About this map

Bonnerille Hot Springs and the surrounding wilderness of the Boise National Forest dominate this 1970s topographic study. The landscape is defined by the steep drainage basins of the South Fork Payette River, where remote infrastructure such as the Warm Springs Forest Service Station and the Warm Springs Landing Strip supported backcountry management and recreation.

Evidence of the era's forest access is found in the network of Pack Trails and local roads serving the Warm Springs Campground and Warm Springs Picnic Area. Notable watercourses like Eightmile Creek, Castro Creek, and Warm Spring Creek carve through the high terrain, which culminates at the peak of Eightmile Mtn. This map captures a specific moment in Idaho's forest history when aviation and improved campgrounds began to open the interior canyons to more frequent use.
