Geology/Plate Tectonics: Have you ever wondered how and why mountains form, why there are earthquakes, or why there are volcanoes? At this talk we will discuss Plate Tectonics which is the theory that rigid portions (plates) of the surface of the earth move with respect to each other. Because of this motion, many topological features such as mountains, volcanos, and faults on the surface of earth can be understood.
Inside the beautiful Galena Creek Visitor Center, 50 minutes of amazing photos and diagrams from our own rock star, Marvin Katz, drawing on his life long career spanning mining, petroleum and environmental geology will be followed by a brief outdoor discussion of local rock and related mountain building processes (orogeny). Consider bringing a cool drink and hat to supplement the sunglasses for this part.
