About this map

Siskiyou National Forest and Six Rivers National Forest converge at the Oregon-California border, forming a landscape of steep ridgelines and remote alpine waters. This 2018 survey captures the rugged terrain of the Klamath-Siskiyou region, where the Randolph Collier Tunnel carries travelers beneath Hazel View Summit along the modern highway route. The map highlights significant peaks including Broken Rib Mtn, Chicago Peak, and Sanger Peak, which overlook deep drainages like Sanger Canyon.

Historic water management is evident in the presence of the Osgood Ditch near the E Fork Illinois River, a legacy of the region's mining and development history. High-elevation lakes such as Whisky Lake and Sanger Lake sit tucked beneath the summits, while the Wounded Knee Trl provides access to southern landmarks like Wounded Knee Mtn. This area serves as a vital hydrological headwater, feeding both the Smith and Illinois River systems through numerous named creeks like Broken Kettle Cr and Bybee Gulch.
