Snow highlights cross-bedding on the sides of buttes and mesas along the Clear Creek drainage on the east side of Zion National Park. Cross-beds in the nearly 2,000-foot-thick Jurassic-age Navajo Sandstone formed in ancient sand dunes and reflect changing wind directions as the sand was being deposited.

Boulders of Cretaceous-age Dakota Sandstone act as protective caps and inhibit erosion of the soft Jurassic-age Entrada Sandstone beneath, allowing hoodoo spires to form. Water cascading over the Entrada Sandstone during rainstorms has carved an intricate network of rills.

Spire-like formations called “toadstools” form where resistant sandstone boulders of Cretaceous-age Dakota Formation (toadstool caps) protect the underlying, softer, Jurassic-age Entrada Sandstone (toadstool stems) from erosion. Beneath their protective caps, the spires stand tall above the surrounding eroded landscape.
