2011 Map of Lower Monumental Dam

About this map

The Snake River carves a deep path through this portion of Franklin County, where the massive infrastructure of the Lower Monumental Dam stands as the central landmark. This 2011 survey reveals a landscape of industrial river management and aviation, featuring both the Lower Monumental State Airport on the southern bank and the Hille-Kimp Airstrip to the north. Small settlements and rail-related points like Windust, Farrington, and Scott line the river's edge, marking the historical transit corridor through the canyon. The surrounding terrain is defined by dramatic geological features, including Devils Canyon, Box Canyon, and Bouvey Canyon, which cut through the high plateau. Road networks like Lower Monumental Rd and Hunt Rd provide access to this specialized engineering site, while the scattered place names like Matthew and Monument recall the area's agricultural and local history before the river was fully harnessed for power.
