The most recent updates from Tuesday were added to the top of the below section.
Wednesday's focus will be on U.S. 34 corridor, fire's northwest perimeter
Firefighters plan to focus efforts on the northwest perimeter and the U.S. Highway 34 corridor Wednesday, according to a news release from the National Forest Service.
Hotshot crews and multiple other resources will be arriving Wednesday to assist with firefighting operations. A Complex Incident Management Team will assume control of the fire Thursday, according to the news release.
As fire activity increased throughout the day Tuesday, multiple air resources dropped water and fire retardant to help secure the fire's perimeter, according to the news release. More than 270 firefighters were on the ground focusing on preserving critical infrastructure and private property.
Dry fuels, high temperatures and low humidity made firefighting difficult Tuesday, and those conditions are expected to continue through the week, with a slight chance of rain over the weekend.
The cause of the fire is still under investigation. Anyone with information about the cause or origin of the fire is asked to call the forest service law enforcement tip line at 303-275-5266. People can also submit photos and videos to on the forest service's website.

Incident commander for Alexander Mountain Fire: 'We're doing what we can when we can'
The Alexander Mountain Fire is changing so rapidly that there wasn’t even a map at the Tuesday afternoon news conference at Sylvan Dale Ranch, said incident commander Mike Smith.
The fire that was 900 acres on Monday night is, less than 24 hours later, burning 3,500 acres with zero containment, he said.
“Seeing that sort of fire growth overnight speaks to the dryness of the fuels and the dryness of the atmosphere. Those things combined with wind really lead us to the situation that we see here,” Smith said.
The fire is “impinging” on residential structures, Sheriff John Feyen said, but it’s unknown whether those structures have actually caught on fire.
“We just know that the fire has backed into those areas,” he said.
Fire activity is preventing crews from getting in to see what is going on at those structures, but Feyen said they will soon as it’s safe to do so.
Smith said firefighter and public safety is the top priority.
“If we can’t get in and engage this fire safely and make sure our folks can get in and get out and do the job they need to, we’re not going to commit those resources,” Smith said. “So, we’re doing what we can when we can.”
Jason Sieg, acting forest supervisor for the Arapahoe and Roosevelt National Forest, said the cause of the fire is still under investigation.
The fire is seeing growth on three sides, west, north and east.
Smith said crews are having success fighting it on the east side, but they’ve also had a recent shift in the wind, coming from the north, that they are now contending with.
More resources are coming Wednesday.
A complex incident command is taking over Wednesday and will have more resources than the Type 3 incident command, Smith said.
Hotshot crews and Type 2 crews are headed to the fire, Smith said.
The specialized teams can handle challenging terrain and technical assignments.
“They are in real short supply and the fact that we’ve got two coming is helpful, but boy we’d take all we could get.”
At any moment now, he said, the operation expects to receive what is known as a scooper, a fixed-wing aircraft that skitters on the surface of nearby lakes or reservoirs to get water to drop on the fire, allowing for a shorter turnaround time.
Smith said there is a shortage of resources for fires nationally, but this fire has been receiving good support due to the potential impacts that it poses to the community.
The weather is expected to be hot, dry and windy until Friday, when there will be a chance for moisture, but not anything significant, Smith said.
Mandatory evacuation notices have been sent to 3,245 devices, and voluntary notices were sent to 824 devices, Feyen said.
He said the sheriff’s office has been inundated with people offering help, and while he expressed gratitude, he asked that people not drop off supplies, saying the sheriff’s office is well resourced. Instead, he asked people to reach out to the American Red Cross to see how they can help.
The fact that there have been no injuries to either firefighters or the public is a huge bright spot, Smith said.

