Living in the Plate Boundary and Through the Ice Ages

The geology and landscapes of California are the results of a long history of plate tectonic interactions. The majestic granite walls of Yosemite, the rich agricultural soils of the Central Valley, and the wild-colored rocks of the Coast Ranges all reflect a long history of subduction. Our present beloved topography of dramatic mountains and sweet valleys reflect the evolution of the San Andreas plate boundary. In turn, all these features have been modified by sea level and climate changes during the ice ages. Using maps, landscape images and computer animations, Atwater will describe and explain all these geo-treasures.
