The fully updated fourth edition of Mt. Shasta, by Andy Selters and Michael Zanger, is the most comprehensive and detailed guide and overview to a large, varied, historic, and coveted mountain for climbing and skiing. The guide offers extensive detail on dozens of trips both on the mountain and in its surroundings, including weather, climbing and skiing conditions, amenities, and history. A special extra is a guide to Shasta’s superb circumnavigation at timberline, pioneered by John Muir, that is often referred to as one of the best off-trail hikes in the Northwest. The book also comes with a topographic map showing all mountain routes and variations.
