The broad Belknap shield volcano to the left seen here from Sand Mountain volcano to its NW, with the Three Sisters volcanoes in the background, is one of the youngest volcanoes in the central Oregon Cascades. The latest dated lava flow traveled 15 km W to the McKenzie River from a vent on the NE side of Belknap about 1,500 years ago.
