Utah lies in the middle of the Rocky Mountains. The eastern part of Utah belongs to the Colorado Plateau. The western part of Utah is also very flat, with salt flats and the Great Salt Lake, an inland sea formed at the end of the last ice age by the melting glaciers. Today this area is extremely dry, because it is surrounded by mountain ridges.
Utah has limesone in many places, always in small deposits. But it has no big cave, just many arches, natural bridges and abris.
The geologic complex situation in the middle of an orogeny is ideal for various kinds of ore and the resulting mining activities. The most important mining area is located 50 kilometers southeast of Salt Lake City around Park City in the Wasatch Mountains. A belt of silver and lead ores was mined in numerous mines.
