1973 Map of Chilcoot Peak

USGS Topo · Published 1975

About this map

Riordan Pack Trail and other primitive routes weave through this high-elevation terrain within the Boise National Forest in the early 1970s. The landscape is defined by its drainage systems, with the North Fork and South Fork feeding into Bear Creek and Trapper Creek. Strategic points like the Riordan Lookout and summits such as Chilcoot Peak and Trapper Mtn provide orientation for those navigating the backcountry. High mountain basins hold small water bodies including Riordan Lake, Black Lake, and Chilcoot Lake. Transportation in this era relied heavily on non-motorized infrastructure, indicated by the Thunder Mountain Road (Pack) and the Summit Trail (Pack). Evidence of resource exploration appears at a Prospect located near Buck Creek, while natural landmarks like Pistol Rock and the wide openings of Trapper Flat offer distinct waypoints for surveyors and travelers alike.
