From The Mountain Mail (Ron Sering):

The area has been the subject of exploration dating back to the 1970s, and recent research by the Colorado School of Mines summer field camp indicated vast potential in the area. Mt. Princeton Geothermal, LLC, conducted thermal gradient testing this summer in conjunction with the CSM field camp and discovered what is to date the hottest known water source in the state.

The area’s proximity to available power lines increases the practicality of tapping the resource, using a binary method of generating electricity. The hot water is pumped to the surface and cycled through a heat exchanger to heat a special fluid with a boiling point lower than that of water. The resulting steam is used to drive turbines that generate electricity…

The lease sale will take place on November 12.
