A rock slide Tuesday in the Staircase Falls area of Yosemite Valley destroyed an unoccupied tent cabin, a park spokesman said.

There were no injuries in the 2:30 p.m. event, but the area immediately around the slide in Curry Village was evacuated.

The 1,020-foot Staircase Falls cascades from Glacier Point to a meadow just east of Curry Village, which is also home to the winter ice rink and amphitheater.

A park helicopter was dispatched to "make sure the origin is stable," said ranger Erik Skindrud.

A rock fall in the same area a year ago also resulted in no injuries, Skindrud said.
