive exhibits, video programs and over 300 fossils to view will help you understand the significance of this lake deposit and what it teaches us about the ancient world. Kids can become Junior Rangers and adults, Senior Rangers; visit the information desk for details. While at the monument, hike the Historic Quarry trail or the Nature Trail, take the scenic drive, and have lunch in the picnic area.
