While today it’s a desert – dry as a bone – for hundreds of millions of years, starting around 570 million B.C., western Utah was under the ocean. California and Nevada weren’t around, and the west coast of North America ran right through our now-desert state.

Why are Utah mountains red?
The red, brown, and yellow colors so prevalent in southern UT result from the presence of oxidized iron–that is iron that has undergone a chemical reaction upon exposure to air or oxygenated water. The iron oxides released from this process form a coating on the surface of the rock or rock grains containing the iron.
