Water temperatures at Howard Hot Spring (Secs. 4,5, T44N, R3 IE) are usually reported to be 48-58°C, although Sinclair (1962a) listed one spring with a temperature of 73°C. Mariner and others (1983) reported the temperature as 56ºC. Several hot springs were described by Waring (1965) and Stearns and others (1937) for which detailed location data are lacking, but which may refer to Howard Hot Spring. Hose and Taylor (1974) reported that siliceous sinter is present, and they prefer a 128°C estimated reservoir temperature using the silica (Conductive) geothermometer. Mariner and others (1983, p. 105) estimated a reservoir temperature of 71ºC and 80ºC using the silica and Na-K-Ca geothermometers, respectively.
