The Shoshone lava field is the westernmost of the young lava fields of the Snake River Plain. It lies north of Twin Falls, Idaho and created an L-shaped lava flow 2-to-5 km in width that extends 60 km south and then west. A single radiocarbon age of 10,130 +/- 350 years obtained for lava flows from the Shoshone field straddles the Pleistocene-Holocene boundary (Kuntz et al. 1986). Black Butte Crater caps a lava shield that lies at the NE end of the flow field. The vent area contains a complex lava lake that forms a 6-part flower-petal like depression with steep-sided walls up to 30 m high that covers an area of 2 sq km. A lava tube and channel system extends 5 km SE of Black Butte Crater and displays both roofed and collapsed portions. The Big Wood and Little Wood rivers follow the northern and southern margins of the distal part of the lava flow, respectively. The voluminous flow diverted the river channels so that they now join 40 km west of their former confluence.

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.

One of a series of interlocking craters forming the complex summit of Black Butte, the vent of the Shoshone lava field, is seen here from the summit of the butte. The broad, low Shoshone shield volcano fed voluminous lava flows that traveled a small distance north towards the Mount Bennett Hills in the background, but the bulk of the flows traveled initially south and then west for a total distance of 60 km. The Shoshone lava field, erupted about 10,000 years ago, is the westernmost of the young volcanic fields of the Snake River Plain.

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.
