Here are the highlights of the Thompson Fire evening update. No surprises, but some progress on the ground . . .

Fire Update: The Thompson Fire was reported at approximately 1:30 p.m. Sunday, Aug. 9. It is located in a remote south-central backcountry area of Glacier National Park about 15 miles east of the West Glacier entrance and 12 miles southwest of the Saint Mary entrance. The fire is burning in the Thompson Creek and Nyack Creek drainages west of Medicine Grizzly Peak where the Flathead and Glacier Counties border follows the Continental Divide. No structures have been lost or damaged to date and no injuries have been reported.

Crews worked in the Nyack Creek area today. A helitack crew worked on cooling any remaining hot spots around Upper Nyack Backcountry Patrol Cabin to provide additional structure protection. Other crews began constructing a wet line along avalanche chutes on the west side of the fire’s perimeter to contain the fire. This includes the use of helicopter water drops and pumps and hose lays on the ground. Fire personnel in the Two Medicine and Cut Bank drainages continued their structure assessment for possible protection if the fire were to cross the Continental Divide. They are also monitoring for any fire that might cross the Divide.

Although buffeted by winds on Friday, the fire remains west of the Divide and has not made any advance to the east. Without spread east of the Divide, the fire poses no threat to communities around East Glacier and St. Mary. Limited growth of the fire was seen on Saturday on the west side in Nyack Creek.

Weather will remain unsettled through Monday night with the passage of a weak disturbance. This provides an opportunity for afternoon thunderstorms and a slight chance of rain, especially along the Divide. A high pressure ridge will begin building on Tuesday through Thursday bringing warmer and drier conditions. This will bring increased fire spread on the ground with isolated tree torching. As fuels in the burn area dry, there will likely be an increase in smoke production that may be seen from local communities on both sides of the Divide.

Here are the highlights of this morning’s update on Glacier Park’s Thompson Fire. Short version: The fire is a little bigger (13,680 acres) and there are now people on the ground in the backcountry . . .

Approximate Size: 13,680 acres
Containment: 0% Latitude 48.551, Longitude -113.613

Fire Update: The Thompson Fire was reported at approximately 1:30 p.m. Sunday, Aug. 9. It is located in a remote south-central backcountry area of Glacier National Park about 15 miles east of the West Glacier entrance and 12 miles southwest of the Saint Mary entrance. The fire is burning in the Thompson Creek and Nyack Creek drainages west of Medicine Grizzly Peak where the Flathead and Glacier Counties border follows the Continental Divide. No structures have been lost or damaged to date and no injuries have been reported.

A crew was flown into the Nyack drainage area Saturday evening and established a spike camp to operate from. They will provide additional structure protection measures for the Upper Nyack Backcountry Patrol Cabin, including helicopter water drops if needed. They are constructing a wet line along avalanche chutes to contain fire from further spread. This includes the use of helicopter water drops and pumps and hose lays on the ground. A helitack crew is positioned at the helibase along US Highway 2 to provide support to Glacier NP fire managers in the event of any new fire starts. Fire personnel in the Two Medicine and Cut Bank drainages are assessing structures for possible protection if the fire crosses the Continental Divide. They are also monitoring for any fire slopover across the Divide.

Although buffeted by winds on Friday, the fire remains west of the Divide and has not made any advance to the east. Without spread east of the Divide, the fire poses no threat to communities around East Glacier and St. Mary. Limited growth of the fire was seen on the west side in Nyack Creek.

Sunday’s weather will remain cool with temperatures on the fire in the lower to mid-50s. Humidity will remain higher around 50%. Wind will be lighter at 12-16 mph from the southwest on ridges. Decreasing winds are predicted for the area by morning with a slight chance for showers. Temperatures will slowly increase and humidity decrease over the next several days, with a return to seasonal conditions. There is a slight chance for isolated thunderstorms and rain later in the day on Sunday.

Here are the essentials from this morning’s Thompson Fire update from the InciWeb site.

Short version: Cooler weather and last night’s rain should cause the fire to lay down a bit. They still intend to fly in a couple of ground crews . . .

If weather and smoke conditions permit today, two crews will fly into the backcountry area near the fire to work on control measures. One crew will land near Cutbank Pass to suppress hot spots along the fire’s edge and direct helicopter water drops. The other crew will work in the Nyack Drainage area to provide additional structure protection measures for the Upper Nyack Backcountry Patrol Cabin; cool down hot spots along the fire perimeter; direct helicopter water drops; and use pumps and hoses on any hot spots along the perimeter.

