Blue Lake Rhino Cave
About 14 or 15 million years ago, a rhino was overtaken by basalt magma flows. The cooling magma formed rock around the rhino’s body, which eventually decayed. Like a plaster cast, the rock remained in the shape of the rhino. And guess where you’ll find this amazing fossil? In Eastern Washington, a few hundred feet above what is now called Blue Lake.
The cave mouth can be viewed from the lake’s surface (you can rent a rowboat at Sun Village Resort). Skilled rock climbers can even crawl through the cave. Rumor has it that you can still see the impression of the rhino’s belly button.
