A wall of mud, rock and debris crashed down hill in the Chelan County community of Stehekin about 11:45 p.m. Thursday, burying cars and trucks or sweeping them into Lake Chelan, and surrounding some businesses in a sea of mud and water.
The businesses affected were Discovery Bikes and Stehekin Reservations and Fly Fishing Shop, according to Ken Hires, Stehekin District interpreter.
A historic National Park Service storage shed at the Imus Cabin was filled with water and mud, the storage shed at the Lake House was damaged, and mud encroached on the public laundry building. There were no injuries, Hires said.
The Lake Chelan National Recreation Area is managed by the National Park Service as part of the North Cascades National Park.
