Geology of Southeast Alaska


Book Description

The most powerful forces on earth have shaped the landscape of Southeast Alaska. Scientists and visitors from around the world trek north to experience wild rivers, powerful glaciers, and breathtaking mountain peaks. Now, for the first time, a handy guide to the region is available. Complete with color illustrations revealing millions of years of geological history and in-depth descriptions of Sitka, Juneau, and Glacier Bay, Geology of Southeast Alaska is essential reading for anyone fascinated by rock and ice in motion. Written by a geologist with over twenty-five years of experience in the north, Geology of Southeast Alaska will entertain and inform with abundant photographs and detailed drawings. Whether you want to understand the forces that shaped the state of Alaska, or you want to learn the basics of glacial movement, this compact, authoritative book is for you.




Roadside Geology of Alaska


Book Description

The biggest US state is full of superlatives. Denali, the highest peak in North America at 20,320 feet, is still rising, pushed upward as a tectonic plate collides from the south. The collision has also created huge mountains along Alaska�s Gulf Coast, where humid coastal air has produced the largest subpolar icefield in North America. The exceptional heights of Alaska�s mountains are mirrored below sea level by the 22,377-foot-deep trench of the active subduction zone along Alaska�s southern shore. Earthquakes associated with the subduction zone shake Alaskans frequently, and the magnitude 9.2 earthquake in 1964, with its epicenter in Prince William Sound, was one of the largest seismic events ever recorded. Such an active geologic setting calls for an updated edition of this popular roadside geology guide. Since the first edition was published in 1988, volcanoes have erupted, faults have ruptured, glaciers have retreated, permafrost has thawed, and geologic interpretations have changed. Author Cathy Connor discusses the latest findings as she guides readers along the roads of Alaska and adjacent parts of British Columbia and the Yukon. In addition to roads and national parks, the book covers the �boatside geology� of Alaska, including the fjords of southeast Alaska, islands in the Bering Sea, and the Tatshenshini River. Roadside Geology of Alaska is a must-have for any Alaska rock enthusiast.










Uncovering Submerged Landscapes


Book Description

Earlypeoples migrating to the Americas via the coastal migration route would havetravelled through southeast Alaska during periods with lower sea levels. Theresidues of where they lived, hunted and gathered are on the now submergedcontinental shelf of southeast Alaska. A GIS model, two years of marinegeophysical survey (including side scan sonar, sub-bottom profiling andmultibeam sonar) and minimal subsurface testing have allowed the author torefine the methods for locating submerged archaeological sites buried on thecontinental shelf. The environment is reconstructed in 500-year intervals, andthese intervals are used to create a predictive model for each time periodusing inductive and deductive methods. The final model combines the intervalmodels for a final prediction of probable archaeological sites within theregion.

The Geology of Florida


Book Description

"A significant contribution to our knowledge of Florida geology. . . . A state-of-the-art volume that will serve as a model for other university presses to follow."--Paul A. Thayer, University of North Carolina, Wilmington "A marvelous and timely overview of the geology of Florida . . . assembled by some of the state's best geoscientists."--Henry T. Mullins, Syracuse University The first comprehensive geology of the state of Florida published in over thirty years, this volume brings together leading geoscience authorities from academia, state and federal geological surveys, and private industry in a liberally illustrated, up-to-date summary and analysis. Early chapters introduce the origin and development of the unique landscape of the Florida peninsula and panhandle. Succeeding chapters cover geomorphology, stratigraphy, plate tectonics, petrology, geochemistry, hydrogeology, vertebrate and invertebrate paleontology, geologic history, economic geology, coastal and marine geology, and environmental geology. With the longest coastline of any state except Alaska and a geology noted for its rich fossil record and abundance of living coral reefs, mineral deposits, springs, and sinkholes, Florida's identity--past, present, and future--is linked intrinsically to its landscape. The definitive reference for that landscape, The Geology of Florida illustrates the importance of basic geological research and its application to issues facing a society that places increasing demands upon its physical world. Anthony F. Randazzo is professor of geology at the University of Florida and author of numerous articles in Sedimentary Geology, Journal of Sedimentary Petrology, American Scientist, and others. Douglas S. Jones is curator and chair of the Department of Natural Sciences at the Florida Museum of Natural History and author of numerous articles in Nature, Geology, Science, and others.
