2024 Map of Swanholm Peak

About this map

Graham USFS Airport serves as a remote aviation landmark along the North Fork Boise River, positioned near the boundary where Boise and Elmore Counties meet. This high-altitude interior of the Boise National Forest is defined by a network of historic forest routes including the North Fork Boise River Trl and the Horse Heaven Trl, which provide access to high-country summits such as Swanholm Peak and Shephard Peak. The presence of the Swanholm Lookout underscores the area's legacy of fire management and wilderness observation. A chain of alpine water bodies, notably Blue Jay Lake, Lodgepole Lake, and the Warrior Lakes, is situated south of Swanholm Ridge. To the northeast, the map transitions into the protected terrain of the Sawtooth Wilderness, where Cow Creek and Low Creek drain through steep granite corridors.
