Rock falls from Glacier Point above Camp Curry, Yosemite National Park, California
Wieczorek GF and Snyder JB. 1999. Rock falls from Glacier Point above Camp Curry, Yosemite National Park, California. U.S. Geological Survey (USGS) Open-File Report. 99-385. USGS. Reston, VA
A series of rock falls from the north face of Glacier Point above Camp Curry, Yosemite National Park, California, have caused reexamination of the rock-fall hazard because beginning in June, 1999, a system of cracks propagated through a nearby rock mass outlining a future potential rock fall. If the estimated volume of the potential rock fall fails as a single piece, there could be a risk from rock-fall impact and airborne rock debris to cabins in Camp Curry. The role of joint plane orientation and groundwater pressure in the fractured rock mass are discussed in light of the pattern of developing cracks and potential modes of failure.
