Exhibits

Crater Rock Museum houses the finest displays of gems, minerals rocks, and fossils on the West Coast: world-class minerals, petrified woods, fossils, Native American artifacts, and much more!

Fluorescent Mineral Display

Our Fluorescent Mineral Display room is a favorite among visitors. Close the curtain, set the time, and watch the fluorescent show in the darkened room. The rocks glow different colors under different light. This is a must-see when visiting the museum.

Fossil Fish From the Green River Formation

When you visit the Fossil Room, look for the fossil fish specimens from the Green River Formation. The Green River Formation is from the Eocene era (50 million years ago!) and records the sedimentation in a group of lakes in three basins along the Green River in Colorado, Wyoming and Utah. Our Green River Formation is from Wyoming. Our particular fossil slab is extremely rare, and features an abundance of perfectly preserved fossil fish on both sides.

Minerals

Our mineral specimen collection is among the best on display along the entire West Coast. You can view gold, gems, and commercial-use minerals and see how some of them are used every day. Click photos to enlarge!

Agates, Geodes & Thunder-eggs

We have a huge selection of cut and polished geodes and “thunder eggs” nestled among specimens of petrified wood, ancient petrified pine cones, and palm trees.

Fossils

We’ve dedicated an entire room in the museum to fossils and we think they are some of the best available. Click photos to enlarge!

Scrimshaw

This collection is one of the rarest and most complete you’ll ever see. The artwork on these pieces of ivory are just amazing. Make sure you spend time looking at the detail in each piece. Donated by the estate of David Holmes of “Harry and David’s” fame. Click photos to enlarge!
