The Escalante riverbed is sandy, wide, and shallow and the valley is enclosed by Navajo sandstone. I've edited my GPS track to more closely follow the actual trail but, in practice, you'll probably zigzag across the riverbed as things catch your eye. Don't be surprised if you develop a preference for the south side where the most interesting features are.
Look for the Escalante Natural Bridge
along the way, as well as an Anasazi cliff dwelling slightly west of the bridge, which include petroglyphs, and a crescent shaped Escalante Natural Arch another 0.4 miles further west. This run is ideal in the fall, e.g. early October, when yellow leaves are framed by enormous varnished sandstone walls.
