shield volcano in theCascade Range of centralOregon , located along the Cascade Crest less than convert|7|mi|km southwest of the rim ofCrater Lake .Ice Age glaciers eroded away most of the flanks of the volcano, leaving numerous deep cirques surrounding a centralglacial horn .

Crater Lake National Park , and the summit was used as a post forfire lookout s from the 1930s to the 1950s. A convert|5.5|mi|km|1trail leads to the summit from thePacific Crest Trail offOregon Route 62 .References
