Hot springs along the Truckee River about 10km west of downtown Reno (SW¼ NE¼ Sec. 13, Tl9N, R18E) were named for Sam L. Laughton, who was the proprietor of a spa on the site in the mid-1880s. They were originally called Granite Hot Springs, but the name Lawton was used for a station on a spur of the Southern Pacific Railroad (Carlson, 1974). The springs had a temperature of 48.9°C, and an artesian well is reportedly 60°C (R. B. Scheibach, written comm., 1975). Lawton Hot Springs lie at the northwestern end of a 12-mile-long zone of thermal groundwater that extends from Steamboat Hot Springs to the southeast. The River Inn hotel-casino, built in the 1980’s on the site, planned to use the hot springs water in a bathhouse, but the hotel-casino never opened for business. The site was visited in April 2006 and the River Inn complex had been fenced in and was locked, but access was gained from Manhard Constuction. The site had two wells drilled in 1981, but the pumps have no power and samples could not be collected directly. Thermocouple temperatures in the wells were 44-46°C at ~10’ below ground level. Water seeping under the footings of the building is 46°C at the surface, however its specific source is unknown. The discharge pipe for the footings bilge pumps was sampled in May 2006 and had a temperature of 46ºC. A warm water well (29.4°C) is known in the vicinity of Mogul, about 1.5 km to the west (SE¼ SW¼ SW¼ NE¼ Sec. 14, T19N, R18E) (L. Garside, unpub. data, 1986).
