A five-acre fire destroyed three recreational cabins and caused major structural damage to a private residence on the north shore of Lake Wenatchee, about 14 miles north of Leavenworth.
Photos from a homeowner in the area show flames coming dangerously close to their house.
Ross Kavanaugh managed to escape the flames, leaving his summer home behind.
"I've never seen anything like it, so sudden," he said. "It was like a wall of fire."
He said the old house was like something out of Norman Rockwell painting.
"It had braided rugs, pines and an old 1950s stove," he said. "There's absolutely nothing left."
The North Shore Fire was reported Friday evening and the cause is under investigation.
Fire managers reported Saturday afternoon that the fire was 35 percent contained and that more than 100 firefighters were involved in fighting the fire. Two helicopters were staged at the nearby Fish Lake Airstrip and ready to provide assistance.
Firefighters spent much of Saturday reinforcing containment lines and extinguishing hot spots within the fire perimeter. Firefighting efforts were being hampered by a large number of dead standing trees in the area.
North Shore Road remained closed Saturday afternoon for public and firefighter safety west of Brown Road to the old ranger station on the lake's north shore. Lake Wenatchee Highway, or State Highway 207, remained open.
The Chelan County Sheriff's Office has advised residents near the fire they are under a level-1 evacuation notice that advises them they should be aware of the danger that exists and monitor local media outlets for further information.