Mail deliveries continue as residents evacuate
As sheriff’s deputies were knocking on doors and driving down Larimer County Roads 27 and 29, and through neighborhoods between the two knocking on doors and broadcasting the mandatory evacuation order over loudspeakers, mail and packages were being delivered to those same homes by the U.S. Postal Service and FedEx.
Many residents were slowly packing important items into vehicles preparing to leave, but there was not the sense of urgency one might expect. Others flat out refused to leave.
Theresa Farrar said she and her husband and adult son had been packing up vehicles preparing for possible evacuation all morning. They were still loading items into a recreational vehicle, a fifth-wheel camper trailer, and three vehicles, including one towing a trailer with an ATV, from their home just east of LCR 27 at 2:15 p.m., as a sheriff’s deputy was going door to door to make sure everyone knew they were in an evacuation zone.
“We’re ready to go now,” she told a Coloradoan reporter just before they pulled out of the driveway of the home they’ve lived in for the past 17 years.

Larimer County declares formal disaster emergency
Larimer County Board of Commissioners Chair John Kefalas declared a disaster emergency in order to access local, state and federal resources for the Alexander Mountain Fire firefighting efforts.
"By declaring a disaster, Larimer County can activate our local Emergency Operations Plan to respond proactively to this ongoing event," Director of the Larimer County Office of Emergency Management Lori Hodges said in a news release. "It also allows us to access local disaster policies as well as state and federal resources as needed during this event."
Multiple statewide agencies are also supporting the response to the Alexander Mountain Fire by providing three air tankers, a Firehawk helicopter, a multi-mission aircraft, firefighter crews, intelligence and management support, communications support and assistance with road closures, according to a news release from Governor Jared Polis's office.
The state division of fire protection and control, department of homeland security and emergency management, state patrol, department of transportation, department of human services, department of agriculture, department of public health and environment and Colorado State University are coordinating to respond to the Alexander Mountain Fire, according to the state news release.
The state is also coordinating resources to respond to two other fires: the Ed Joe Draw Fire in San Miguel County and the Currant Creek Fire in Delta County.
“The State is rapidly responding to fires across multiple counties with a coordinated, multi-agency approach," Polis said in the news release. "I thank all the brave first responders and local, state and federal agencies who are currently working to protect Colorado communities and lands. Fire safety is a state-wide effort and I encourage Coloradans to practice fire safety at all times. We will continue working to help protect Coloradans, our communities, and prevent costly damage."

Longtime resident in evacuation zone: 'We ain't leaving'
Roy Logan was watering down the steel roof of his home at the intersection of Larimer County Road 27 and Arkins Drive to wet any dry leaves or grasses that might have collected in his rain gutters as sheriff’s deputies were going door to door to make sure residents knew they were in a mandatory evacuation area.
He wasn’t about to leave the home he’s lived in for more than 40 years, though.
“We ain’t leaving,” he told a reporter. “I didn’t leave for the Bobcat (Ridge Fire) and I’m not leaving now. I’ve been here since 1983 and been through a couple of these, and we haven’t left for any one of them. Just doing some preventative work; that’s the key.”

Evacuee: 'Wildfires are nothing to play with'
Robert Vincent and his family were packing up their vehicles and loading up horses, chickens and cats while evacuating their home along Larimer County Road 27 between Masonville and U.S. Highway 34 just before 1 p.m., about an hour after receiving a mandatory evacuation notice.
They were packing items into the back of a Subaru station wagon, an SUV and a pickup truck with a camper shell and preparing to get their animals loaded in crates and trailers.
“Wildfires are nothing to play with,” Vincent said, “especially after seeing how much bigger this fire got overnight and in the last couple of hours.”
Just across the road, Chad Kline and his wife were packing up some important items from their home. They were out of town when they received notice that their home was now in a mandatory evacuation zone.
“We were up in the mountains for the weekend, so we came down the canyon and are just trying to grab some of our belongings,” Kline said. “I see how great the firefighters and first responders and the sheriff and police are doing, so I’m just trying to get out of their way, because I know they need County Road 27 to do their job.
“I appreciate the hard work they’re doing, and I’m thankful they let us in. … We were here four years ago, and they did a great job with the Bobcat (Ridge Fire), so I have the utmost respect. I just want to get in and get out of their way.”
About 20 minutes after they arrived, they drove away again.

