News Release Date: July 27, 2025
MOOSE, Wyo.–Teton Interagency Fire crews continued suppression efforts Sunday on the Signal Flat Fire, which remains estimated at 7.8 acres and is now 100% contained. The lightning-caused fire was first reported Saturday, July 26, and is burning in mixed conifer forest near Signal Mountain in Grand Teton National Park.
Local crews were assisted again today by a 20-person USDA Forest Service Type 2 crew from Helena, Montana. The additional firefighters were recently released from another incident and reassigned here to aid with area fuels reduction work. They quickly pivoted to initial attack yesterday to assist with fire suppression, adding to the success in limiting fire spread.
Today’s efforts focused on securing and improving fire lines dug by firefighters yesterday. From there, crews worked into the interior of the fire to address any areas holding heat and to look for spotting potential. With gusty winds in the area, firefighters diligently watched for burning embers that could be transported from the main fire to unburned areas.
A helicopter flew hoses and portable pumps to the site this morning, allowing firefighters to draft and use water from a nearby pond to cool remaining hot spots. By early afternoon, hoses were placed around the fire's full perimeter. Aerial resources were also used to drop water as needed to address spotting detected yesterday.
Signal Mountain Road remains closed to public use due to fire vehicle traffic on the steep and winding road.
With hot and dry weather forecast for the next few days, fire officials remind all public land users be cautious with any possible source of ignition. Campfires need to be drowned and stirred repeatedly until cool to the touch before campers leave fires unattended overnight or depart from the site.
