Bog Hot Springs in Secs. 7,18, T46N, R28E have been used since the turn of the century for stock watering and irrigation of over 1.6 km2 of wild hay. Also, they are presently used for domestic water and hot mineral water baths on the Bog Hot Springs Ranch (Peterson, 1976). The springs are reported to discharge as much as 3,800L/min, and are probably associated with an active fault zone (Sinclair, 1963c). The highest surface temperature reported is 55°C (Sanders and Miles, 1974), and estimates of the reservoir temperature from chemical geothermometers are about 108°C, although the springs may be a mixed water system.
Bog Hot Springs are located at the north end of the western branch of a major lineament which extends from Soldier Meadows Hot Springs into Oregon (figure), a distance of over 105 km (Hose and Taylor, 1974). Geothermal anomalies are reported along the western branch of this lineament to the south in the vicinity of McGee Mountain (see preceding description of Baltazor Hot Springs).
