2013 Map of Poison Creek

About this map

The Willow Creek Lava Field dominates the northeastern reaches of this landscape, marking a distinct transition in the geology of Bingham County. To the south and west, the terrain rises into the Blackfoot Mountains and Blue Ridge, where a network of drainages including Alley Lyons Cr, Dry Miner, and Poison Cr carve through the high country. The primitive transit route of Bone Rd snakes through the topography, providing access to remote landmarks like Tanner Pass and the Commissary Basin. This 2013 survey illustrates a region defined by its water sources and public land usage, featuring the Willow Creek and Seventy Creek Access Areas and several named springs such as Butler Spring. The map documents a rugged corner of Idaho where high-desert lava flows meet mountain ridges, preserved at a time of established recreational and ranching access.
