Soda Lake maar in west-central Nevada was erupted through sediments of the glacial Lake Lahontan. It is the larger of two lake-filled maars located NW of the town of Fallon. The basaltic maars were estimated to be less than 10,000 years old and perhaps even less than 1500 years old. Soda Lake is about 1.3 x 2 km wide and is elongated in a NE-SW direction; its rim rises only about 35 m above the lake surface. The maars are the site of a geothermal prospect that may have discharged hot springs through the end of the 19th century.
