Aimed at Grand Canyon river runners who want to get the most hiking out of their river trip, these hikes may take an hour or be from sunrise to sunset. Useful for planning your itinerary and for stuffing in your fanny pack. Backpackers who can read backwards (from the bottom actually) will appreciate it too. Forget the next rapid, look up! Tom has added 25 more hikes to the original 75. The maps are improved and the text updated. Soft cover, 240 pages
