Yosemite National Park road crews have begun clearing debris caused by a rockfall on Thursday morning, January, 7, at 5:45 a.m. that closed the El Portal Road (Highway 140) in Yosemite National Park. The rockfall triggered several large boulders and debris to block access to Yosemite Valley via Highway 140. Park staff and U.S. Geological Survey (USGS) staff assessed the site earlier today and deemed it safe for park personnel to begin removing the rocks and debris. http://www.nps.gov/yose/learn/news/yosemite-national-park-begins-clearing-rockfall-debris-on-highway-140.htm
