About this map

The Middle Fork Boise River carves a deep, winding path through the heart of the Boise National Forest in this 1970s topographical record. This high-altitude wilderness area is characterized by steep drainage systems and prominent peaks like Grand Mtn and Granite Mtn. The landscape is a network of water and primitive access routes, where name-labels like Wren Creek and Bear Creek reveal the natural inhabitants of the drainage basins.

Evidence of geothermal activity is present at sites such as Spr (Hot) and Spring (Hot) along the river corridor. Human movement across this terrain was largely restricted to a system of trails, including the Lost Man Trail and various stretches labeled Pack Trail or Jeep Trail, indicating a remote backcountry environment primarily used for forest management and recreation. The convergence of the Roaring River with the main fork highlights the powerful hydrology that shapes this part of Elmore County.
