Howlock Mountain is a heavily eroded shield volcano in the Cascade Range of central Oregon, located along the Cascade Crest just north of Mount Thielsen. Ice Age glaciers eroded away most of the flanks of the volcano, leaving numerous deep cirques[3] surrounding a central ridge capped by several horns. The summit of Howlock Mountain lies along the border between Douglas County and Klamath County.
