Popular with hikers and climbers, Pilot Rock stands out as one of the most striking features of the Cascade-Siskiyou National Monument. The remnant of an ancient volcano, Pilot Rock is visible from much of the Shasta Valley in northern California and parts the Rogue Valley in southern Oregon. Over time, the exterior volcano eroded away, leaving behind the impressive columnar basalt of the ancient volcano’s central vent. Fossil sites in the vicinity of Pilot Rock contain leaf impressions and conifer cones that became embedded in volcanic ash beds 25-35 million years ago.
In 2001, a pair of peregrine falcons reoccupied a historic nest site. In order to protect the falcons which are protected as a species of special concern, there are some limitations on these activities.
