Book excerpt: The water is so clear and filled with so much color, it's like splashing liquid glass. Lake Tahoe is legendary for its crystal-clear turquoise waters. Even Mark Twain commented on its "dazzling" and "brilliant" clarity. This is the first book of underwater photography from America's most famous lake, which stretches over 191 square miles on the California-Nevada state line. The camera lens captures bizarre and fluid shapes that form faster than the eye can see or the mind can comprehend. More than 180 images show Tahoe's breathtaking submarine scenery, from its teal shallows, rounded boulders, and swirling compositions to the surreal still lifes in its clear, quiet depths. For everyone who loves Lake Tahoe, the images are a lasting reminder of its singular beauty--and a call to help preserve its health.
