Adams (1944) reported a water analysis for a hot spring at Eagle Salt Works. No other location data were reported, but Garside and Schilling (1979) assumed the spring to be in the area of salt springs on northeast side of Eagle Marsh, near Eagle Rock, in Section 35, T22N, R26E. The water analysis is similar to those reported for the Bradys Hot Springs area 6 km to the northeast, and considerably lower in NaCl than later analyses of the salt springs (e.g., Harrill, 1976, table 9) near the abandoned salt works. Adams (1944) only reported on hot springs from 21 well-known Nevada geothermal areas, and Bradys, although well known at the time, was not one of them. We tentatively conclude that the Adams (1944) analysis was made on water from Bradys Hot Springs. It may be that Adams took the spring name from the nearby salt works, although it went out of business in about 1916 (Myrick, 1962). Temperature-gradient drill-hole data (Benoit and others, 1982; Olmsted and others, 1986) do not indicate hot groundwater in the area of the salt springs and shallow wells that were used for production of salt in the late 19th and early 20th centuries (Papke, 1976. Three salt wells in NW¼ NE¼ NE¼ Section 35, T22N, R23E have temperatures of 16.3–18.6°C (Mark Coolbaugh, written commun., 2003). Benoit and others (1982, table 5) reported a 15.6 ºC temperature for one of these, and high NaCl. An unpublished analysis of a sample collected in 1983 by R.H. Mariner and W.C. Evans (R.H., Mariner, unpubl. data) yielded estimated reservoir temperatures of 148ºC (Na-K-Ca geothermometer) and 137ºC (quartz geothermometer). Benoit and others (1982) suggested that the saline groundwater of this area represented discharge from a thermal aquifer extending southwest from in the Desert Peak geothermal area, located to the northeast. Wood-cribbed salt wells, located in NW¼ NE¼ NE¼ Sec. 35, were full to the surface or slightly flowing in 2005; the present flow to these wells may be influenced by injection of spent geothermal fluid from the Bradys power plant. Shallow (ca. 275 m) injection wells, located about 1.8 km to the northeast, began injecting a portion of the Bradys spent fluid in early 2000 (Krieger and Sponsler, 2002).
