2023 Map of Siskiyou Pass
USGS Topo · Published 2023About this map
Siskiyou Pass serves as the focal point for this survey of the rugged boundary between Oregon and California. The landscape is defined by its deep history as a transportation corridor, where the modern Old Hwy 99 S and the Pacific Crest National Scenic Trl parallel the historic route of the Or Cal Wagon Trail. This convergence of trails and roads at Toll Road Gap highlights the enduring strategic importance of this gap in the Siskiyou Mountains.
