2017 Map of Poison Creek

About this map

The Blackfoot Mountains dominate this high-desert landscape in southeastern Idaho, where the volcanic heritage of the region is clearly visible at the Willow Creek Lava Field in the northeast. The terrain is a network of ridges and drainage basins, notably the Commissary Basin and the prominent Blue Ridge. This area is defined by its complex hydrology, with numerous named streams such as Poison Creek, Levi Hawkley Cr, and Alley Lyons Cr carving through the slopes. Historically, transportation through this rugged portion of Bingham County has been dictated by the natural gaps in the mountains, such as Tanner Pass, and the primary thoroughfare of Bone Rd. The presence of water sources like Butler Spring and named seasonal drainages like Dry Miner indicates the critical importance of water management for the ranching or land use patterns in this high-elevation environment.
