Diamond Peak is a shield volcano in south west Oregon and is part of the Cascade Range. The 8,744 foot (2,665 meter) mountain is in the Diamond Peak Wilderness and near Willamette Pass.
Composed of basaltic andesite, the volcano is older than the last ice age but probably younger than 100,000 years. It first began erupting from its northern summit and then from a new vent a little to the south, which is now the main peak. The mountain has several cirques from glacial erosion. It lies directly on the Cascade Crest and therefore receives a heavy snow pack. Snow fields on the northern side may have been glaciers as recently as 100 years ago.[2]
