Little Belknap (upper left) is an example of a small shield volcano in a continental margin setting. Little Belknap was constructed on the E flank of Belknap volcano and erupted lava flows over the McKenzie Pass area of the central Oregon Cascades about 2,900 years ago. Collapsed lava tubes that fed the flows diverge radially away from the summit. The summit of Mount Washington appears above the horizon to the right.
