This "mountain" glitters in the sun,thanks to the small crystals that freckle its slopes. The mountain is actually an extinct selenite mine. It's still deeded to the mine owners, though it's managed by the Bureau of Land Management. It has a brief history and synopsis of selenite and its uses. It's possible to wander among the small selenite deposits sparkling along the edges of the small pit. It's a fun and spellbinding little adventure site suitable for the whole family.
