Live updates for Thursday: Firefighters work to get containment on wildfires burning across Coloradoโ€™s Front Range


Fire crews are spread across the Front Range as hot, dry weather is fueling three wildfires Wednesday in the foothills, forcing thousands of people from their homes.

One person has died in the fire near Lyons, according to the Boulder County sheriff.

The Alexander Mountain fire started Monday morning west of Loveland and by Wednesday morning was confirmed at 5,080 acres with numerous evacuations in Larimer County.

The Stone Canyon fire was reported Tuesday afternoon north of Lyons, and by Wednesday morning had burned 1,320 acres in Boulder County, with no significant growth overnight. It is burning just a few miles from the Alexander Mountain fire.

Late Tuesday night, the Quarry fire started in Jefferson County and had burned 130 acres by Wednesday morning.

Wednesday afternoon, the Boulder County Sheriff’s office announced a fourth fire that forced evacuations at the Lake Shore Park neighborhood near Gross Reservoir.

The cause of the fires has not been released but investigators at the Alexander Mountain fire are asking anyone with information regarding the cause and origin of the fire to call the Forest Service tip line at 303-275-5266. 

All those fighting the fires are concerned about the sweltering conditions. Near-record high temperatures are expected this week along with low humidity and high winds.

Boulder County Sheriff Curtis Johnson said Tuesday the weather is not going to change for several days and conditions are about as bad as they can be to fight fires. 

โ€œItโ€™s going to take us days to really manage it,โ€ he said of the Stone Canyon fire. โ€œThe fire has been jumping around a little bit.โ€ 

As well as resources that are stretched thin across the state and the Western U.S. as major fires burn in California, Oregon and Idaho.

Smoke from the Front Range fires is causing air quality problems along the Interstate 25 corridor and to the east.

Fire crews start to contain fire

Officials said Wednesday night they had 20% containment on the fire, which has slowed but continues to move to the northeast. Ground crews were working the fire lines overnight, and air support is expected to resume Thursday morning.

โ€” 7:35 p.m. Wednesday

Coordinated help with evacuations

The sheriffs of Larimer and Boulder counties have been sharing resources between their departments, including helping with getting people out of the way of the oncoming flames. 

Boulder County Sheriff Curtis Johnson said his team went up to Larimer County to help Monday morning when the Alexander Mountain fire started. When the Stone Canyon fire started Tuesday near Lyons, Larimer County deputies went to Boulder County to help with evacuation notices, he said.

There is one death related to the Stone Canyon fire, and Gov. Jared Polis said he has not heard of any issues with notifications to residents in evacuation areas.

โ€œI haven’t been made aware of any issues with the reverse 911,โ€ Polis said Wednesday at a new conference in Loveland. โ€œThe areas under mandatory evacuation have had an extensive door-to-door outreach of every household thatโ€™s in those areas.โ€ 

Officials at the news conference didnโ€™t specifically say if they made contact with the home where human remains were found, and said they werenโ€™t discussing the death while the investigation was ongoing.

โ€” 2:04 p.m. Wednesday

Bringing back firefighters, asking neighbors for help

Stan Hilkey, the executive director of the Colorado Department of Public Safety, said resources are being shared among the three fires burning on the Front Range. Two firefighting helicopters have also been brought in from Wyoming.

Hundreds of Colorado firefighters have been dispatched to help fight fires in California and other parts of the Western U.S., but Hilkey said he is asking fire chiefs around the state to bring back those firefighters to help here.

โ€œThe good news is weโ€™re not severely impacted at the moment. โ€ฆ I do get a little worried about our long haul and our ability to staff these fires in a long-term way,โ€ Hilkey said. โ€œI think my message is to the fire chiefs who have sent staff there, we support that noble mission of helping our partners because our partners help us when we need it. But I also think as opportunity arises, and with the weather patterns weโ€™re going to have for the rest of the summer, Iโ€™d feel a lot comfortable if we had a lot of those resources back in the state to help us with the long-term impacts.โ€

โ€” 1:24 p.m. Wednesday

Calling on National Guard

Gov. Jared Polis has called out the Colorado National Guard to help with logistics in fighting the fires on the Front Range. Soldiers wonโ€™t be on the front line fighting the fires but will be used to help with support, traffic management and other support roles.

Itโ€™s the first time since the Marshall fire in December 2021 that the National Guard has been used to help with fire support.

โ€” 1:14 p.m. Wednesday

Some evacuations being lifted

Residents in parts of northern and western Lyons have been given the all clear to return to their homes. Evacuations have been lifted in some areas, and residents can go to boco.org/infomap to check to confirm if they can return.

โ€” 11:50 a.m. Wednesday

At least one dead and five structures destroyed

One person has died, at least five structures have been destroyed and more than 1,300 acres have burned, with no significant growth overnight, officials said Wednesday morning.

