<p>The 21 chapters of <i>The Geology of Washington and Beyond</i>—an outgrowth of a geologic symposium—present the substantial advances in recent research on the geologic history of Washington State. The 34 contributors used new conceptual developments such as sequence stratigraphy, identification and matching of terranes, and neotechtonics, as well as breakthroughs in technology such as lidar mapping, paleomagnetism, and new methods of radiometric dating, to examine the fascinating geology of Washington State and beyond. Also included is geologic mapping in areas previously known only by reconnaissance. This book will influence resource management decisions, as well as disaster and land-use planning in the region. The introductory chapters make the book accessible for undergraduate courses in geology and to the general public.</p>
