The best backcountry skiing in the Eastern Sierra is centered on the town of Mammoth Lakes, and Dan and Nate have made sure that nothing is left out of the broad area covered in the book, extending from Tioga Pass in the north to Bishop Creek in the south. From the backyard runs on the Mammoth Crest to the roadside accessible Tioga Pass, and the epic wilderness peaks like Mt. Tom and Laurel Mountain, this guide serves as both the ultimate introductory resource and the experienced hard-man's hit list.

The authors give a written description for each approach and descent along with useful statistics for gauging conditions and seriousness, including the slope, aspect, and angle, vertical gained and mileage of the approach, and a seriousness rating. The extensive use of color action and peak shots makes this book an incredible exposé of the Sierra in winter. Regardless of skiing ability, any mountain enthusiast will drool over this book. It will set the bar for generations of backcountry ski and mountaineering guidebooks to come.
