Dissolution of subsurface salt caused the collapse of the Salt Valley anticline, forming vertical fractures in the Jurassic-age Entrada Sandstone. Weathering along the fractures has produced the spectacular fins, towers, and arches in the Devils Garden section of Arches National Park.

Eroded fragments of a dark ironstone layer contrast sharply against the pale-orange Jurassic-age Navajo Sandstone at Snow Canyon State Park. In places, the iron- and manganese-rich ironstone forms a resistant cap at the top of sandstone columns or pillars called hoodoos.

Quartzite of the 900 million-year-old Big Cottonwood Formation holds up the rugged headwall of Mary Ellen Gulch. Well-preserved ripple marks and mud cracks indicate the Big Cottonwood Formation was deposited in the tidal zone of a shallow sea.
