Forest Service burned hundreds of acres of piles in the general area where the Calf Canyon Fire started

There is very little fire history out in front of the Calf Canyon – Hermits Peak Fire in Northern New Mexico

9:09 p.m. MDT May 13, 2022

About three months before the Calf Canyon Fire was reported April 19, 2022, employees of the Santa Fe National Forest ignited hundreds of acres of debris piles which were created during fuels treatment projects. The piles were “approximately 17 miles west of Las Vegas,” according to a notice posted at the New Mexico Fire Information website on January 26, 2022. (See below) The name of the project was Gallinas Canyon wildland-urban interface (WUI) prescribed pile burn. In January prior to the notice crews had already completed 266 acres of the 374-acre unit and planned to continue burning more piles “as early as January 27.”

Fires are usually named after a geographical feature near the point of origin. Calf Canyon Road intersects with Forest Road 263 which is in Gallinas Canyon.

On September 27, 2012 a 300-acre hazardous fuels reduction mechanical thinning project was finished just north of Calf Canyon Road, which likely left hundreds of piles to burn later.

This project and Calf Canyon Road are broadly within the general area where the Calf Canyon Fire started. There have also been other fuels treatment projects in that area over the last 10 years.

The US Forest Service has already identified an escaped prescribed fire as the cause of the Hermits Peak Fire, but lists the cause of the Calf Canyon Fire as under investigation.

Wildfires, prescribed fires, and pile burns are known to have smoldered for months, sometimes under snow and through an entire winter, before being discovered months later when smoke becomes visible. The burn piles were at approximately 8,000 feet, so the snow reported in the notice may have kept the vegetation cold and wet for a couple of months if the pile burning was completed in February. We are not saying that is what caused the Calf Canyon Fire, but investigators have no doubt evaluated that possibility and ruled it in or out.

Three days after the Calf Canyon Fire was reported strong winds and low humidities combined to caused it to merge with the Hermits Peak Fire and spread 10 miles to the northeast through dry vegetation in a 24-hour period.

What is next for the Calf Canyon / Hermits Peak Fire?

While the Calf Canyon / Hermits Peak Fire has been churning through more than 270,000 acres on its march to the north, at least 90 percent of those acres have burned in areas with no recorded history of previous fires in the national database, going back decades. If that spread to the north and north-northeast continues there is limited significant fire scars in the records out ahead that will slow the fire. (Update May 14, 2022: The NIFC database does not include two fires north of the Calf Canyon / Hermits Peak Fire; the 2020 Luna Fire (10,100 acres) and the 2018 Sardinas Canyon Fire (2,300 acres), according to the link provided in a comment by SE.)

The overall length of the fire is 45 miles as of Thursday night May 12. From the origins they ran north for 32 miles, and south for 13.

There are also no large completed fuel treatment projects in the national database north of the fire that could serve as barriers, except for several near US Highway 64 west of Angel Fire near Valle Escondido 14 miles away. But there are other fuels treatment projects at what is now the southeast corner of the fire in the Barillas Peak area. It has just started to burn into the 2,534-acre “Wildfire Commissary 2015” fire use fire, but it is possible that without too much trouble it could work its way around it, another smaller fire use incident, and a 600-acre prescribed fire conducted in 2004.

At the end of the day on May 12 the north end of the fire was 14 miles from US 64, 19 miles from Taos, 11 miles from the Cooks Peak Fire, and 25 miles from the Philmont Scout Ranch.

Most of the growth of the Calf Canyon – Hermits Peak Fire Wednesday was on the north end where it spread for one to three miles further north and northeast. As of Wednesday night at 10:39 it remained west of Highway 434. It increased by about 22,000 acres Wednesday to bring the total up to 259,810 acres.

Calf Canyon / Hermits Peak Fire

The Calf Canyon / Hermits Peak Fire made large runs on the north side Tuesday. The area that spotted over Highway 518 a couple of days ago east of Holman spread six miles farther north. Another slopover occurred Tuesday northwest of Holman and ran four miles to the north. When the fire was mapped at 11 p.m. Tuesday the fire had not spread east of the 434 road.

On the south end east of Barillas peak, an area that has been very active recently, it moved another two miles to the south.

Tuesday afternoon I briefly checked an aircraft tracking website and quite a few aircraft working the fire, thanks to a decrease in wind speeds and turbulence. At that time there were two large air tankers (MD-87s), one very large air tanker (DC-10), four scooping air tankers, at least two helicopters, as well as a lead plane and an air attack.

