Capitol Reef National Park in Utah got its name from the white domes of Navajo Sandstone that resemble capitol building domes and the rocky cliffs – which act as a reef, creating a barrier to travel. The park is one of the best geological classrooms in the world. Rock layers in Capitol Reef reveal ancient environments as varied as rivers and swamps, Sahara-like deserts and shallow oceans, each marking an era through almost 200 million years of Earth’s history.
