A derivative of the comprehensive John Muir Trail by Sierra expert Elizabeth Wenk, this data book is perfect for the weight-conscious hiker. A brief introductory section provides planning data, including information on permits, trailhead transport, and food resupplies. This is followed by on-the-trail information, including custom-made topo maps, elevation profiles, data tables, and labeled panoramas from prominent passes. There are tables for trail junctions, nearly 300 campsites, ranger stations, food-storage lockers, and lateral trails accessing the JMT. For detailed information on planning for your trip, considerations for hiking in the Sierra Nevada, or a trail description, those are only available in the comprehensive John Muir Trail book.
