Lake Tahoe, a national treasure, is one of the most popular vacation destinations in the United States. This book, based on over 25 years' research by the author and collaborators, reveals the geologic story behind Tahoe's magnificent scenery and landscapes, guides the visitor on journeys (day trips) around the lake, and explains what you will see and explore on all routes in the Tahoe basin, blending in important details of geology and history. The Tahoe tsunami theme is a big story, a lot of it presented here for the first time. There are many new insights on world-famous locations including Emerald Bay, Cave Rock, Stateline Point, and South Lake Tahoe. Virginia City and the Comstock Lode are also explored because the Tahoe basin and Virginia City together greatly influenced U.S. history. This book reveals that every viewpoint at Lake Tahoe has an important story to tell. Photography is by the author, except where noted.
