Reconnaissance-level geologic and geophysical studies indicate that the Pilgrim Springs, Alaska, area is underlain by an intermediate temperature, liquid-dominated geothermal system of substantial magnitude. Initial exploratory drilling has confirmed the presence of the shallow, = 1-1.5 km hot water reservoir delineated by our geophysical surveys. Large artesian flow rates of 200 and 300-400 gallons/minute of 90°C water indicate that at least one good aquifer is present at shallow depths within this reservoir. Resistivity surveys suggest that the reservoir is approximately 50 m thick, may also be contained in the thick sedimentary section identified by seismic and gravity surveys, but they have not as yet been located by our initial resistivity surveys. The power presently being dissipated from the upper 50 m of the system is a minimum o f 350 megawatts.
