Pilot Rock is a prominent volcanic plug located in the western Cascade Range near the east end of the Siskiyou Mountains, just east of the Siskiyou Summit near Ashland, Oregon. Rising thousands of feet above the Shasta and Rogue valleys, it is a landmark distinguishable from over away. At 25.6 million years old, it is one of the oldest formations of the Cascade Range. The rock is protected by the Cascade-Siskiyou National Monument and the Soda Mountain Wilderness. Several trails pass near Pilot Rock, including the Pacific Crest Trail.
