These are not 40 year old, scanned topo maps. Made from the latest data available, presented in uniform styles and colors, consistent unit of measure throughout and 10 types of land cover not seen in any other complete map sets.
Each section is preceded by a "Meta-Data" page and "Section Overview Map". The meta-data page has a section elevation chart and climate data for every month of the year. You'll also find all resupply departure points, road crossings, lakes within 1/4 mile of the trail, creek/river crossings, geology, public land boundaries and land cover. This unique information is not to be found anywhere else.
The section overview map has each individual map page in that section outlined and shows a wide representation of the surrounding area. The overview also has an elevation chart and section overall mileage.
