A large rockslide on Monday afternoon is going to keep the Arch Rock Entrance at Yosemite National Park closed at least throughout the weekend.
About 4,000 tons of rock broke away from the cliff adjacent to El Portal Road, which is an extension of Highway 140. The slab slid down the cliff and broke into many pieces after hitting a ledge. The debris fanned out over 1,000 feet, according to a release from the National Park Service.
One-third of the debris landed on El Portal Road. About 150 feet of the road is covered with 15-20 feet of rocks, with the largest boulder weighing 130 tons, according to the NPS.
The road itself sustained damage, as well as the retaining wall.
Yosemite National Park staff will be assessing the road and surrounding area at least until the weekend, . After staff finish the assessment, crews will begin to remove the debris and repair the road.
There is no estimate for when the road will reopen.