Evacuees moving large animals to Greeley
Evacuees who brought their horses and other large animals to the animal evacuation site at The Ranch events complex in Loveland will have to relocate to Island Grove Event Center in Greeley.
One hundred animals have been brought to the northwest edge of the Larimer County Fairgrounds complex, Capt. Bobby Moll with the Larimer County Sheriff’s Office said: 65 horses, five donkeys, 10 head of cattle, seven alpacas and 13 goats.
But the sheriff’s office was getting ready to move those animals to Greeley on Tuesday afternoon, in part, because the Larimer County Fair & Rodeo set to begin on Friday, Moll said.
It’s unclear how long evacuations will be in place, but he said if they last more than a few days, Island Grove will be a quieter setting with fewer crowds and more room for the animals and their owners, even though it has the disadvantage of being farther away.
On Tuesday, less than a dozen evacuees were on site with their animals.
One evacuee expressed frustration about the move but said the first priority was getting their animals settled in their new location.
Moll thanked the sheriffs posse for their efforts to evacuate animals, calling them “truly remarkable.” he thanked The Ranch staff members, who set up the metal pens that were holding the animals under a hot, hazy sky Tuesday afternoon.
A few trailers arrived just before 1 p.m. Tuesday to load the animals for transport.

Large animal evacuations moving to Island Grove
Starting at 2 p.m. Tuesday, all large animal evacuations will move from The Ranch Events Complex in Loveland to Greeley's Island Grove Regional Park, the Larimer County Sheriff's Office announced on Facebook late Tuesday morning.
Evacuated animals smaller than a goat can still be taken to NOCO Humane, where 51 animals — a mix of dogs, cats, chicken and one guinea pig — were being temporarily cared for as of 12:20 p.m., according to NOCO Humane.

Sheriff: No injuries, no structures burned
Firefighting efforts continued to focus on protecting people and structures Tuesday, Larimer County Sheriff John Feyen told reporters in a morning news briefing at Big Thompson Elementary School, where the roadblock closing U.S. Highway 34 to westbound traffic has been established.
The Alexander Mountain Fire was at 1,820 acres based on the most-recent mapping available, Feyen said, and had grown mostly to the north and northwest overnight.
That put the fire perimeter within about three-quarters of a mile of burn scars from both the Cameron Peak and Bobcat Ridge fires, where officials hope the lack of fuel will stop the spread, he said.
No injuries had been reported, and no structures had been burned, Feyen said during the briefing at 10:30 a.m.
The changeover in fire management kept the helicopters and airplanes that were working the fire Monday grounded for a few hours Tuesday morning, until they could be re-authorized and re-assigned through the new command team, Feyen said. A single-engine tanker began retardant while Feyen was speaking, and a helicopter began dumping water on the fire’s eastern edge about 11 a.m.
Fire engines and crews from across the state were being dispersed to protect the nearest homes and other infrastructure in the area, Feyen said. The closest homes to the fire are located more than a mile west of the fire’s eastern perimeter at Sylvan Dale Guest Ranch, which is being used as a staging area for firefighters and other emergency responders. Fire engines and crews from Arapahoe County and Brush were waiting in Masonville a little after 11 a.m. to see where they would be deployed, a firefighter said.
Although fire management was turned over to a U.S. Forest Service Incident Command team Tuesday morning, the Larimer County Sheriff’s Office is still responsible for evacuations and emergency response, he said. Geographical “trigger points” established during the Cameron Peak Fire in 2020 will determine any additional evacuations, with the biggest concern being homes along Larimer County roads 27 and 29 between Masonville and U.S. Highway 34 and those south of Highway 34 if the fire were to cross the road, he added.
“We drew our box very large yesterday, and we did that for a couple of reasons. The reason we did that is because is we want people to have plenty of time to get wedding albums, their big animals, all those kinds of things out of their homes that they want.
“And also, should the fire get bigger overnight and make a huge run towards homes that we’re not trying to go door to door, because that’s one of our evacuation plans is we go door to door and make sure we make contact with everybody that’s in the home. We don’t want to do that at night, especially in the mountains. And we don’t want them to have to drive down, maybe pulling a trailer full of horses or llamas or whatever in the middle of the night," Feyen said.

