This recent US Geological Survey Report, Rock falls from Glacier Point above Camp Curry, Yosemite National Park, California, by Gerald F. Wieczorek and James B. Snyder, provides a geological analysis of the potential for future rock falls onto Camp Curry from Glacier Point. More specifically, "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." Text is complemented with excellent graphics including high-quality photographs.
