2024 Map of Reservoir Mountain

About this map

Blackfoot Reservoir dominates this high-altitude landscape in Caribou County, where the sprawling water body is punctuated by several prominent landforms including Split Island, Cormorant Island, and Bay Island. The terrain is characterized by the volcanic history of the region, specifically the Blackfoot Lava Field which sits adjacent to the reservoir's western reaches. Rising above the water and lava flows is Reservoir Mtn, a significant topographic feature that overlooks the complex network of mountain drainages like Bear Creek and Chicken Creek. A modest network of backcountry access routes, such as Government Dam Rd and the aptly named Skinny Dip Rd, provides the primary means of navigating this remote portion of the Blackfoot Mountains. These roads trace the rugged contours and connect the shoreline features like Chicken Point to the surrounding peaks.
