Article Photos: APNewsBreak: Rock risk forces Yosemite closures 1/4

  FILE - In this Monday, Oct. 20, 2008 file photo, restriction tape blocks an area at Curry Village in Yosemite National Park, Calif., after a boulder fell during a rock slide. Falling boulders are the single biggest force shaping Yosemite Valley, one of the most popular tourist destinations in the nationâs system of national parks. Now large swaths of popular haunts deemed unsafe are closing as officials acknowledge they knew for more than a decade ago that unsuspecting tourists were being lodged in harmâs way. On Thursday, June 14, 2012, the National Park Service will announce that potential danger from the unstable 3,000-foot-tall slab of granite known as Glacier Point, a picturesque promontory that for decades has provided a dramatic backdrop to park entertainment events, will leave uninhabitable large parts of Yosemite Valleyâs most popular lodging areas.
