    Collection Overview: NCALM Seed Project. PI: Valerie Zimmer, University of California Berkeley. The area of interest is defined by a quadrilateral polygon with an area of 35.1 km2, located in the grounds of the Yosemite National Park, specifically the Half Dome and the Yosemite Valley. The polygon is located approximately 127 km east of Modesto, CA and 110 km north of Fresno, CA. The data were collected for rock fall studies in the Yosemite National Park using seismic, acoustic, and Lidar data.
