Cascade Volcanic Arc. Union Peak is a heavily eroded shield volcano in the Cascade Range of central Oregon, located along the Cascade Crest less than 7 miles (11.3 km) southwest of the rim of Crater Lake. Ice age glaciers eroded away most of the flanks of the volcano, leaving numerous deep cirques surrounding a central glacial horn.
