Rapid 3D analysis of rockfalls in Yosemite. Yosemite National Park contains some of the world's most iconic landforms, including Half Dome, Yosemite Falls, and El Capitan. Although the cliffs of Yosemite Valley may appear static, rockfalls from these cliffs are common, with a rockfall occurring every four to five days on average. Rockfalls are key to shaping this iconic landscape but also pose risk to the four- to five-million visitors to the park annually. Source 2t.
