About this map

The Blackfoot Mountains dominate this high-altitude landscape of Bingham County, where complex drainage systems define the rugged Idaho terrain. The map captures a transition point for several key waterways, including the winding course of Willow Creek and the headwaters of Poison Creek. While the area is largely characterized by uninhabited topography, evidence of human activity and early surveying is marked by features such as the Borrow Pit and a lone Grave located near Mill Creek.

Deep basins and named passes suggest a history of seasonal travel and ranching, with Commissary Basin and Tanner Pass serving as natural corridors through the peaks. Water sources are vital here, as shown by the network of seasonal streams like Seventy Creek and Levi Hawkley Creek that cut through the eastern slopes. This 1981 edition provides a detailed look at the land shortly after field checking in 1975, reflecting the area's enduring character as high-country range and watershed.
