Cappy Mountain

Cappy Mountain is a stratovolcano in Oregon’s Cascade Range in Klamath County, along the northern border of the Mount Thielsen Wilderness. It stands within a cluster of volcanic peaks, with Mount Thielsen to the south and Cowhorn Mountain and Sawtooth Mountain to the north and northwest. Its last eruption occurred in the Pleistocene, placing its activity in the geologically recent past rather than the present. Together with nearby features such as the Cinnamon Butte volcanic field and Howlock Mountain, it forms part of the broader volcanic landscape of this section of the Cascades.
