The McKenzie highway 242 crosses the barren lava fields on the SE flank and offers with spectacular views toward Mt. Jefferson and the Three Sisters volcanoes. Introduction:Belknap is a basaltic to basaltic-andesite shield volcano, topped by the Belknap Crater, a cinder cone, and the shield volcano of Little Belknap to the west. Lava flows from these vents have spread to all directions and created an impressive landscape of lava flows. The youngest of these flows traveled 15 km west into the McKenzie River valley. |
