TROUTDALE, Ore. (AP) — 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 wildfire-fighting, said 80 large fires were burning on 2,200 square miles (5,700 square kilometers) in nine Western states.
The 16-square mile (41-square kilometers) fire east of Portland forced hundreds of home evacuations. Embers from the fire drifted in the air across 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. Authorities say they believe the blaze, which started Saturday, was caused by a 15-year-old boy and friends using fireworks. They’ve identified a suspect but have made no arrests.
A 30-mile (48-kilometer) section of Interstate 84 was closed in both directions because of thick smoke and falling ash and because flames reached the roadway in some spots, said Dave Thompson, a spokesman for Oregon’s Department of Transportation.
“If it jumps the road, you’d be driving through a wall of flame,” he said.
People in Oregon covered their faces to shield themselves from the smoke and the ashes 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, Oregon, naturopathic clinic with Calla Wanser, who was wearing a red bandanna around her mouth to keep the ash out of her lungs.
A fast-moving wildfire in northern Utah swept down a canyon Tuesday — destroying structures, forcing evacuations and closing highways.
A least five homes 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 gusting at up to 40 mph.
Outside California’s Yosemite National Park, a wind-fueled fire made its way deeper into a grove of 2,700-year-old giant sequoia trees on Labor Day. Officials said the fire had gone through about half the grove but had not killed any trees.
Giant sequoias are resilient and can withstand low-intensity fires. The blaze burned brush and left scorch marks on some big trees that survived, said Cheryl Chipman, a fire information officer.
Elsewhere in Northern California, a fire destroyed 72 homes and forced the evacuation of about 2,000 people from their houses. The fire burned 14 square miles (36 square kilometers) in the community of Helena about 150 miles (240 kilometers) south of Oregon.
In Washington state, the U.S. Department of Defense has agreed to assign 200 active-duty soldiers to help fight a wildfire.
Civilian firefighting commanders said Tuesday the soldiers from Joint Base Lewis McChord, Washington, would undergo four days of training and then be sent to a complex of 14 wildfires in the Umpqua National Forest that have burned 47 square miles (120 square kilometers).
A wildfire burning near Mount Rainier National Park in Washington state grew to more than 29 square miles (75 square kilometers) and heavy smoke blanketed many cities in Washington state.
Mandatory evacuations were announced for the fire near Mount Rainier, including the Crystal Mountain ski resort.
The air quality in Spokane, Washington, was rated as hazardous. The National Weather Service says it was likely to get worse as wind shifts bring in smoke from fires in Canada, Montana, Oregon and Washington.
People in the region were advised to stay indoors.
In Oregon, people living in about 700 homes in and around the Columbia River Gorge have been forced to evacuate the area. Others have been warned to get ready as flames burn trees and brush in one of the state’s biggest tourist attractions.
Gov. Kate Brown visited the fire scene Tuesday as ash fell around her.
The fire spread 13 miles in 16 hours, pushed by winds overnight that ranged from 30 mph to 40 mph in tinder-dry conditions, Brown said.
“It looks like there has been a devastating impact on the gorge,” she said, speaking of the renowned Columbia River Gorge, famous for its hiking and spectacular vistas.
A total of 600 Oregon National Guard troops have been called up to fight more than a dozen blazes across Oregon, including a much larger blaze in southwest Oregon in a rural area along the California border.
There were heroic tales that came out Tuesday in the firefight near Portland. So far, no homes have burned and authorities credited the tireless work of fire crews through the night with that success.
Fire teams saved 58 homes as flames licked around them, working house-to-house in the rural communities of Dodson and Warrendale, said Lt. Damon Simmons, the Oregon State Fire Marshal spokesman. Teams also saved a historic lodge near Multnomah Falls.
“It was really a gutsy effort,” he said.
