7The Pocket PCT contains an elevation profile and important landmarks on the Pacific Crest Trail (PCT). Each chapter begins and ends at a common resupply location. The elevation profile is broken into ten-mile segments, showing the trail's elevation in feet. Water sources, landmarks, roads and trails are indicated above the elevation profile line. Additional important town information is also provided. The mileages are compatible with Halfmile maps and the Guthook's Pacific Crest Trail Guide app (iPhone & Android). The book is lightweight (4.9 ounces), compact (5 by 8 inches) and just over a quarter inch thick.
