Not published yet. This book is full of wild, hard-core tours in the High Sierra backcountry. Covers Sierra Nevada between Yosemite and Lake Tahoe. Many tours are geared for alpine backcountry skiers. Instead of this book, however, I recommend Ski Tours in Southern California , which is newer and covers a lot more places to ski.
Tours are well described and mapped and includes interesting background information.
This book has interesting sections on skiing history and how to ski, however, it's not a guidebook. This book broadly describes areas to ski and lodging, but doesn't describe any ski trail and has no ski maps. I recommend Marcus Libkind's books instead. Ski Touring in California 1st. A classic book by an expert guide, who still guides out of Tahoe.
