On the right side of this photo are the Three Sisters Volcanoes, three composite volcanoes in the central Oregon Cascades. North Sister has a deeply eroded northern face because it has been dormant the longest. In the far left background of the photo is Broken Top, a deeply eroded extinct volcano. In the middle background is Mt. Bachelor.