โ€œShould things get hot and start burning again, we do have a lot of law enforcement resources staged here and also on standby,โ€ Boulder County Sheriff Curtis Johnson said. โ€œIf we do need to do additional evacuations, we can ramp up quickly and get people out of harmโ€™s way.โ€

Two structures destroyed

At least two structures have been destroyed and more than 1,300 acres have burned, with no significant growth overnight, officials said Wednesday morning.

When the Stone Canyon fire started about 1:30 p.m. Tuesday, air resources from the Alexander Mountain fire burning to the north in Larimer County were quickly diverted to help control the spread, Boulder County Sheriff Curtis Johnson said.
โ€œWe were fortunate to get air resources today because of the Alexander Mountain fire. Weโ€™re doing everything we can to get everybody we need here to fight this fire,โ€ said Johnson, who added he had been โ€œon pins and needlesโ€ since the Alexander Mountain fire started Monday.

Smoke creates problem for pilots

As the fire continues to move to the north and west, fire crews worked on the east side of the fire to protect the Sylvan Dale Guest Ranch, which is to the east of where the fire started Monday. The fire has not jump Highway 34 to the south.

Heavy smoke created visibility issues for aircraft, but they continued to drop slurry and water on and around the flames.

โ€” 9:45 p.m. Wednesday

More evacuation orders 

People in Glen Haven and to the west are on voluntary evacuation order as the fire moves closer to Estes Park. 

On Wednesday morning campers at Cheleyโ€™s Boysโ€™ Trailโ€™s End camp, near Glen Haven, packed their belongings and were relocated to the Land Oโ€™Peaks site just south of Estes Park. The girlsโ€™ camp, in the same area, was packed and ready to move if evacuation orders were issued.

โ€œTheyโ€™re in a pretty populated area, so weโ€™re just waiting to hear from authorities,โ€ said Jeff Cheley, the campโ€™s owner and operator. โ€œThe goal is to keep everything as normal as possible as long as we can.โ€ Over the course of the day about 60 campers were moved to the other site.

โ€” 5:01 p.m. Wednesday

Feds to help with firefighting costs

Federal funds will be available to cover the costs of fighting the Alexander Mountain and Stone Canyon fires in northern Colorado. 

The Federal Emergency Management Agency approved the stateโ€™s request for federal Fire Management Assistance Grant as the fires โ€œthreatened such destruction that it would constitute a major disaster.โ€

The funding will pay 75% of the stateโ€™s firefighting costs. The grants do not cover individual home or business owners and do not cover other infrastructure damage, FEMA said.

Old burn scars helping firefighters

Mike Smith, the incident commander for the Alexander Mountain fire, said Wednesday morning crews are focusing on the western and northwestern sides of the fire where it is most active. Firefighters are getting help from the burn scars from the Bobcat Gulch fire from 2000 and the Cameron Peak fire from 2020.

โ€œWeโ€™re really looking at the Bobcat and Cameron Peak fire scars. Those are going to really help us to keep that fire from marching too far forward,โ€ Smith said. โ€œIt did go into that Bobcat fire from 2000 yesterday and we saw a decrease in fire behavior. As it gets into the Cameron, itโ€™s even going to do more. So weโ€™ve got some good options up there.โ€

He said the rocky terrain in the Big Thompson Canyon is helping keep the fire from jumping over Highway 34, which connects Loveland to Estes Park, and they are closely monitoring that side of the fire.  The highway remains closed.

โ€œItโ€™s like a war zone out hereโ€

John Vierthaler, who lives in Deer Creek Canyon, said he could see flames approaching his home when the Quarry fire ignited Tuesday night.

โ€œWe saw a lot of flames,โ€ he said. โ€œIt was very, very disconcerting. There was a huge amount of smoke.โ€

Vierthaler hasnโ€™t evacuated from his home because itโ€™s too difficult to get his five horses and two donkeys ready to leave. Heโ€™s seen an armada of firefighting aircraft battling the fire throughout the day Wednesday.

โ€œItโ€™s like a war zone out here,โ€ he said.

Vierthaler said he and his wife have two pickup trucks ready to go should the fire get closer to their property. All of their critical documents and medications are packed, too.

The Quarry fire isnโ€™t the first time the couple has faced nearby flames. They evacuated during the Hayman fire in 2002, but the blaze ultimately never got close enough to be a real threat.

The Quarry fire burning in Jefferson County has consumed about 200 acres, but so far no structures have been lost. 

Mark Techmeyer, a spokesman for the Jefferson County Sheriffโ€™s Office, said firefighters are keeping flames out of neighborhoods, but that the fire is encroaching on homes.

โ€œEvery neighborhood in this facility is at risk,โ€ he said.

Techmeyer said there are helicopters and airplanes battling the blaze. 

The fire investigation hasnโ€™t really started, he said, but โ€œwe know right where it started.โ€ He said the ignition source is suspicious. 

Anytime you see a fire like that start at 9 p.m., โ€œit makes you scratch your head a little bit,โ€ he said.
