"Applying the fundamental principles of geology to the rocks of the Great Basin, we now have indisputable evidence that the region, however lofty and dry it may appear today, lay almost continuously beneath the waters of vanished oceans for more than 400 million years. The bed of this ancient ocean, where enormous amounts of mud, muck, and sand accumulated during the immense period of inundation, is the subject of this book: it is the Sagebrush Seafloor"--
Note:
Many people appreciate the stunning vistas of the Great Basin desert; understanding the regions geological past can;provide a deeper way to know and admire this landscape. In The Great Basin Seafloor, Frank DeCourten immerses;readers in a time when the Basin was covered by a vast ocean in which volcanoes exploded and sea life flourished.Written for a nontechnical audience, this book interprets the rock record left by more than 500 million years of oceanic activity, when mud and sand accumulated and solidified to produce today Great Basin across parts of modern Utah, Nevada, and California. DeCourten deciphers clues within exposed slopes and canyons to reconstruct the vanished seafloor and its volcanic events and examines fossils to reveal once-thriving ancient marine communities. Supplemental material is available online to serve as a field guide for readers wishing to explore this ancient ocean themselves as they travel through the region.
