The National Park Service recorded audio of flames spreading at the heel, or the back side, of the Maple Fire August 8, 2016 in Yellowstone National Park. Recorded from about 15 feet away, the fire activity was not extremely intense, but at about 14 seconds, you’ll hear a small clump of lodgepole pine trees burst into flames, or “torch.” In listening to the 60-second audio file below, you might want to turn up the volume.
The Maple Fire burned over 40,000 acres northeast of West Yellowstone, Montana.
The historic Mount Holmes Fire Lookout burned in Yellowstone National Park Tuesday after being struck by lightning. It had not been regularly staffed since 2007. The fire was reported Tuesday by the employee who staffs the Mount Washburn Fire Lookout.
The lookout is in the northwest corner of the park southwest of Mammoth Hot Springs.
The structure fire also damaged a park radio repeater.
Wednesday morning, July 17, three employees including the park fire chief attempted to fly to the 10,000-foot lookout via helicopter to assess the damage. However, the flight was diverted to a higher priority incident outside the park. While en route, the helicopter manager snapped a photo of the burned lookout. Wednesday afternoon, staff attempted to fly to the lookout again but were grounded due to strong winds. Additional attempts will be made in the next few days.
“Built in 1931, and renovated in 1998, the Mount Holmes Fire Lookout maintained its historic-era role as one of Yellowstone National Park’s staffed lookout stations until 2007″,said Yellowstone National Park Deputy Superintendent Pat Kenney. “The building was eligible for inclusion on the National Register of Historic Places, both for its significance in early park resource protection efforts, and as an outstanding example of the rustic architectural style that typified early park architecture. We are disappointed that this historic structure, as a window into the past, is gone.”
The Mount Washburn Fire Lookout is currently staffed seven days a week, mid-June through mid-September. If warranted, three additional lookouts can be staffed.

In 28 interviews of experienced wildland firefighters of seven different agencies in Northern Colorado and Southern Wyoming researchers asked them about their observations of fire behavior in beetle-attacked lodgepole pine forests, with a focus on what they considered surprising from a fire behavior standpoint and how this in turn affected their suppression tactics. The interviews focused on 13 wildfires that occurred during the 2010 through 2012 fire seasons.
Below is an excerpt from a paper written by the researchers:
“The surprises in fire behavior experienced by firefighters during the red phase of post-outbreak forests included an elevated level of fire spread and intensity under moderate weather and fuel moisture conditions, increased spotting, and faster surface-to-crown fire transitions with limited or no ladder fuels.
“Unexpectedly, during the gray phase in mountain pine beetle-attacked stands, crown ignition and crown fire propagation was observed for short periods of time. Firefighters are now more likely to expect to see active fire behavior in nearly all fire weather and fuel moisture conditions, not just under critically dry and windy situations, and across all mountain pine beetle attack phases, not just the red phase. Firefighters changed their suppression tactics by adopting indirect methods due to the potential fire behavior and tree-fall hazards associated with mountain pine beetle-attacked lodgepole pine forests.”
In 2016 some areas in Yellowstone National Park that burned in the 1988 fires unexpectedly burned again, and with surprising intensity
By Kelly April Tyrrell, University of Wisconsin
In August 2016, areas of Yellowstone National Park that burned in 1988 burned again. Shortly after, in October 2016, ecologist Monica Turner and her team of graduate students visited the park to begin to assess the landscape.
“We saw these areas where everything was combusted and we hadn’t seen that previously,” says Turner, a professor of integrative biology at the University of Wisconsin–Madison who has closely studied Yellowstone’s response to fire since 1988. “That was surprising.”
In a study published this week [May 20, 2019] in the Proceedings of the National Academy of Sciences, Turner and her team describe what happens when Yellowstone — adapted to recurring fires every 100 to 300 years — instead burns twice in fewer than 30 years. Yellowstone as we know it faces an uncertain future, the researchers say, and one of the big questions they hope to answer is whether the forests can recover.
With Rapid Response Research funding from the National Science Foundation, Turner and her team returned to Yellowstone in the summer of 2017 to study the areas that re-burned. These include the Maple Fire, which burned 28-year-old lodgepole pines that regenerated following the 1988 North Fork Fire, and the Berry Fire, which contained 28-year-old lodgepole pines that had regenerated after the 1988 Huck Fire and 16-year-old trees that regenerated following the 2000 Glade Fire.
In each area, they compared to areas that burned in 1988 or 2000 but did not burn again in 2016.
