Siskiyou Pass and Siskiyou Summit define this high-elevation corridor along the Oregon California border at the turn of the 21st century. This survey documents a landscape focused on transportation and water management, where the Pacific Crest National Scenic Trail winds through the Siskiyou Mountains near the Green Springs Powerplant. Historically significant markers of earlier settlement and industry appear as the Dollarhide (Site), the railroad siding at Steinman, and a Mine Tunnel near Buck Rock. The intricate drainage patterns of Emigrant Creek and Ashland Creek are visible as they descend from prominent peaks like Pilot Rock and Little Pilot Rock. Significant portions of the southern terrain are protected within the Klamath National Forest, showing the intersection of public lands and the rugged divide between Jackson and Siskiyou counties.
