About this map

Caribou National Forest encompasses the high terrain of eastern Idaho in this mid-1960s survey, defined by a series of prominent northwest-trending ridges. The landscape is structured around the massive Commissary Ridge and Fourth of July Ridge, which together form the backbone of the local drainage system. Numerous water sources like Willow Springs and creeks such as Fall Creek and Bear Creek cut through the topography, feeding into the wider Basin.

Logistics and travel across these heights are shown through a network of primitive routes, including the Skyline Road and various Jeep Trails. Significant landmarks for navigation and local history include Mahogany Ridge, Lightning Ridge, and Deadhorse Ridge. The presence of a Base Line and clear township boundaries highlights the systematic surveying of this wilderness area during the post-war era.
