Snow highlights rock layers in the Ely Limestone near Cowboy Pass in the Confusion Range, Millard County.
Many of the dry desert peaks of western Utah tell a story of shallow tropical seas. As much as 500 million years of deep burial, uplift, and erosion have changed layers of organic mud to cliffs and ledges of layered limestone. Closer inspection reveals abundant fossils, evidence of ancient sea life.
