From the time the PCT leaves the Mexican border, until it reaches Canada, it has traveled 2,650 miles through 24 national forests, 37 wilderness areas, and 7 national parks. In Pacific Crest Trail: Northern Cali-fornia, you'll meet up with the PCT in Yosemite National Park's Tuolumne Meadows, then hike, climb, descend, and switchback your way to the Oregon border. You'll discover rivers, peaks, forests, meadows, fascinating geological formations, and other natural wonders. You'll pass through Emigrant, Desolation, and Marble Mountain wildernesses; Trinity Alps and Lassen National Park; and, you'll see Lake Tahoe, Burney Falls, Mt. Shasta, and Castle Crags. This book helps you locate the PCT and side-trips, find water sources, and access resupply routes. Jeffrey P. Schaffer also describes the rich geological and natural history of these mountains. Information on camping, permits, and the best seasons to go is provided along with updated maps.
