A guide for raft and kayak people to the multiday trip down Desolation and Gray Canyons, on the Green River in Utah. For this third (2003) edition, all the maps were redone and improved. Rapids and camps are marked. Launch and take-out areas are detailed. Regional geology is described, as is a solo trip down the river. Ten pages of color topographic maps, 35 color photographs, eight B&W photos. From the introduction: "A guidebook should try to express how it feels to run the river."
