Rocks are always happy to see you. But some rare times they show it on the outside.

This beautiful rock formation is part of Entrada Sandstone, a layer of prehistoric desert dating back to the Jurassic period!
Sandstone dates to the Early Jurassic when the American West was covered in an ancient, flat desert. The elegant striations in the sediment are the result of the original deposition of the sand dunes, which were later exposed by erosion.
