About this map

The Pioneer Mountains dominate this high-altitude landscape on the border of the Challis National Forest and Sawtooth National Forest. This region is defined by deep drainages and sharp ridges, where the E Fork Wood River and Little Wood River originate from alpine basins and cirque lakes. Notable water bodies such as Arrowhead Lake, Windy Lake, and the tiered Upper Box Canyon Lake and Lower Box Canyon Lake are tucked into the steep topography of the Custer and Blaine County line.

Industrial history is preserved in the location of the Iron Mine, situated along Iron Mine Cr near P. K. Pass. The map traces a network of remote canyons and gulches, including Paymaster Gulch, Baron Gulch, and Snowslide Gulch, which suggest the challenges of early prospecting and transit. Prominent summits like Grays Peak and Old Hyndman Peak serve as anchors for this wilderness area, which remains largely inaccessible except by the E Fork Rd.
