We stopped for lunch on a sand bar on river left, just downstream of Chuar Rapid at the mouth of Lava Canyon (not to be confused with Lava Falls later on). We passed beneath the Paleozoic about half an hour ago and are now in the ancient, tilted sedimentary and volcanic rocks of the Grand Canyon Supergroup.

In a place this big, sometimes the most interesting stuff is the small stuff. Here's an oversteepened shoreline bluff and a small barrier beach within 20 meters of each other.
