For nearly 50 years and for generations of outdoor enthusiasts, the authoritative source on Colorado's mountains has been Guide to the Colorado Mountains. This latest edition compiles updated route descriptions for more than 1,500 hiking and climbing destinations -- peaks, passes, lakes, and trails-from the expert trip leaders of the Colorado Mountain Club. All the ranges are covered, with trails and peaks grouped by access and with new maps, photos, and a detailed index. A checklist ranks the peaks in order, and special sections cover climbing history, geology, backcountry use, recommended equipment, and much more.
