Yosemite National Park geologist, Greg Stock created an amazing view of El Capitan recently using a new type of mapping. "The movie was produced from terrestrial laser scanning (LiDAR) data collected from El Cap Meadow, with many millions of individually georeferenced points. The grayscale values relate to the reflectivity of the rock, which is why the North America diorite appears so dark relative to the surrounding granite.
Greg Stock is the first-ever Park Geologist at Yosemite National Park. He has B.S. and Ph.D. (U.C. Santa Cruz) degrees in geology and earth science, and was a researcher at the University of Michigan prior to accepting the job at Yosemite in 2006. Stock has a number of interesting articles about Yosemite rock fall and the park's geology.
