A comprehensive geologic view of the natural processes that have created, and are still creating, the stunning terrain we know as Yosemite.

While visiting more than twenty-seven amazing sites, you�ll discover why many of Yosemite�s domes shed rock shells like onion layers, what happens when a volcano erupts under a glacial lake, and why rocks seem to be almost continually tumbling from the region�s cliffs.

“Get your head into the clouds with Aerial Geology.” —The New York Times Book Review Aerial Geology is an up-in-the-sky exploration of North America’s 100 most spectacular geological formations. Crisscrossing the continent from the Aleutian Islands in Alaska to the Great Salt Lake in Utah and to the Chicxulub Crater in Mexico, Mary Caperton Morton brings you on a fantastic tour, sharing aerial and satellite photography, explanations on how each site was formed, and details on what makes each landform noteworthy. Maps and diagrams help illustrate the geological processes and clarify scientific concepts. Fact-filled, curious, and way more fun than the geology you remember from grade school, Aerial Geology is a must-have for the insatiably curious, armchair geologists, million-mile travelers, and anyone who has stared out the window of a plane and wondered what was below.

Glaciers in sunny California? Many people will be surprised to learn that there are several hundred in this state, ranging in size from the impressive Whitney Glacier on Mt. Shasta and the Palisade Glacier in the Sierra Nevada to tiny glacierets. While California's glaciers are small compared to those in the northern Rockies or the European Alps, each one is interesting and some are suitable for exploring. Also of note is the fact that Ice Age glaciers carved California's most spectacular mountain scenery—the High Sierra was glaciated several times and glacial landforms are prominent features of the Sierran landscape today. Bill Guyton summarizes the history of the discovery of Ice Age glaciation and modern-day glaciers in California, as well as the development of modern ideas about the state's glacial history. He describes the controversy about the origin of Yosemite Valley and quotes from the colorful accounts of early mountain explorers such as John Muir, Josiah Whitney, and François Matthes. His book provides a primer on glaciers and glacial landforms, a glossary of technical terms, helpful illustrations, and a 100-mile Sierra field trip guide for readers who want to see glaciers and glacial features for themselves. Glaciers of California will make any visit to the mountains more interesting, whether one is carrying a camera, crampons, or a fishing pole.
