White Rim Road surrounds the Island in the Sky at Canyonlands National Park. Here at Upheaval Bottom (the low end of Upheaval Canyon) the road parallels the Green River. You cannot see the river from here. It's about a quarter mile west of the road. The surrounding mesas Horsethief Point, Buck Mesa, Bighorn Mesa and High Spur rise about 1000 feet above the valley floor here at 4000 feet.
