Stock, Greg M.
Greg Stock was born and raised in the Sierra Nevada just north of Yosemite, and he has explored the region by climbing on and caving in the region’s unique geology. These interests led him to pursue a bachelor’s degree in geology at Humboldt State University and a PhD in earth science at the University of California at Santa Cruz, where he studied the uplift and erosion of the Sierra Nevada. Greg is Yosemite National Park’s first-ever park geologist. He lives in Yosemite Valley with his wife, Sarah, and daughter, Autumn.