The project would take place in the Medicine Bow National Forest in southern Wyoming
The U.S. Forest Service has a plan to treat 360,000 acres in the Medicine Bow National Forest in southern Wyoming by logging, thinning, prescribed burning, and building 600 miles of roads. The justification for what they are calling the Landscape Vegetation Analysis project, or LaVA, is to treat areas in the forest with the intention of “restoring forest health”. This area just north of the Colorado/ Wyoming border has been heavily impacted by Mountain Pine Beetles, so it fits the agency’s definition of an unhealthy forest and is considered by the U.S. Forest Service as an undesirable condition.
The Forest Service intends to build 600 miles of roads, clear cut 95,000 acres, selectively cut or commercially thin 165,000 acres, and use prescribed fire, mastication, and hand thinning on 100,000 acres.
Climate change that brought drought and warmer weather has provided a better habitat for the beetles. During normal times their spread is inhibited in the higher elevations by cold winters. Several days with low temperatures of around 35 degrees below zero can knock them back, but if that does not occur the rice-sized insects can come back with a vengeance the next summer.
Beetle-killed trees can be hazardous to firefighters due to the possibility of falling trees and burning snags. And, 5 to 15 years after the outbreak heavy ground fuels make fireline construction difficult. The dead trees can also be problematic near roads, trails, and structures. But a couple of years after the beetle attack and the red needles have been shed, the tree skeletons are less prone to crown fires than green trees. In 2015 University of Colorado Boulder researcher Sarah Hart determined Western U.S. forests killed by the mountain pine beetle epidemic are no more at risk to burn than healthy Western forests. Other scientists have found similar results.
Not everyone considers the plan a good idea. Some biologists say science doesn’t back up the efficacy of the treatments proposed, particularly logging and the prescribed burns that the Forest Service calls necessary for lodgepole pine to reproduce and more diverse species to take root.
“They say they are going to reduce fuel loads to limit wildfires, and the literature doesn’t support that,” said Daniel B. Tinker, an associate professor at the University of Wyoming, who has studied the region for 23 years. “We’ve had fires this summer that burned through areas that were clear-cut 15 years ago. Those stands weren’t supposed to burn for 100 years.”
Conservation groups also say the Forest Service truncated scientific review in a rush to meet congressional demands for increased timber production on public lands. For now, the proposal does not specify which parcels would be targeted and where those hundreds of miles of road would be built.
In the Washington Post, article Andy Stahl, executive director of Forest Service Employees for Environmental Ethics, was quoted as saying “Certainly, prescribed burning doesn’t pay its way — it’s expensive at around $100,000 per acre.”
If there is a prescribed fire somewhere that actually cost $100,000 an acre, which is very hard to believe, it is definitely an outlier. The costs vary greatly across the country and by vegetation type. They can be as inexpensive as less than a dollar an acre in Oklahoma, but usually run $10 to $250 an acre.
The federal agencies have had to cut back on their prescribed burning programs in recent years due to budget reductions.
The Forest Service expects to make a decision on the Medicine Bow plan in mid-2019.

We often hear about an area “recovering” from a wildfire. This implies that fire is unfortunate and unwelcome, a sentiment probably based on an instinctive fear. And it should go without saying — fires that burn structures or humans fit that description.
But vegetation fires in remote areas should be evaluated with different criteria. Yes, a fire can drastically change the appearance of a landscape. Most people visiting national parks, for example, would prefer to take pictures of a mature green forest than a recently burned hillside that is beginning a new fire return cycle. But those two ends of the cycle and everything in between are natural.
In 1988 fires in Yellowstone National Park caused mostly by lightning burned 793,880 acres, 36 percent of the park, during windy weather following a dry spring and summer. Today I saw an article that was focused on to what degree the vegetation had “recovered” from those fires 30 years ago. The emphasis was how much the landscape looked like it did before the fires of 1988. One might say that a lodgepole forest that burned at the end of its 50 to 300 year fire return interval had recovered the day after the embers cooled.
The photo below taken in 2003 in Yellowstone National Park in an area that burned in 1988 shows the regrowth of the forest in just 15 years.
Below are satellite photos provided by the US Geological Survey of the Yellowstone area taken a year before, just after, and 30 years after the 1988 fires. The red areas are not the actual color of the vegetation, but represent the areas where the fires burned, as detected by shortwave infrared, near-infrared, and visible green sensors on a satellite. As the vegetation changes, light green areas start replacing the red and pink from the burn scar.
