The Crystal Hot Springs geothermal system is located in southern Salt Lake County, Utah 22.5 km (14 miles) south of Salt Lake City near the town of Draper. The system is immediately west of the Wasatch Mountains at the easternmost edge of the Basin and Range physiographic province within an active seismic zone referred to as the Intermountain Seismic Belt. The springs are located north of an east-west trending horst known as the Traverse Range. The range is intermediate in elevation between the Wasatch Range to the east and the valley grabens to the north and south. A series of northeast striking normal faults with a combined displacement of at least 90/sup 0/m (3000 ft) separate the horst from the Jordan Valley graben to the north. The spring system is located between two closely spaced range-front faults where the faults are intersected by a north-northeast striking fault. The fractured Paleozoic quartzite bedrock 25 m (80 ft) beneath the surface leaks thermal water into the overlying unconsolidated material and the springs issue along zones of weaknesses in the relatively impermeable confining zone that parallel the bedrock faults. Meteoric water from the Wasatch Range is warmed in the normal geothermal gradient of the province (approximately 32/sup 0/C/km) as the water circulates to a minimum depth of approximately 2.5 km (1.55 miles) via an undetermined path through aquifers and faults. Data collected at the Crystal Hot Springs system under the DOE state coupled program are presented for use by individuals interested in the system.
