"Advances in Understanding and Mitgating Rockfalls in Yosemite National Park"

Presented by: Dr. Greg Stock- the Yosemite National Park Geologist

Yosemite National Park contains some of the world's most iconic landscapes, but rockfalls from the soaring cliffs pose considerable hazard and risk to the nearly five million annual visitors. This talk will summarize the geomorphic history of Yosemite Valley, review recent notable rockfalls, and describe how the application of new analytical tools such as structure-from-motion, airborne and terrestrial laser scanning, high-resolution photography, cliff monitoring, computer simulations of rockfall runout, and cosmogenic exposure dating provide quantitative data that improve our understanding of rockfalls and our ability to mitigate the resulting hazard and risk.

Greg Stock is the first-ever Park Geologist at Yosemite National Park. Greg has a B.S. in geology from Humboldt State University and a Ph.D. from UC Santa Cruz, and is a licensed geologist in California.  His research interests are primarily in geomorphology, and include glacial and fluvial erosion, geochronology, and hillslope processes such as rockfalls and debris flows. Greg has authored or coauthored more than 100 scientific papers and abstracts on Sierra Nevada geology, and is coauthor of the book "Geology Underfoot in Yosemite National Park'. He lives in Yosemite Valley with his wife and daughter.
