West Fork Complex fires: One year later

Staff Writer

On July 10, 2013 — one year ago today — southwest Colorado, namely the communities surrounding Wolf Creek Pass, were still reeling from the West Fork Complex fires, which totaled 109,100 acres as the day began.

At that point, the complex — made up of the West Fork, Papoose and Windy Pass fires — was 19 percent contained, and the West Fork Fire had been burning since June 5.

Luckily, however, the fire saw no more significant growth and monsoonal moisture soon lent a helping hand to fire personnel.

Chronology of a complex

Between June 5 and July 10, 2013, the fires grew, forcing the closure of national forest land and U.S. 160 over Wolf Creek Pass, evacuations, heavy smoke and more. Following is a brief chronology of the major events over that span of time. All acreages listed are for the morning of each day.

• June 5: The West Fork Fire begins west of the Continental Divide near Born’s Lake northeast of Pagosa Springs, in an area difficult to access. The cause is lightning and the size is estimated at one-quarter acre.

• June 13: A Type 3 incident commander arrives and additional resources are ordered. The Windy Pass Fire begins from a lightning strike 12 miles northeast of Pagosa Springs, near the Windy Pass Trail.

West Fork Fire: 25 acres. Windy Pass Fire: Unknown.

• June 14: Smoke begins to be visible from U.S. 160 and the West Fork Trail is closed. Additional resources are ordered. Thirteen backpackers are safely evacuated from the West Fork Trail and Rainbow Hot Springs.

West Fork: 150 acres. Windy Pass: unknown.

• June 15: An additional 20-person crew is ordered for the Windy Pass Fire. The fire grows to 35 acres by mid afternoon. More than 65 personnel are working each fire.

West Fork: 470 acres. Windy Pass: 5-6 acres.

• June 16: The two fires are now being managed as the West Fork Complex. A Type 2 National Incident Management Organization (NIMO) team is ordered. Falls Creek and Wolf Creek roads, Treasure Mountain Trail and Windy Pass Trail are closed.

West Fork: over 1,747 acres. Windy Pass: 108 acres.

A year later

Now, a year later, the blackened scars on the landscape remain, but the longterm effects of the complex fires are only beginning to show, and more effects will appear over time.

Last week, officials from several agencies toured a portion of the burn area from the West Fork Fire with the San Juan Headwaters Forest Health Partnership (SJFHP).

Among the officials on that tour was Steve Hartvigsen, forester of the San Juan National Forest. After the tour, Hartvigsen relayed some of the observations made about the fire area to The SUN.

The fire provides a unique opportunity, Hartvigsen noted, both because it burned a year after the Little Sand Fire (which occurred north of Pagosa Springs), allowing for comparisons, and because it essentially broke the mold — the beetle kill, due to the environment it burned in.

The fire was large-scale and burned primarily in spruce and fir, but was also in an area with a large population of beetle-kill trees, which provided a different type of fuel source than is traditionally seen.

Because of that beetle kill, Hartvigsen noted, the West Fork Fire burned much more intensely than the Little Sand Fire did the previous year.

During the Little Sand Fire, about 15 percent of the area burned at a moderate to high severity, compared with one-third of the area burned during the West Fork Fire.

Where the West Fork Fire was most intense, it consumed or killed most of the conifers and understory vegetation, Hartvigsen noted, while in areas of large aspen stands, the fire burned around the stand and reached in, but the inside of the stand appeared untouched.

It also remains to be seen how the understory will react, with early indications that aspen are sprouting not only from existing root systems, but also from seeds since the tree’s competition is gone.

A fire behaviorist on the tour also noted, Hartvigsen reported, that the fire moved from the crowns of trees down to the forest floor — the opposite of what is more often seen.

But, despite the intensity and size of the fire, Hartvigsen noted that the area burned by the fire is rather small when compared to the area of beetle kill in the area of Wolf Creek Pass — showing how great the spruce beetle outbreak is.

Hartvigsen also noted several observations about how the fire affected local wildlife, which were explained by a biologist on the tour. Hartvigsen said there is little indication of mortality among large ungulates that can move (such as deer and elk), though smaller mammals and birds were likely consumed by the fire.

Hartvigsen relayed that there also appear to be no indications of mortality among the lynx population in the area, with the local populations apparently adjusting and shifting out of areas where their prey base is declining.

For more information on the tour of the burn area, see related article in this issue of The SUN.

A landscape, changed

Though the effects of the fire are only beginning to show, it is clear that the landscape in the area of the burns will be different for a long time.

Hartvigsen noted that the intense fire, helped by the beetle kill, wiped out areas of spruce and, because spruce seed does not carry very far, there are now large areas with no seed source.

What that means is that there may now be more meadows across the landscape, with it taking several generations of trees to mature and spread seed back into those areas.

Therefore, Hartvigsen estimated, it could take 200 to 600 years for those areas to again be forested environment.

Accessing the burn area

Hartvigsen warned that anyone visiting the burn area should be cognizant of the surroundings, as the danger of falling trees greatly increases after fire — especially on windy days, when travel into the burn areas is discouraged.

Much of the burn area is easier to see and access from the west side of Wolf Creek Pass, such as from Big Meadow Road, which, from the Pagosa side, is just beyond the tunnel. On that road, the burn area is accessible by traveling beyond Shaw Lake and Lake Fork.
