Officials at Yosemite National Park say a massive amount of rock has fallen from a cliff, closing a hiking trail.
Officials say the rock crashed down from a cliff east of Wapama Falls. The rock broke into numerous boulders, crushing trees and sending up a small dust cloud.
Some 400 feet of the Rancheria Falls Trail were destroyed and park staff says it will remain closed for now. Park officials say hikers can still get to Wapama Falls starting at O'Shaughnessy Dam.
