Springs in Sec. 28, 29, T27N, R40E along the east side of Jersey Valley have temperatures of 29 and 57°C (Cohen and Everett, 1963; Mariner and others, 1974). The springs appear to lie along a possible projection of a mountain-front fault shown by Stewart and Carlson (1976b). A low hill of travertine and siliceous sinter over 0.8 km long is present in the spring area in SW¼ SW¼ Sec. 28, T27N, R40E (Ferguson and others, 1951b). Estimated thermal aquifer temperatures are 142 and 182°C for the silica and Na-K-Ca geothermometers respectively (Mariner and others, 1974).
Samples from five springs in Jersey Valley had temperatures ranging from 11-56ºC, with estimated reservoir temperatures of 85-143ºC and 34-178ºC using silica and Na-K-Ca geothermometers, respectively (Nosker, 1981, p. 55-57, 67, 80-81).
