Waterproof, tear-resistant topographic map guide. The Springer Mountain to Davenport Gap Topographic Map Guide makes a perfect traveling companion when traversing the Georgia, south-eastern Tennessee and south-western North Carolina, section of the Appalachian Trail. Each A.T. Topographic Map Guide includes detailed topographic maps at a detail of 1 inch equals 1 mile. Each page is centred 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 showing distance between shelters, camping areas and access points.
