Most of the known geothermal resources in Utah occur along the transition from the Colorado Plateau to the Basin and Range Province. Resources in current use include direct-use and power generating geothermal resources. The green regions show well-characterized areas where new resources can be developed. The pink region outlines a part of the Great Basin that has potential prospects defined by surface fault architecture. The black dots are wells that have elevated heat flow measurements, indicating a potential for geothermal resource. The Black Rock Desert has the most attractive potential for future development.
