Book excerpt: Features 932 routes including dozens of new routes and a new chapter on the Grand Traverse All-new aerial photography with detailed route overlays This fourth edition of A Climber’s Guide to the Teton Range--years in the making—includes 932 routes on more than 235 peaks and canyon walls. For each route, longtime Teton climbing ranger Renny Jackson supplies difficulty classification, first ascent information, and access to the route, and, as needed, also includes approach considerations, route and/or pitch details, and route of descent. He notes the estimated time needed for the climb and any additional protection needs. Cross-references for each route shown on the topographic figures help climbers quickly find the route details they need. Readers will find a greatly expanded section on the history of climbing in the Tetons along with updated information about geology, climatology, preparation, regulations, and ethics. Jackson also covers possible traverses and enchainments (linking up several routes). A new section explaining route descriptions, maps, and difficulty ratings enhances this edition’s usability, and a complete list of Jackson’s favorite climbs rounds out this essential guide.
