1983 Map of Siskiyou Pass

About this map

The Siskiyou Mountains define this high-altitude landscape along the border of Oregon and California. This area is dominated by the critical transport corridor over Siskiyou Pass, where the railway and power infrastructure navigate the steep climb toward Siskiyou Summit. Historical human activity is marked by sites like the Wooden Schoolhouse in the north and the Dollarhide (Site) near the western slopes. The map traces the engineering required for this passage, including the Buck Rock Tunnel and the Green Springs Powerplant near Emigrant Creek. Recreational and natural landmarks are prominent, from the Pacific Crest National Scenic Trail winding through the peaks to named water sources like Buckhorn Springs and McCallister Spring. The southern portion transitions into the Klamath National Forest, emphasizing the area's role as a protected wilderness and a vital mountain crossing.
