Waterproof, Tear-Resistant, Topographic Maps. The Appalachian Trail (AT) Map Pack Bundle of Pennsylvania includes two Topographic Map Guides that cover the entire AT in the Keystone State. The map follows the ridges of the Appalachian Mountains and weaves in and out of suburbia. This section of trail, which is notoriously rocky, is rich in history with traces of early industry-charcoal furnaces, railroads, and coal mining. Each AT Topographic Map Guide includes detailed topographic maps at a detail of 1 inch = 1 mile. Each page is centered on the A.T. and overlaps with the adjacent pages so there is little chance of getting lost. Along the bottom of each page is a trail profile that shows the distance between shelters, camping areas, and trail access points. The map and trail profile provide a step by step visual guide to hiking the trail, mile by rugged mile. The Topographic Map Guide is built for all levels of hiking enthusiasts, from the day tripper to the multi month 'thru-hiker'. The front pages of the printed Topographic Map Guide include resupply information, town inset maps, camping options, and much more. Buy the Map Pack and save over 15%! The Appalachian Trail: Pennsylvania [Map Pack Bundle] includes: - Map 1506: Raven Rock to Swatara Gap [Pennsylvania]. - Map 1507: Swatara Gap to Delaware Water Gap [Pennsylvania]. More convenient and easier to use than folded maps, but just as compact and lightweight, National Geographic's Topographic Map Guide booklets are printed on 'Backcountry Tough' waterproof, tear-resistant paper with stainless steel staples. A full UTM grid is printed on the map to aid with GPS navigation.
