DENVER — Authorities ordered more evacuations as fire crews struggled against powerful winds fueling a wildfire that has charred more than 87 square miles of forested mountains in northern Colorado.
The firefighting force has steadily increased and by Sunday night officials said about 1,750 personnel were working on the fire, which was sparked by lightning and was 45 percent contained.
The High Park Fire burning 15 miles west of Fort Collins has destroyed at least 181 homes. The figure represents the most in state history, surpassing the Fourmile Canyon wildfire that destroyed 169 homes near Boulder two years ago.
Julie Berney with the Larimer County Sheriff’s Office said firefighters dealt with winds of 30 mph with gusts of up to 50 mph Sunday. Some rain moved through Saturday evening, but it wasn’t enough to quell the fire.
“The problem is that when you have a fire like this, even if it rains it evaporates before it hits the ground,” Berney said.
Despite the winds, fire officials said crews Sunday were able to maintain most existing fire lines, with the fire chewing through about 1,000 more acres.
Incident commander Bill Hahnenberg said he was pleased with the firefighters’ progress.
“A scenario could be we’ll lose some line, and then we just go after it the next day and the next day,” he said.
On Sunday afternoon, high winds prompted fire managers to ground all helicopters working on the blaze and to send 96 notices to residents, ordering the immediate evacuation of the Hewlett Gulch Subdivision in the Poudre Canyon area north of the fire. It was unclear how many homes were affected.
Sunday night, Larimer County officials said evacuations orders were also issued for Soldier Canyon and Mill Canyon areas. The officials said 331 notifications were sent.
A high wind warning was in effect all day, and crews are expecting more of the same Monday: winds of 30-50 mph, low humidity and high temperatures.
As firefighters try to get the upper hand on the blaze, which has burned large swaths of private and U.S. Forest Service land, local authorities have dispatched roving patrols to combat looting.
On Sunday, deputies arrested 30-year-old Michael Stillman Maher, of Denver, on charges including theft and impersonating a firefighter. The sheriff’s department said Maher was driving through the fire zone with phony firefighter credentials and a stolen government license plate.
His truck was later seen near a bar in Laporte, and investigators say they found a firearm and stolen property in the vehicle.
“There’s a handful out there that are taking advantage of others,” said Sheriff Justin Smith, adding that “if somebody’s sneaking around back there, we’re going to find them.”
Also Sunday, a fire erupted in the foothills west of Colorado Springs, prompting the evacuation of some cabins and a recreation area near the Elevenmile Canyon Reservoir. U.S. Forest Service spokesman Ralph Bellah told the Gazette (http://bit.ly/MiQvne) that the fire was reported at about 12:30 p.m. and quickly grew to up to 100 acres.
Meanwhile, a fire near Pagosa Springs in the southwestern part of the state has grown to 11,617 acres and is 30 percent contained. Hot, dry conditions Sunday are expected to fuel the fire, which was sparked by lightning May 13.
Across the West:
• California: Authorities are evacuating homes in eastern San Diego County as firefighters battle a 100-acre wildfire that has destroyed one structure. The California Department of Forestry and Fire Protection says the fire began Sunday afternoon in a rural area northeast of Campo and near the Golden Acorn Casino.
• New Mexico: A wildfire in southern New Mexico has destroyed 242 homes and businesses, and firefighters are working to increase containment and keep an eye out for possible lightning.
The 59-square-mile Little Bear Fire in Ruidoso is 60 percent contained. Dan Bastion, a spokesman for crews fighting the fire, says most of the fire is in the mop-up stage, but crews need to build more containment on the fire’s active west side to deprive it of fuel.
• Arizona: Firefighters are focusing on protecting electrical transmission lines near a 3,100-acre blaze on the Tonto National Forest in northern Arizona. Officials say hot weather and steep slopes remain a concern, and firefighters are on the alert for thunderstorms and possible lightning strikes. The fire is 15 percent contained.
