PRICE -- Several wildfires burning across Utah have forced hundreds to flee their homes, destroyed dozens of structures and briefly prompted the closure of a part of Zion National Park.
Firefighters worked feverishly Thursday to gain control of the fires, with one blaze in the central part of the state burning with little containment after destroying at least 56 structures, authorities said.
Officials couldn't immediately say how many of the burned structures were homes but they expected the number to rise considerably as they continue their assessment of the fire-ravaged area between Fountain Green and Fairview and north across the Utah County line.
The Wood Hollow Fire in Sanpete County had grown to about 46,000 acres, or 72 square miles, by Thursday. Three firefighters suffered minor injuries, authorities said.
The blaze is the largest of several burning in Utah. Officials re-opened U.S. 89 Wednesday and an evacuation order for the roughly 1,200 residents of Fairview was lifted, said Mayor Jonathan Benson.
However, authorities said they're still concerned about winds picking up and hampering the containment effort, which sat at about 15 percent.
Authorities still have not released the identification of a body found Tuesday morning in an evacuation zone. They also haven't released any details on exactly where the remains were found.
Elsewhere in the state, the New Harmony Fire near St. George started Wednesday afternoon and had grown to 2,000 acres by Thursday. Authorities said it was 60 percent contained.
Fire officials said eight structures have been destroyed and an undetermined number of residents near Bumblebee have fled their homes, while evacuation orders elsewhere around the blaze had been lifted.
The fire was burning about three miles north of Zion National Park, prompting park officials to briefly close a canyon Wednesday popular with hikers known as the Kolob section. Park officials re-opened the area on Thursday.
Officials said there was no containment on the Seeley Fire, which has forced evacuations in Clear Creek, Hiawatha, Wattis and Scofield, including about 100 girls at a camp and a group of Boy Scouts.
That blaze has burned roughly 15,000 acres, Manti-La Sal National Forest spokeswoman Rosann Fillmore said Thursday.
"It's hard to access and hard to fight. We're getting some air support," she said. "The smoke is dumping into Price and Helper."
The Church Camp fire, burning about 20 miles south of Duchesne, has charred about 5,200 acres and was 5 percent contained Thursday.
Officials have evacuated about 30 people in nearby Argyle Canyon. The blaze has destroyed about 12 structures.
The 17,000-acre Clay Springs Fire near Nephi forced the evacuation of the small communities of Oak City and Fool Creek. The number of evacuees wasn't immediately clear, but officials said the blaze was threatening about 100 structures and one cabin had been burned as of Thursday.
Fire spokesman Jason Curry said the multiple blazes have put the state "way ahead of schedule" this fire season.
"Right now we're operating near full capacity," Curry said, adding that fire officials have called in reinforcements from across the West. "We haven't had the need for that level of fire management, expertise and capacity for several years."