The blaze has now burned 236,939 acres, an increase of about 33,000 acres in 24 hours, and is now 13 miles southwest of the Cooks Peak Fire.

Cerro Pelado Fire

The map produced by an aircraft Tuesday night found incremental differences in the fire perimeter, but no large additional runs. Most of the changes were due to firefighters conducting tactical burning operations to tie in the fire’s edge to roads or other firelines.

The fire has burned 42,491 acres.

The Calf Canyon / Hermits Peak Fire near Los Vegas, NM grew substantially in two areas Monday and had burned a total of 203,920 acres by evening. On the north side, the spot fire east of Highway 581 that was 200 acres Sunday night spread east for more than 5 miles and burned about 8,000 acres by Monday night. When the fire was mapped at 10:24 p.m. Monday firefighters were holding it at the 434 road.

On the southwest side 9 miles west of Las Vegas near the A18A road the blaze spread for another mile and a half to the south. Operations Section Chief Todd Abel said Monday evening that the fire in that area was still within contingency firelines that have been constructed further south. Hand crews and engines are in the area improving lines and protecting structures.

On Monday there were scattered areas on the west side of the fire that were very active late in the afternoon.

The very strong wind prevented air tankers from working Monday, but Mr. Abel was gratified that a small Air Attack plane was able to find an altitude without too much turbulence and was able to reconnoiter and provide information to personnel on the ground. At one point we saw on an aircraft tracking site that the aircraft was orbiting at 20,000 feet, much higher than their usual operating altitude.

The Cerro Pelado Fire 7 miles southwest of Los Alamos was active Monday on the northeast and southeast sides. It was mapped Monday night at 42,491 acres, an increase of about 1,500 acres, and still had not crossed Highway 4.

The most significant spread of the Cerro Pelado Fire Sunday was on the northeast side south of Highway 4 where it spread for about a mile east and crossed the FR 289 road. When the fire was mapped at 10:24 p.m. Sunday a large spot fire had come very close to crossing the next road to the east, FR 287. The fire grew by more than 3,000 acres Sunday to bring the size up to 40,958 acres.

Most of the significant growth on the Calf Canyon / Hermits Peak Fire was on the north and south sides. When it was mapped at 10:50 p.m. on Sunday the north side, northwest of Cleveland, had advanced for about two miles further north coming close to Holman. There was a large 200-acre spot fire across Highway 518 east of Homan.

The east side of the Calf Canyon / Hermits Peak Fire still appears to be secure and the Sunday night map showed no change south of Mora and La Cueva near Highway 518. There was also no change near Las Vegas. But about 8 miles west of Las Vegas south of Highway 283 it spread south for an additional mile.

The fire grew by more than 13,000 acres Sunday to bring the size up to 189,767 acres.

Calf Canyon / Hermits Peak Fire

The Calf Canyon / Hermits Peak Fire near Las Vegas, New Mexico made it through Saturday’s wind event without any major devastating runs beyond the existing firelines, but it is not over yet. Red Flag Warnings are again in place Sunday for strong winds, low humidity, and very dry vegetation. The forecast for Sunday and Monday is for sustained 32 mph winds gusting out of the west-southwest at 40 to 48 mph with 8 percent relative humidity.

Operations Section Chief Todd Abel said Saturday evening that one of the most active areas on the fire was on the southwest side near Highway 283. He also said all aircraft working on the fire had to be shut down around noon Saturday when the winds became too turbulent.

The fire has burned 176,000 acres.

Cerro Pelado Fire

On Friday and Saturday most of the spread of the Cerro Pelado Fire was on the northeast side south of Highway 4, and on the southwest side. The 37,525-acre blaze is seven miles west-southwest of Los Alamos, New Mexico.

On the eastern side of the fire the FR 289 road is considered a primary line as the fire continued to advance in that direction pushed by 35 mph winds. A spot fire crossed the road late Saturday afternoon. Crews working that night shift described conditions in the area as “unbearable” due to wind, dust, smoke, and heat. Crews later engaged the spot fire at 3:00 a.m. Sunday when visibility had improved. Most of the movement to the east occurred in steep canyons. FR 289 has been prepped and plumbed with extensive hose lines.

Crews are coordinating with the National Park Service for structure protection in Bandelier National Monument and Valles Caldera National Preserve.

A Red Flag Warning is in effect for Sunday. The forecast for the fire area is for 39 mph winds gusting out of the west-southwest at up to 55 mph with relative humidity as low as 9 percent. On Monday the wind speeds will drop to 24 mph with gusts of 31 to 39 mph from the west-southwest.

