The slab of granite broke into many smaller pieces, ranging in size from 2 ft to 12 ft in diameter, which resulted in damage to the roadway. The entrance into the park at Arch Rock, along Highway 140, is closed until further notice. The time of reopening is unknown. Highways 41 and 120 are currently open with chain restrictions. There were no injuries associated with the rockslide.
Rockslides are a natural process in Yosemite National Park.
