Dozens of wildfires

in the Western U.S. send smoke into major cities.

TROUTDALE, Ore. — A growing Oregon wildfire covered parts of Portland’s metropolitan area Tuesday with ash and forced the shutdown of a lengthy stretch of highway through the state’s scenic Columbia River Gorge.

It was one of dozens of wildfires burning in western U.S. states that sent smoke into cities from Seattle to Denver — prompting health warnings and cancellations of outdoor activities for children by many school districts.

The National Interagency Fire Center in Boise, Idaho, a federal agency that coordinates wildland firefighting, said 80 large fires were burning on 2,200 square miles in nine Western states.

The 16-square mile fire east of Portland forced hundreds evacuations. Embers from the fire drifted over the Columbia River, sparking blazes in neighboring Washington state.

The wildfire grew rapidly late Monday and overnight, giving authorities just minutes to warn residents on the Oregon side of the river to leave their homes.

A closure of one section of Interstate 84 because of thick smoke and falling ash was extended 50 miles east of Portland because flames reached the roadway, said Dave Thompson, a spokesman for Oregon’s Department of Transportation.

People in Oregon covered their faces to shield themselves from the smoke and the ash falling on them.

“You can’t really stand outside without getting rained on” by ash, said Joanna Fisher as she walked to work at a Troutdale, Ore., naturopathic clinic.

Elsewhere, a fast-moving wildfire in northern Utah swept down a canyon Tuesday morning — destroying structures, forcing evacuations and closing highways.

A least one home burned and more than 1,000 people were evacuated as high winds fed the flames in the canyon north of Salt Lake City. Thick black smoke closed parts of two highways as firefighters struggled to fight the blaze fueled by winds gust at up to 40 mph.

A fire in Montana’s Glacier National Park emptied its busiest tourist spot as wind gusts drove the flames toward the doorstep of an iconic lodge.
