2020 Map of Pratt Butte

About this map

Craters Of The Moon National Preserve dominates this portion of the Idaho landscape, showcasing the geological intensity of the Eastern Snake River Plain. The terrain is defined by the Great Rift, a massive volcanic fissure system that bisects the region and influences the placement of local landmarks. Standing as prominent volcanic features are Pratt Butte and Rattlesnake Butte, which rise above the surrounding lava fields and high-desert scrub. The boundary between Blaine and Butte counties runs vertically through the western portion of the sheet, cutting through sections of the preserve. While the area is largely characterized by its volcanic history, small-scale water management is evident at Heifer Reservoir in the northeast, providing a rare point of managed surface water in an otherwise arid and geologically complex environment.
