A firefighter was killed in Idaho and another firefighter in Oregon suffered burns after she had to deploy her emergency fire shelter as wildfires continued raging across the western United States.

Anne Veseth, a 20-year-old firefighter, was killed Sunday after she was struck by a falling tree while working on a fire near Orofino in northern Idaho, the U.S. Forest Service said.

"The Forest Service is devastated by the loss of one of our own," Forest Supervisor Rick Brazell said.

The incident is under investigation. Veseth, of Moscow, Idaho, was in her second season working as a firefighter. There are 12 active blazes across the state.

In southeastern Oregon, a firefighter was forced to crawl into her emergency shelter in an area overrun by swirling winds filled with fire. She was treated at a Nevada hospital Sunday for minor burns to a leg and forearm and minor smoke inhalation. As a precaution, she was being sent to a burn center in Salt Lake City for evaluation, fire spokesman Chris Rose said.

The rest of her 20-person federal crew made it to a safety zone. They have been pulled off the fire as that incident is under investigation.

The Holloway Fire has so far burned 653 square miles (1,691 square kilometers) in remote and rugged terrain straddling the Oregon-Nevada border. On the Nevada side, five ranches were evacuated Sunday evening in the Kings River Valley.

In Utah, firefighters made gains throughout the weekend on several blazes burning across the state as more mild temperatures coupled with sporadic rain and humidity helped with containment.

The lightning-sparked Faust Fire that had threatened a herd of wild horses and shut down the historic Pony Express Road in Utah's west desert consumed about 34 square miles (88 square kilometers), but was expected to be fully contained late Monday, said state fire spokeswoman Cami Lee.

Meanwhile, crews in Northern California on Monday were making progress against an aggressive wildfire that has grown to more than 9 square miles (23 square kilometers).

After it forced the evacuation of nearly 500 homes since it began Sunday, officials allowed residents to return late Monday, said Daniel Berlant, a spokesman for the California Department of Forestry and Fire Protection.

Three buildings were destroyed and two people were treated for minor injuries. The blaze, which started as two separate fires, but was being treated as one incident, was 25 percent contained.

Several other fires were raging elsewhere In Northern California, the largest of which covers 55 square miles (142 square kilometers) near the Seneca and Rush Creek communities in Plumas National Forest.

In Southern California, two fires sparked by lightning from Sunday thunderstorms continued to burn out of control Monday in the wilderness.

To the north, strong winds fanned a blaze in central Washington state that destroyed at least two dozen structures Monday.
