A rockfall in the Hetch Hetchy area of Yosemite National Park has closed the trail to Rancheria Falls east of Wapama Falls.
According to the National Park Service, at approximately 1:30 p.m. on March 31, a large rockfall occurred from the cliff just east of Wapama Falls above the Hetch Hetchy reservoir. The trail was closed just east of the Wapama Creek footbridges for safety purposes. Boulders are preventing access beyond Wapama Falls to park visitors. No visitors were injured in the rockfall.
Roughly 16,000 tons of rock fell from approximately 500 feet above the base of the cliff. Rock debris hit the slope below the cliff, breaking into numerous boulders, crushing trees, and creating a small dust cloud. Fresh boulders completely covered the slope, and many boulders tumbled into the reservoir. Roughly 400 feet of the Rancheria Falls Trail was destroyed in the main impact area.
Hikers can still access Wapama Falls starting from O’Shaughnessy Dam. The trail to Rancheria Falls just after Wapama Falls will be closed until further notice.
