2010 Map of Pratt Butte

About this map

Pratt Butte and Rattlesnake Butte anchor this high-altitude landscape in Blaine County, Idaho, where the volcanic geology of the region is clearly mapped by the U.S. Geological Survey. The terrain is characterized by expansive, open flats punctuated by these isolated volcanic rises, a typical formation within the Snake River Plain volcanic province. Human presence is marked primarily by ranching and water management infrastructure, most notably at Heifer Reservoir in the northeastern corner. Transportation through this arid environment is limited to unpaved routes like Pratt Lake Rd, which winds through the basin to connect the scattered water resources and landmarks. This 2010 survey reflects a modern period of topographic mapping, detailing the subtle drainage patterns and landforms of a sparsely populated but geographically distinct high desert region.
