Those who designed the National Geographic Trails Illustrated topographic maps understand what hikers, backpackers, travelers, and explorers need. The company's Wyoming Rocky Mountain Maps include everything you need to stay on track, well beyond the usual topographic markings. In addition to trails, campgrounds, river crossings, and points of interest, these waterproof and tear-resistant maps provide info on wilderness travel, safety, and local flora and fauna. Includes UTM grids for use with your GPS unit.
