About this map

Craters of the Moon National Monument and the adjacent Craters of the Moon National Preserve dominate this volcanic landscape in Butte County. This geological survey highlights the distinctive volcanic features that characterize the region, most notably the Great Rift and volcanic cinder cones like The Watchman and The Sentinel. The terrain is defined by massive basaltic formations such as the Serrate Flow, Black Flow, and Little Prairie Aa Flow, illustrating the recent volcanic activity of the Snake River Plain.

Water is scarce across this arid expanse, marked primarily by isolated features like Surprise Waterhole, Bearsden Waterhole, and Little Prairie Waterhole. Unusual geological occurrences are noted at Huddles Hole and Bridge of Tears, while human movement or historical exploration is hinted at by the Tom Thumb Tunnel. The map also identifies prominent landmarks used for navigation across the lava fields, including Round Knoll and Little Prairie.
