Authorities say the wildfire burning in Oregon's Columbia River Gorge about 75 miles east of Portland has destroyed a home, damaged two others and is threatening 740 more.
Residents of more than 140 homes have been told to evacuate and nearly 600 households have been put on alert in the community of Rowena near The Dalles.
The official information page for the Rowena Fire on Facebook says the fire covered about 5 square miles by Friday morning with a forecast of low humidity and high winds increasing the danger.
The fire started Tuesday in brush and forced hundreds of people to flee. Many were allowed to return home Thursday, but the flames continued to spread despite the efforts of more than 400 firefighters.
