Alaska shows off its dynamic difference--terra is not necessarily firma--with mountains growing higher, land moving frequently, volcanoes erupting, glaciers receding, and permafrost thawing in Connors Roadside Geology of Alaska, which includes information from new technologies and more research available since the previous edition in 1988. He provides a summary of Alaskas geologic experience over the eons, finds interesting developments in geologic research, and introduces wild and often unexpected geologic stories. Geologic maps are included to provide readers with an idea of terrane boundaries, major faults, and the ages and types of rock. Not your mothers terrain, terrane is fragments of a continent, ocean crust, or volcanic arc, or disrupted combinations of these, that share a common geologic history and have often traveled far from where they originated. There are nine sections: geologic history of Alaska; southeast Alaska and coastal British Columbia; Guides to southeast Alaska and coastal British Columbia; south-central Alaska and the Aleutians; guides to south-central Alaska; interior Alaska and adjacent parts of the Yukon; guides to interior Alaska and adjacent parts of the Yukon; Arctic Alaska; guides to Arctic Alaska. There is a glossary, references, and many illustrations. Annotation 2015 Ringgold, Inc., Portland, OR (protoview.com)
