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.

The Global Volcanism Program is not aware of any Holocene eruptions from Soda Lakes. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Soda Lakes page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Little Soda Lake Maar
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.

Little Soda Lake, the smaller of two maars NW of the town of Fallon in west-central Nevada, is about 300 m wide. The two maars were formed by eruptions through sediments of glacial Lake Lahontan.

Basalt scoria was erupted from the Soda Lake maar in west-central Nevada. The pen points to an olivine phenocryst; the ejecta also contains abundant phenocrysts of plagioclase and less common clinopyroxene, as well as minor grains of magnetite.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
