Corwin Springs is just north of Yellowstone Park and is within the boundaries of the geothermal protection barrier. There is little opportunity to develop the geothermal resources of the immediate area due to the perceived potential impact to the geysers and hot springs of Yellowstone National Park. The main spring is located about 1.5 miles south of Corwin Springs, along the Yellowstone River. Water was piped from here to Corwin for the resort's use.
The surface temperature of the water is 149° F at the main spring. Geothermometry indicates reservoir temperatures of 160-324° F. Structural investigations indicate a major structural intersection in the area (Struthsacker, 1976). No exploration drilling has been completed in the immediate area.
