About this map

Ross Peak and Gunsight Peak command the high-elevation divide between the Boise National Forest and Sawtooth National Forest in the mid-1960s. This survey records a primitive backcountry landscape defined by its complex drainage systems and early extractive history, with the Red Horse Mine and various Prospects scattered across the mountain flanks. The terrain is intricately carved by numerous gulches and creeks, including Skeleton Creek and Mill Canyon Creek, which feed into larger forks.

Transportation is limited to a network of Pack Trails and Jeep Trails, underscoring the area's isolation before modern road development. High-altitude water bodies such as Ross Fork Lake, Bass Lakes, and Goat Lake are clustered in the northeastern quadrant near the Elmore and Camas County boundary. The map provides a detailed view of the natural hydrology, from the South Fork Ross Fork to smaller tributaries like Jumbo Creek and Fern Gulch.
