Geologic and topographic map of Utah. Geologic data from Horton et al. (2017) using the maximum age values for each mapped unit. Topographic data are derived from the Shuttle Radar Topography Mission (SRTM GL3) Global 90m (SRTM_GL3) (Farr, T. G., and M. Kobrick, 2000, Shuttle Radar Topography Mission produces a wealth of data. Eos Trans. AGU, 81:583-583).
Utah State Rock: Coal
Coal is found in 17 of Utah’s 29 counties, but coal mining is primarily concentrated in Emery and Carbon counties, where coals formed in the Uinta Basin. Most coal mined in Utah is bituminous.
Utah State Mineral: Copper
The Kennecott’s Bingham Canyon mine in the Oquirrh Mountains is the world’s largest open-pit copper mine. Copper is a versatile metal widely valued for its capacity to conduct heat and electricity, and is used in electronics, transportation, plumbing, and alloys, among many other areas.
Utah State Gem: Topaz
Topaz is a hard, semiprecious gem that is found in Beaver, Juab, and Tooele counties in Utah. At Topaz Mountain, which is in the Thomas Mountain Range in Juab County, topaz and other minerals such as beryl and opal are found in relatively high abundance in the cavities of Neogene-aged rhyolites.

Utah's Highest and Lowest Elevations
Topographic map of Utah with physiographic regions and point of highest elevation identified. Topographic data are derived from the Shuttle Radar Topography Mission (SRTM GL3) Global 90m (SRTM_GL3) (Farr, T. G., and M. Kobrick, 2000, Shuttle Radar Topography Mission produces a wealth of data. Eos Trans. AGU, 81:583-583).
Highest Elevation: Kings Peak
At 4125 meters (13,534 feet), Kings Peak is Utah's highest point, located in the Uinta Mountains of north-central Duchesne County. The peak is regarded as the hardest state high point to climb without special rock climbing skills or a guide; the easiest trail to the summit requires a 47-kilometer (29-mile) round-trip hike.

Lowest Elevation: Beaver Dam Wash
Beaver Dam Wash, at the Utah-Arizona state line in Washington County, is the lowest point in the state at 664 meters (2178 feet) above sea level.
