Soda Lakes
"Two lake-filled maars, Soda Lake and Little Soda Lake, lie NW of the town of Fallon. The basaltic maars were formed subaerially, post-dating the Pleistocene glacial Lake Lahontan, and were estimated to be less than 10,000 years old and perhaps even less than 1500 years old (Garside and Schilling, 1979; Price and LaPointe, 1998). The larger maar, Soda Lake, is about 1.3 x 2 km wide and is elongated in a NE-SW direction. The 300-m-wide Little Soda Lake lies south of Soda Lake. The late-Pleistocene Upsal Hogback cones lie to the NNE of Soda Lakes. The maars are the site of a geothermal prospect that may have discharged hot springs through the end of the 19th century."  -Smithsonian Volcano Archive
