Siskiyou Summit (also Siskiyou Mtn. Summit; also referred to as Siskiyou Pass) is a summit (high point) on Interstate 5 (I-5) in the U.S. state of Oregon. It is distinct from Siskiyou Pass, which is a nearby, historical mountain pass.[1][2] Siskiyou Summit is situated in the Siskiyou Mountains, approximately 4 miles (6.4 km) north of the California border.[3] At 4,310 feet (1,310 m), it is the highest point on Interstate 5.[4] When the highway was rebuilt on its current alignment, road cutting lowered the elevation of the summit by 49 feet (15 m).[5]
