Desolation and Gray Canyons River guide will take you on a journey on Utah's Green River. The River is detailed from Ouray to Green River, Utah, which includes the usual 84-mile trip from Sand Wash to Swasey's Rapid. There is information about river permits and other administrative matters, rapids, camps, recent bear problems, my experience of a solo trip, and the regional geology that brought us these canyons. There are 33 color and several monochrome photographs. Nine detailed color topographic maps showing rapids and camps, and one area map, are included.
