This layer often erodes faster than the Entrada Sandstone above it, creating top heavy "mushroom" rocks. Balanced Rock is a great example of this. The Slick Rock Member of Entrada Sandstone represents coastal dunes. Created around 140 million years ago, this is the layer that contains most of the park’s arches.

Repeated cycles of this process created many layers of rock mixed up between the various types. Another type of shale, called marine shale, was also deposited in thin layers as wet periods onshore caused rivers to deposit larger volumes of mud and plant matter into the ocean. This extra mud was pushed further offshore rather than settling in ...
