SEATTLE (NEWS1130) – Dozens of homes have been burned by a massive wildfire east of Seattle, and it’s still going strong. Investigators now believe it was caused by people.

At well over 11,000 hectares, the fire is 28 times the size of Stanley Park. A crew of 800 is scrambling to protect subdivisions near the city of Cle Elum and to prevent flames from jumping the I-90, about an hour and a half outside the Emerald City.

“[Investigators] are certain it was caused by human action of some sort but I don’t have any additional information on that,” explains Mark Marrow with Washington’s Department of Natural Resources. “It’s officially under investigation.”

Two counties are in a state of emergency, as at least 70 homes have burned. About 450 people remain evacuated and the fire is just 10 per cent contained.

“My concern is if my house is still there,” says Tim Marrin, who lives in the area. “[I] Loaded up the truck with a bunch of everything, we had as quick as we could and got out.”

Weather is now working in the firefighters’ favour, but they’re faced with difficult terrain.
