ABSTRACT Utah (USA) is naturally gifted with bountiful geothermal energy resources. Located along the eastern boundary of the Great Basin, a physiographic region with abundant geothermal heat close to Earth’s surface, Utah’s geothermal resources are a product of several large-scale geologic processes working together: regional hydrological systems flush water from high mountain ranges through adjacent lowlands, accommodated by heavily fractured bedrock and (still active) crustal-scale faults that bound each valley, and sweep geothermal energy from a nearly limitless supply of deep subsurface heat radiating from a relatively shallow intracontinental mantle and geologically recent volcanic intrusive suites. Intended for students and working professionals alike, this field trip showcases a wide range of geothermal resources that are in different phases of exploration and/or development, from established geothermal power plants operating within traditional hydrothermal systems since the 1980s, to world-class, natural field laboratories where experimental technologies are being developed to engineer efficient closed-system fracture sets within hot rock bodies, to emergent geothermal resource leads at the very beginning of subsurface characterization to assess their true resource potential. Field-trip attendees will explore the Black Rock Desert, visit two different working geothermal power plants, tour the U.S. Department of Energy–funded Frontier Observatory for Research in Geothermal Energy (FORGE) site for Enhanced Geothermal Systems research, investigate a siliceous sinter deposit at the Opal Mound fault zone, experience scenic drives through Utah’s Renewable Energy Corridor, and learn ways in which geoscientists conduct geothermal energy resource assessments in areas with strong blind/hidden geothermal resource potential.
