2012 Map of Siskiyou Pass

About this map

Siskiyou Pass and Siskiyou Summit anchor this high-altitude traverse of the Siskiyou Mountains, where the path of Interstate 5 follows the historic gravity of the terrain. The landscape is defined by its water sources and engineering challenges, evidenced by Dollarhide Spring, McAllister Spring, and the prominent Dollarhide Curve. High points like Pilot Rock and Buck Rock overlook a network of mountain roads including Old Highway 99 S and the Old Greensprings Hwy. Settled points such as Buckhorn Springs and the small station at Steinman reflect the long history of travel through this corridor. Further east, the terrain becomes increasingly complex around Porcupine Mountain and Green Mountain, where features like Toll Road Gap suggest the earlier, more difficult routes used to navigate these summits before modern highway engineering.
