Writing with verve and clarity, Mary Hill tells the story of the magnificent Sierra Nevada-the longest, highest, and most spectacular mountain range in the contiguous United States. Hill takes us from the time before the land which would be California even existed, through the days of roaring volcanoes, violent earthquakes, and chilling ice sheets, to the more recent history of the Sierra's early explorers and the generations of adventuresome souls who followed. The author introduces the rocks of the Sierra Nevada, which tell the mountains' tale, and explains how nature's forces, such as volcanic eruptions, earthquakes, faulting, erosion, and glaciation formed the range's world-renowned scenery and mineral wealth, including gold. For thirty years, the first edition of Geology of the Sierra Nevada has been the definitive guide to the Sierra Nevada's geological history for nature lovers, travelers, hikers, campers, and armchair explorers. This new edition offers new chapters and sidebars and incorporates the concept of plate tectonics throughout the text. * Written in easy-to-understand language for a wide audience. * Gives detailed information on where to view outstanding Sierra Nevada geology in some of the world's most beloved natural treasures and national parks, including Yosemite. * Provides specific information on places to see glaciers and glacial deposits, caves, and exhibits of gold mines and mining equipment, many from Gold Rush times. * Superbly illustrated with 117 new color illustrations, 16 halftones, 39 line illustrations, and 12 maps, and also features an easy-to-use, interactive key for identifying rocks and a glossary of geological terms.

This Special Issue comprises 12 papers from authors in 10 countries with new insights on the close coupling between magma as an energy and fluid source with hydrothermal systems for the primary control of magmatic behavior. Data and interpretation are provided on the rise of magma through a hydrothermal system, the relative timing of magmatic and hydrothermal events, the temporal evolution of supercritical aqueous fluids associated with ore formation, the magmatic and meteoric contributions of water to the systems, the big picture for the highly active Krafla Caldera, Iceland, as well as the implications of results from drilling at Krafla concerning the magma–hydrothermal boundary. Some of the more provocative concepts are that magma can intrude a hydrothermal system silently, that coplanar and coeval seismic events signal “magma fracking” beneath active volcanoes, that intrusive accumulations may far outlast volcanism, that arid climate favors formation of large magma chambers, and that even relatively dry rhyolite magma can rapidly convect and so lack a crystallizing mush roof. A shared theme is that hydrothermal and magmatic reservoirs need to be treated as a single system.