Most of the blaze is in the footprint of the Las Conchas Fire that burned 156,593 acres in 2011. In a trial jurors found that two power companies were 95 percent responsible for starting that fire and the U.S. Forest Service was 5 percent responsible. The cause of the current Cerro Pelado Fire is listed as unknown.

Most of the growth of the Calf Canyon / Hermits Peak Fire on Wednesday and Thursday was in three areas, on the north side west of Mora, on the southwest side near Bear Mountain, and the southeast side west of Las Vegas. Most of the additional acres near Las Vegas were a result of large burning operations conducted by firefighters to secure the fire edge. A mapping flight Thursday night determined that the fire had burned 168,009 acres, an increase of about 8,000 acres over the previous two days.

An area that is of concern to many residents in the area, the portion of the fire near Las Vegas, is “looking awesome”, said Operations Section Chief Todd Abel in a Friday morning briefing, implying there was not much active fire and the control lines are in place and holding.

Mr. Able said the weather and fire conditions have allowed firefighters to build direct fireline on the north side just west of the community of Cleveland, which is good news with strong winds in the forecast (see below for more weather information).

The weather is going to be a challenge again this weekend due to what firefighters call a “wind event”.  According to the forecast Saturday will bring strong winds gusting to 39 mph, becoming even stronger on Sunday and Monday gusting to 45 mph. The direction will be generally out of the southwest and west while the minimum relative humidity each day hovers around 10 percent. These conditions will test the firelines on the east and northeast sides of the blaze. Firefighters, of course, are aware of the prediction and have been prepping structures, constructing and improving firelines, and building contingency lines further out.

Northern New Mexico weather

Over the last few days fire crews have been working north of the fire to be prepared if the fire makes a big run in that direction toward Chacon and Guadalupita South along the 519, 121, and 434 roads. Northeast and southeast of Mora they have used dozers to build firelines behind homes.

The Southwest Team #2 is bringing in a second team, a Type 2 team, Southwest Team #3. As explained by Operations Section Chief Todd Abel Friday morning, “They will integrate with our team. This means there’s still just one team, but we brought those people in to help us have a little bit more capacity so that if we have the potential to move further north that we have those folks available.”

Drought Monitor, May 3, 2022

Most of New Mexico is in extreme or exceptional drought.  The vegetation, or fuels, are atypically dry due to the drought, exacerbated by strong winds and high temperatures. Extremely dry fuels is one of the factors that can contribute to the rapid spread of a fire, especially when combined with very low humidity, high temperatures, and very strong winds.

The spread of the Calf Canyon / Hermits Peak Fire has been primarily through Ponderosa pine with a significant amount of dead and downed fuels in the understory. As the fire progresses downslope to the east, the dominant fuels transition through pinyon/juniper, Gambel oak, and brush to short grass.

Air tankers and helicopters assisting firefighters Tuesday provided an opportunity to engage aggressively on the ground. Structure protection, line construction and firing operations continued Wednesday.

The fire has grown to 160,104 acres and has destroyed 170 residences and 117 other structures.

To see all articles on Wildfire Today about the Calf Canyon and Hermits Peak Fires, including the most recent, click HERE.

Six Structure Protection Groups across the fire have been focusing on removing fuels, constructing line, and deploying other protection measures around homes and communities.

Crews continue to conduct firing operations to remove fuel between containment lines and the uncontrolled fire edge to control portions of fire. One of the largest is on the south end of the fire west of Las Vegas. It began near the Bradner Reservoir and worked south past Luna Community College down to Highway 283, a distance of 5.3 miles.

Firefighters are removing fuel along the north side of Highway 283 in case the fire comes down that far. This will also facilitate using the highway to anchor a firing operation if needed to keep the fire north of the highway.

On the north side of the fire a dozer line was constructed south of Cleveland and Mora from which crews burned out to help protect the communities.

A zoomable evacuation map is available online.

The weather forecast for Thursday indicates that the wind speeds will be lower than they have been for several days, 17 mph out of the west-northwest with relative humidity in the low teens. Friday will be similar, with slightly stronger winds from the west. The strong winds will return Saturday through Tuesday, out of the west and southwest. The speeds will be in the high 20s gusting close to 40 mph with single digit humidity.

Aviation resources include large and very large air tankers, 14 helicopters, and six water-scooping air tankers. The scooper planes are obtaining water at Lake Isabel which is on private property.

Other resources on the fire include 104 engines and 23 hand crews for a total of 1,208 personnel.
