This work is designed to help the non-geologist to understand the geological mechanisms which formed the Sound and southcentral Alaska and to help him identify common rock types. Basic geological concepts, an introduction to plate tectonics and terrane theory are covered. The field guide section describes 124 sites in the Sound where one can observe typical rocks and formations with special emphasis on the Sound's mines and mining history.
