YOSEMITE NATIONAL PARK, Calif. - Falling boulders are the single biggest force shaping Yosemite Valley, one of the most popular tourist destinations in the national park system. Now swaths of some popular haunts are closing for good after geologists confirmed that unsuspecting tourists and employees were being lodged in harm's way.
On Thursday, the National Park Service announced that potential danger from the unstable 3,000-foot-tall Glacier Point, a granite promontory that for decades has provided a dramatic backdrop to park events, will leave some of the valley's most popular lodging areas permanently uninhabitable.
"There are no absolutely safe areas in Yosemite Valley," said Greg Stock, the park's first staff geologist and the primary author of a new study that assesses the potential risk to people from falling rocks in the steep-sided valley. The highest-risk area is family-friendly Curry Village, which was hit by a major rockfall several years ago.
