A tanker plane that disappeared in eastern Oregon while fighting one of the many wildfires spreading across several Western states has been found, and the pilot on board is dead, authorities said Friday.

A Grant County Search and Rescue team located the aircraft Friday morning and confirmed the death, said Lisa Clark, a Bureau of Land Management information officer for the Falls Fire. The single-engine tanker, a small and nimble plane that looks like a crop duster, was located in steep, forested terrain on Friday morning after the search was suspended at nightfall the day before, Clark said.

The plane contracted by the U.S. Bureau of Land Management went missing Thursday. The Falls Fire, near the town of Seneca on the edge of the Malheur National Forest, has grown to 219 square miles and is 55% contained, the government website InciWeb shows.

Thomas Kyle-Milward, spokesperson for Northwest Incident Management Team 8, said authorities received a report of a missing aircraft around 6:50 p.m. Thursday. The pilot was the only person on board.

Climate change is increasing the frequency of lightning strikes as the region endures recording-breaking heat and bone-dry conditions. More than 110 active fires covering 2,800 square miles were burning in the U.S. on Friday, according to the National Interagency Fire Center.

Alleged fire-starter arrested

In California, more than 130 structures have been destroyed and thousands more remain threatened by the state's largest active wildfire. The Park Fire started Wednesday when a man pushed a burning car into a gully in Chico and then calmly blended in with others fleeing the scene, authorities said.

Ronnie Dean Stout, 42, of Chico, was arrested early Thursday and held without bail pending a Monday arraignment, officials said. There was no immediate reply to an email to the district attorney asking whether the suspect had legal representation or someone who could comment on his behalf.

By Friday morning, the fire was completely uncontained after burning more than 257 square miles across the Sierra Nevada foothills above the city of 100,000. About 4,000 residents in unincorporated areas of Butte County and 400 residents of Chico were ordered to evacuate, Butte County Sheriff Kory Honea said late Thursday. Two minor injuries were reported, 134 structures were destroyed and some 4,200 were threatened.

“The fire quickly began to outpace our resources because of the dry fuels, the hot weather, the low humidities and the wind,” Butte County Fire Chief Garrett Sjolund said.

The Park Fire was burning to the northwest of Paradise, the Butte County community where in 2018 the notorious Camp Fire killed 85 people and incinerated thousands of homes, becoming California’s deadliest and most destructive wildfire. Butte County Sheriff Kory Honea said he wanted “to express regret and frustration by the fact that we are here once again.”

World Heritage site devastated

The most damage so far has been to the Canadian Rockies’ Jasper National Park, where a fast-moving wildfire forced 25,000 people to flee and devastated the park’s namesake town, a World Heritage site.

Oregon still has the biggest active blaze in the United States, the Durkee Fire, which combined with the Cow Fire to burn nearly 630 square miles. It remains unpredictable and was only 20% contained Friday, according to the government website InciWeb.

In Idaho, lightning strikes sparked fast-moving wildfires and the evacuation of multiple communities, including one where a man drove past a building and trees engulfed in flames as a tunnel of smoke rose over the roadway.

Videos posted to social media include a man who said he heard explosions as he fled Juliaetta, about 27 miles southeast of the University of Idaho’s campus in Moscow. The town of just over 600 residents was evacuated Thursday just ahead of roaring fires, as were several other communities near the Clearwater River and the Nez Perce Tribal Hatchery Complex, which breeds salmon in an effort to supplement dwindling numbers of the keystone species.

“This a rough one, this sequence of fires,” said Robbie Johnson, a public information officer with the Idaho Department of Lands. “We’re using everything we’ve got — when you have those additional fire starts in an area, you have to say, ‘this needs aircraft over here, and over here,’ and make those rough decisions about the attack. We’ve got really smart people working on that.”

There’s no estimate yet on the number of buildings burned in Idaho, nor is there information about damage to urban communities, Johnson said Friday morning.

More blazes

Elsewhere in California, about 1,000 people were displaced Thursday by the lightning-sparked Gold Complex fires, which burned nearly 5 square miles of brush and timber in the Plumas National Forest in California, near the Nevada line and about 50 miles northwest of Reno. Some evacuations were lifted Friday, when the fire was at 11% containment.

And in inland Southern California, firefighters battled a small fire that erupted Thursday afternoon in hills just above the Riverside County city of Lake Elsinore. The Macy Fire was 15% contained early Friday, with one unspecified structure destroyed. In rural northern San Diego County, containment of the 3-day-old Grove Fire jumped to 25% after a day of minimal growth.

The National Interagency Fire Center said more than 27,000 fires have burned more than 5,800 square miles in the U.S. this year, and in Canada, more than 8,000 square miles have burned in more than 3,700 fires so far, according to its National Wildland Fire Situation Report issued Wednesday.
