About this map

The North Fork Boise River serves as the central drainage for this section of Elmore County, carving through a landscape defined by high summits like Swanholm Peak and Graham Peak. This area, surveyed in the early 21st century, reflects a mountain economy centered on outdoor recreation and legacy infrastructure. Evidence of former industrial activity remains at the Graham Mill, situated near the Graham-US Forest Service Airport. These features indicate the region's transition from early mining or milling operations to a modern focus on seasonal access and wilderness management.

Remote backcountry sites like Graham Bridge Campground and Johnson Creek Campground offer gateway points for exploring the high-elevation basin. Further south, the terrain rises toward West Warrior Peak and the alpine Warrior Lakes, while numerous drainages such as Horsefly Creek and Lodgepole Creek feed the main river system. This map records the intersection of rugged topography and the localized developments that allow for travel through this part of the Idaho mountains.
