Abstract

Water samples from 31 wells and springs in eastern Idaho and western Wyoming were collected to help evaluate the potential geothermal resources in the Teton River area. Water analyses included anions and cations, oxygen-18, deuterium, and several minor elements. Actual temperature of the thermal waters ranged from 23 to 49C. Estimated aquifer temperatures, as derived from geochemical thermometers, ranged from 45 to 145C based on sodium-potassium-calcium ratios. Using the cation thermometer, two analyses indicated aquifer temperatures lower than actual measured temperatures. Using a mixing model method, estimated temperatures ranged from 205 to 320C, the higher being of questionable value. The different methods used showed little correlation. Based on isotope data, the warm waters may be of local meteoric origin and not heated enough to react significantly with aquifer rocks; or, they originated as precipitation at high altitude and great distance from the area.
