The Boundary fire, 223 acres, is located approximately 4miles north of West Yellowstone and is 1⁄4 mile inside the park boundary. Firefighters continue to work to the south and southwest constructing hand line directly along the fire's edge. A couple smaller spot fires were picked up Tuesday and crews worked to get handline around those spot fires. To the north of the fire, personnel put in direct fire line. Current daily smoke inversions have been limiting aircraft's ability to fly in the early morning.
Firefighters have made good progress on the 1 acre Thumb Fire, reported on August 15. Yesterday a 7-person load of smokejumpers worked on establishing a perimeter around the fire. There are heavy dead and down trees that are making the mop up progress challenging. Despite the small size, it will take several days to get full containment. It is located near Duck Lake, just north of the West Thumb junction and is within 0.5 miles from the Grand Loop road.The cause of the fire is undetermined.
For several days, the Maple and Buffalo fires have showed a significant increase in fire growth and produced smoke columns that were visible to surrounding communities and park visitors. Anticipate more smoke today, as weather andfuel conditions will produce additional growth. Park managers are working with the Custer Gallatin NationaForest to notify outfitters and guides about trail closures near the Buffalo fire.
All roads leading into and through the park are open. All park visitor facilities, including park concession-operated services, and businesses in surrounding communities are not impacted by the fires and remain open. Fire information officers will be staffing information boards around the park and will able to answer questions from visitors.
Stage 1 Fire Restrictions are in place within Yellowstone National Park
