About this map

Craters Of The Moon National Monument dominates this geological landscape, revealing a complex network of volcanic features and protected wilderness. The survey documents the Great Rift Southeast Border where the earth's crust has opened into a series of fractures and vents. Volcanic activity has shaped the terrain into distinct zones, including the jagged Aa Flow and the expansive Sentinel West Flow.

Remote landmarks such as the Bridge of the Moon and Vermillion Chasm highlight the unique erosion patterns and subterranean structures like Ice Caves and Ice Cave. Amidst the fields of Lava, the Sheep Trail provides a rare point of human navigation through the volcanic formations. Water is scarce in this high desert environment, with Hawk Reservoir serving as a significant man-made feature in the southern portion of the quadrangle.
