The Belknap Crater scoria cone provides a panorama of recent volcanism in the McKenzie Pass area. Younger lava flows from scoria cones on the north flanks of North and Middle Sister volcanoes in the background merge with flows from the Belknap shield volcano. Most of these flows were erupted in the past few thousand years. In the left foreground, lava flows from Belknap diverge around kipukas, islands of older rocks.
