A day on the Appalachian Trail is a day of ups and downs. The most relaxed hikers are those who have planned their days by looking ahead at the ups-and-downs they face before another night's rest, letting the surprises come from the views or the wildlife or the companions instead of unexpected climbs or descents. Here, for the first time for the publishers of official Appalachian Trail guidebooks and maps, is a compilation of elevation profiles of the entire Trail in 23-mile segments, produced by professional cartographers. The 9 x 6 pages are perforated, for those who want to take just whats needed for that hike. Included on theprofiles are major road crossings, springs, parking areas, and overnight shelters.
