Belknap

Little Belknap (upper left) is an example of a small shield volcano in a continental margin setting. Little Belknap was constructed on the east flank of Belknap volcano and spread fresh-looking lava flows over the McKenzie Pass area of the central Oregon Cascades about 2900 years ago. Collapsed lava tubes that fed the flows diverge radially away from the summit. The summit pinnacle of Mount Washington appears at the right beyond the Little Belknap lava apron.
