1996 Map of Broken Rib Mountain

USGS Topo · Published 1999

About this map

Broken Rib Mountain dominates this rugged wilderness corridor in the late 1990s, where the Siskiyou National Forest and Six Rivers National Forest meet at the California-Oregon state line. The landscape is defined by the steep drainages of the Middle Fork Smith River and the Illinois River, which provide the hydrological framework for this protected mountain terrain. Human activity is concentrated near the Randolph Collier Tunnel and the Collier Roadside Rest along the western edge, while the interior remains a vast roadless area accessible primarily by trails. Significant landmarks for local history and topography include Sanger Peak, Youngs Valley, and the archaeological footprint of Camp Chicago (Site). The map details several scattered prospects and mines, indicating a legacy of resource exploration that predates the modern designations of the Siskiyou Wilderness and the Smith River National Recreation Area.
