Rock strength properties of granitic rocks in Yosemite Valley, Yosemite National Park, California

A significant rock fall of 9,811 cubic meters from El Capitan's southeast face in Yosemite Valley on September 28, 2017, highlighted the need for detailed analysis of granitic rock strength properties. The study, conducted by Collins et al. (2020), focused on understanding the mechanical behavior of these rocks to assess their stability and potential hazards. Researchers employed a combination of field observations, laboratory tests, and numerical modeling to evaluate factors influencing rock fall events. Their findings provide critical insights for risk assessment and management in Yosemite National Park, where granitic rocks are prone to large-scale collapses due to geological and environmental stresses.
