Homeowners drive along Deer Meadow Way under the watch of Colorado National Guard members as they are evacuated from a subdivision east of Red Feather Lakes, Colo., on Sunday, June 17, 2012, as the High Park Fire continues to burn in northern Colorado. Strong winds are fanning the blaze that has destroyed at least 181 homes, the most in the state's history.

LOVELAND, Colo. — Firefighters faced dangerous conditions across much of the Rocky Mountain region Monday, as hot, dry weather and expected gusty winds threatened to fuel a wildfire that has charred nearly 91 square miles in northern Colorado.

Authorities said three more homes may have burned in the fire near Fort Collins. The blaze started June 9 and already has destroyed at least 181 homes — the most in the state's history.

Crews continue to cut and dig lines around the flames, but containment has stayed at 45 percent since Saturday.

Temperatures in the 90s and wind gusts of up to 50 mph were expected Monday, a day after strong winds helped spread the fire and prompted more evacuation orders.

Other wildfires were burning in warm, arid weather from Wyoming to Arizona to Southern California, where a blaze that prompted the evacuation of at least 150 homes was 30 percent contained Monday.

Fire officials warned that the 907-acre fire in eastern San Diego County still threatens 200 houses, sheds and other buildings. The fire has destroyed at least one home.

In Colorado, another fire that started Sunday in the foothills west of Colorado Springs prompted evacuations of cabins, a Boy Scout camp and a recreation area near the Elevenmile Canyon Reservoir, which provides water to the Denver area.

That fire has burned about 1½ square miles, and fire managers said it has the potential to grow much more in the dry, windy conditions. Authorities hadn't listed a containment figure by Monday.

Meanwhile, a fire near Pagosa Springs in the southwestern part of the state grew to nearly 19 square miles and was 30 percent contained.

As firefighters try to get the upper hand on the blaze near Fort Collins, 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 Michael Stillman Maher, 30, 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 said they found a gun and stolen property in the vehicle.

Jeff Corum, whose home burned on the first day of the northern Colorado fire, described whirling, unpredictable winds that drove the blaze.

"That's what it's been doing, back and forth," Corum said. "It's just like a washing machine, and it's just rolling up there, and that's the way the mountains are."

Corum grabbed some clothing and two weapons when he fled, but not his credit cards. He's spent a few nights in a motel, some at a Red Cross evacuation center and some in his truck.

He's keeping a list of people and agencies who have handed him cash, paid for his laundry and given him tools to sift through the remains of his home when he's allowed back in.

The fire also is forcing wildlife to flee the flames. A moose seeking shelter in Fort Collins is back in the wild after swimming across Horsetooth Reservoir, the Fort Collins Coloradoan reported (http://noconow.co/M0G9M3 ).

Wildlife officials tranquilized the moose, blindfolded it and moved it to an area away from the fire. City officials say they're expecting more wild animals than usual because of the fire.

On Monday, Rocky Mountain National Park enacted a ban on all campfires because of the threat of wildfires in Colorado. The park normally allows campfires in designated fire rings, but the ban will prohibit those, as well as charcoal grilling, for the first time since September 2010.

Authorities also are trying to enforce a ban on using private fireworks in Colorado.

Across the West:

— California: Nearly 500 personnel have been dispatched to fight the fire east of Campo, in San Diego County. Water-dropping helicopters doused the area Monday, and firefighters braced for temperatures to rise and winds to pick up speed. Still, fire officials expected the blaze to be fully contained Tuesday night.

— Wyoming: A grass fire destroyed four homes in a small community outside Casper, Wyo., Sunday afternoon, but no one was injured. Another wildfire discovered Sunday has burned about 800 acres in the Medicine Bow National Forest.

— Nevada: Crews are fighting a 22,000-acre fire north of Ely, Nev., that has burned a mobile home. The person living there was evacuated, and no injuries have been reported in the fire burning steep, rugged terrain on the east side of the Schell Mountain Range, authorities said.

Also, Washoe County parks officials have banned campfires and barbeques at Galena Creek Regional Park just outside Reno, Nev. They cited dangerous fire conditions in forests all along the eastern slope of the Sierra.

— New Mexico: Firefighters are taking advantage of favorable weather conditions to battle a wildfire that has destroyed 242 homes and businesses. More than 1,100 firefighters remained in Ruidoso as they fight to hold the Little Bear Fire that is now 60 percent contained. Another fire in the Gila Wilderness, already the largest in state history, grew another 1,000 acres to 463 square miles. It's 80 percent contained.

— Arizona: Firefighters are focusing on protecting electrical transmission lines near a 3,100-acre blaze on the Tonto National Forest in northern Arizona. Officials said 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.

— Utah: A 208-acre blaze on the west side of Lake Mountain was fully contained Monday morning, officials said. The fire started Saturday and was human-caused. No structures are threatened.

— Nebraska: Firefighters are attacking the east side of a wildfire reported Sunday that has blackened roughly 1,500 to 2,000 acres in northwest Nebraska. No injuries have been reported, and there have been no reports of buildings being burned, authorities said Monday.
