UGS scientists are part of an exciting research team led by the Energy and Geoscience Institute at the University of Utah that will study new techniques for harnessing the Earth’s heat to generate electrical power. Our team will evaluate the establishment of an enhanced underground geothermal project about 10 miles north of Milford, Beaver County. The research is one of five proposals currently funded by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy. Check it out —

Someone dropped a box of yellow crayons in this hot water. Now, the algae and sulfur crystals can’t stop coloring! Just kidding, there’s no crayons in this natural color field.

Yellow sulfur crystals and various colors of bacteria and algae give these hissing steam vents and bubbling pools an otherworldly look. This landscape is a recent and evolving phenomenon resulting from changing groundwater levels associated with nearby geothermal power generation.

This 27-page report analyzes new detailed (1:12,000 scale) geologic mapping of a 14 square mile area centered by the high-temperature (350°F) Sulphurdale heat source, which at the surface makes up a circular area about a mile in diameter that is likely caused by a magma body at depth. A former small steam-driven geothermal electric power plant in the circular area is being replaced by a larger plant (Enel Green Power North America) that will use binary technology. Five cross sections tied to and at the same scale as the map help interpret the likely extent of the geothermal resource. Sulfur derived from evaporites at depth was initially mined at a solfatara above the heat source; associated sulfuric acid seeped downward to remove the Kaibab Limestone and Toroweap Formation from the subsurface.

Crews in western Utah have been working away at a seemingly endless task in picturesque — but very dangerous — places.



You don’t have to drive to the Sierras for exceptional gem-hounding or big-wall rock-climbing. Southern Utah’s pristine Mineral Mountains just west of Beaver will fulfill any stone enthusiast’s yearning for rock.

Spectacular granite crags loom high above Ranch Canyon in the Mineral Mountains. An immense aggregation of smaller intrusions, the 18 million year- old  (Miocene-aged) Mineral Mountains batholith (large body of intrusive igneous rock) is the largest exposed batholith in Utah.
