Siskiyou Mountains terrain dominates this borderland survey, where the peaks of the Siskiyou National Forest meet those of the Six Rivers National Forest and Klamath National Forest. The landscape is defined by its massive drainage systems, particularly the Middle Fork Smith River and its numerous tributaries like Knopti Cr and Stephens Cr. Modern engineering is visible at Hazel View Summit, where the Randolph Collier Tunnel carries travelers through the ridge near the Oregon-California border.
