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.

You can read more about Atwater and her background here. In the 70s, she wrote about the origins and growth of the San Andreas fault, and contributed to our current understanding of a then nascent idea — it sometimes seems hard to believe that plate tectonics is a new idea! For a little teaser of what she has to show — see the video below…
