McKenzie Pass is a summer-only road which crosses open lava
flows between the Three Sisters and Mt Washington. We truck-camped in the
pass and went for a day-hike to Little Belknap Crater and then Belknap Crater.
Along the way we had some great views, saw some lava flow features, and
explored a shallow cave. The last photo is a panorama of Belknap Crater
with Kerry on the far left.