Record precipitation in 2023 helping fuel Alexander Mountain Fire
The hot, dry weather this spring and summer, combined with last year's near-record to record precipitation, helped fuel the Alexander Mountain Fire, according to Becky Bolinger, assistant state climatologist.
Bolinger on X pointed out last year’s abundant moisture promoted vegetation growth that has now dried and become kindling.
“This could exhibit extreme (fire) behavior and be very difficult to manage,’’ she wrote. “Our saving grace is that we don’t have winds in the forecast. But I don’t think this fire is going away soon.’’
Mapping of the fire and surrounding area show very dry conditions over the past 90 days and an extremely high burn index, according to Climate Center mapping.

Fire presents challenges on north, west sides
Challenges remain on the north and west sides of the Alexander Mountain Fire as crews work to control the blaze that started west of Loveland Monday morning.
The fire, which nearly doubled to an estimated 1,820 acres Tuesday morning with the help of hot and dry conditions, is holding in the Cedar Creek area on its west side, though it's not expected to hold much longer, incident commander Mike Smith said during a briefing late Tuesday morning.
It has also worked its way down one-third of the Big Thompson canyon off of U.S. Highway 34, though it is expected to run out of fuel there, Smith said.
The fire remains about half a mile from Sylvan Dale Ranch and is slowly backing up and moving north, where challenges remain for the crews working to attack the blaze, Smith said. Roughly 220 ground resources and additional aviation resources are currently part of the firefighting efforts, he added.

Evacuees flee to overnight shelter
The American Red Cross shelter at Foundations Church in Loveland has served around 60 evacuees since it opened at 5 p.m. Monday.
About 30 people stayed on cots overnight inside the church, with 20 more parked in campers or trailers in the church parking lot, said Gary Zawilinski, a Red Cross volunteer serving as shelter supervisor on Tuesday morning.
An employee at an RV park in the Big Thompson Canyon, who declined to identify herself to the Coloradoan, said she got the news Monday that she wouldn’t be able to report to work due to the fire and evacuations.
She lives in Loveland but now she doesn’t know when she’ll be able to resume working. And she’s worried for those who live in the RV park year-round, whom she’s gotten to know in her three months working at the park.
She said there’s a lot of anxiety about not knowing how long the evacuation will last. She said she is worried about the fire being at zero containment and not knowing where it’s headed next.
With the smell of smoke in the air and ash falling in the parking lot, volunteers filtered in and out.
A snack station with coffee and water was set up in the lobby. A sign in the lobby of the church directed people to a cat and dog shelter in the building, but a church volunteer said they preferred people take their animals to NOCO Humane, which had taken in 49 animals as of 10:30 a.m. Tuesday.
Some residents showed up simply to offer their help. One man came to the front door, announcing that he had a water donation delivery.
Moments before, a woman approached Red Cross volunteers to offer her help for anything they or the evacuees might need.
Foundations Church is a go-to location for the Red Cross when they need shelter space, said Care Pastor Frank Cirone, who was coordinating the effort with the Red Cross. He said the church opens its doors to the Red Cross because it wants to be a place where people can find help to meet their needs and also hope.
Cirone said he and his wife lived along Pole Hill Road near Estes Park for years and they understand what it’s like to be evacuated.
He said the church has about 50 volunteers working and they have been told their church could be needed to shelter evacuees for up to a week.

Resources limited as other fires burn across the country and Canada
The Larimer County Sheriff's Office was focused on getting people out of the path of the Alexander Mountain Fire Monday afternoon, Larimer County Sheriff’s Office Emergency Services Coordinator Justin Whitesell said during a briefing.
More firefighting resources — including fire engines from across Colorado — were expected to join the Alexander Mountain Fire efforts in the next couple of days, Whitesell said Monday.
Firefighting resources were limited Monday owing to several other wildfires burning in California, Oregon, Utah and parts of Canada, Whitesell said.
"We are doing the best we can with the resources we have," he said, adding that fire engines in the area Monday were focused on evacuating people safely and protecting homes and structures.