Gusty winds are predicted for the area through the morning with a chance for showers. Cooler weather and higher humidity are expected today, with a return to seasonal conditions Sunday. With cooler weather and recent rains, the fire is expected to smolder within its perimeter today. West Glacier received about 0.06 inches of rain in the past 24 hours: St. Mary received 0.19 inches…

From this evening’s incident update on the Thompson Fire we learn that the fire’s size estimate has been trimmed slightly to 13,202 acres and that they hope to start flying fire crews into the backcountry to fight the blaze on the ground . . .

A small fire was detected today on the west side of Waterton Lake on the U.S. side in Glacier National Park. Fire personnel are responding.

The Thompson Fire has not impacted any park roads. The Going-to-the-Sun Road is open.

The Thompson Fire grew to 14,900 acres (over 23 square miles) today and a Type II management team takes over tomorrow. Here’s the official news release . . .

The Thompson Fire expanded east yesterday and today into the higher elevations of the upper Nyack Creek area, located in the south-central region of Glacier National Park. The cause of the fire is under investigation.

The Thompson Fire is now estimated to be 14,900 acres. Dry vegetation coupled with high temperatures and low humidity resulted in extreme fire behavior and fire growth yesterday and today. The smoke plume has been visible from many locations on both sides of the Continental Divide.

A Type III Interagency Incident Command Team has been working with Glacier National Park to manage the fire using a contain and confine strategy. A Type II Incident Management Team has been ordered and will assume command of the fire tomorrow morning.

The safety of public and incident personnel is the highest priority on all incidents. At this time, ground resources cannot be safely used due to the remote, rugged terrain and the lack of safety zones in the area. The National Park Service’s Upper and Lower Nyack Backcountry Patrol Cabins remain threatened by the fire.

Yesterday’s fire activity has prompted expansion of the trail and campground closure order. For the most up-to-date information on the expanded trail and area closure statuses, visit http://home.nps.gov/applications/glac/infobull/closures.cfm.

As of Wednesday, August 12, campfires will not be allowed in the backcountry of Glacier National Park. Campfires will continue to be allowed only in designated sites in frontcountry campgrounds. Stage 1 fire restrictions remain in effect for Northwest Montana. For further information visit: http://www.nps.gov/glac/learn/news/fire-restrictions-for-back-country-of-park.htm.

The Reynolds Creek Fire continues to burn within the fire perimeter on the east side of the park. For information on fires within Glacier National Park, please visit http://inciweb.nwcg.gov/state/27/.

Woof! The Thompson Fire is now estimated at 11,400 acres, almost 18 square miles. A type II team has been called in.

The Missoulian has a good write-up. Also check out the map below to see the area covered by the blaze . . .

The Thompson fire in southeastern Glacier National Park exploded from 1,900 acres to about 11,400 acres between Monday and Tuesday afternoons, as western Montana recovered from a line of thunderstorms Monday night.

“The lack of moisture, high temperatures, low humidity and dry vegetation have resulted in extreme fire behavior and fire growth,” Glacier spokeswoman Katelyn Liming said in an email Tuesday. “The smoke plume is visible from areas on both the west and east sides of the Continental Divide.”

Given the fire’s remote location, the National Park Service is using a “contain and confine” strategy to manage it, Liming said. Helicopters are using bucket drops to cool its hot spots, while natural rock outcrops are blocking some of the spread.

The Thompson Fire is now five times as big as it was at the end of the day yesterday. Here is this afternoon’s official press release . . .

The Thompson Fire started on August 9th and continues burning in the remote Nyack area, located in the south-central region of the Glacier National Park. The cause of the fire is under investigation.

The lack of moisture, high temperatures, low humidity, and dry vegetation have resulted in extreme fire behavior and fire growth. The Thompson Fire is now estimated to be 5,500 acres this afternoon. The smoke plume is visible from areas on both the west and east sides of the Continental Divide.

A Type III Interagency Incident Command Team is working with Glacier National Park to respond to the fire. There are currently 35 fire personnel and two helicopters assigned, with additional air resources available. A Type II Incident Management Team has been ordered. The Team is using contain and confine strategy to manage the fire. This is being accomplished by using aerial resources with water bucket drops to cool hotspots. Fire managers are using natural (rocky) barriers to confine the fire. The National Park Service Upper and Lower Nyack Backcountry Patrol Cabins remain threatened by the fire. Containment actions are being taken to protect the lower cabin. These actions include fuel mitigation actions around the site and structure wrap of the cabin.

The safety of public and incident personnel is the highest priority on all incidents. At this time, ground resources cannot be safely used due to the remote, rugged terrain and the lack of safety zones in the area.

The Thompson Fire has prompted closure of the Nyack and Coal Creek areas, including trails and backcountry campsites. There will be additional trail closures in the area due to increased fire activity. For updated information on trail status, visit http://www.nps.gov/glac/planyourvisit/trailstatusreports.htm.
