Dyke Hot Spring is about 18 km south of Howard Hot Spring in Sec. 25, T43N, R30E. It lies at the southern end of a fault which forms the east boundary of the Pine Forest Range. The temperature is reported to be as high as 70°C (Sinclair, 1962a). The estimated thermal aquifer temperatures are128 and 137°C, although these are from mixed waters, and may be significantly below the true thermal-aquifer temperature. A trace of travertine was reported (Mariner and others, 1974).
