Through geologic time, Utah has been covered by oceans and inland seas as well as completely dry land. The elevation of the land surface has changed as well, ranging from sea level to over two miles above sea level.Although these images represent Utah in its present orientation, the state has not always been so.

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.

Why did Lake Bonneville drain?
The influx of water from the Bear River caused Lake Bonneville to rise until approximately 14,500 years ago when the lake breached a northern sill in Red Rocks Pass Idaho. Lake Bonneville drained catastrophically into the Upper Snake River in an event known as the Bonneville Flood [51, 53] .
