DENALI PARK, Alaska: On Wednesday, June 17, Denali National Park and Preserve (Denali) received notification that a satellite had measured a heat detection from within the boundaries of the Park/Preserve. Upon notification, National Park Service (NPS) fire personnel coordinated with Bureau of Land Management Alaska Fire Service (BLM AFS) – Tanana Fire Management Zone staff to investigate. A detection aircraft was dispatched to the area, which is approximately 26 miles north of Kantishna, and west-north west of the confluence of the Bearpaw River and Moose Creek. Upon arrival, the aircraft observed a smoldering fire covering approximately 400 acres, creeping with isolated torching. The fire is burning in an area composed largely of tundra and black spruce. The fire (#248) has been named the Bearpaw Mountain Fire.
NPS and BLM AFS fire personnel will monitor the fire and allow it to continue burning to achieve land management objectives. Fire teams will enact Point/Zone Protection tactics for nearby structures. The closest NPS structure to the fire that is designated for protection is 8.9 miles to the west. The closest private structure is 3.5 miles to the east of the fire; NPS fire crews staged structure-protection resources at this site earlier today.
The fire is located within a Fire Management Option Area designated for Limited Protection.
Wildfires occurring within the Limited Management Option will be allowed to burn within predetermined areas. Periodic surveillance will be conducted to evaluate the need for action to protect human life or site-specific values. By allowing fire to spread naturally, a natural mosaic of fire footprint and intensity can be maintained. This option reduces both long-term risks and costs while sustaining a natural range of variation in plant composition and structure. (Alaska Interagency Wildland Fire Management Plan, p. 24)
This is the same general area where the first fire of Denali’s 2020 wildfire season, the Bearpaw River Fire (#145), was found on June 1. This fire was monitored by the NPS and declared out on June 10.
The satellite that found the heat detection is part of the National Oceanic and Atmospheric Association’s (NOAA) Visible Infrared Imaging Radiometer Suite (VIIRS). VIIRS is one of the key instruments onboard the Suomi National Polar-Orbiting Partnership (Suomi NPP) spacecraft, which was successfully launched on October 28, 2011. The VIIRS empowers operational environmental monitoring and numerical weather forecasting by providing sensor readings for more than twenty environmental data records; including clouds, sea surface temperature, ocean color, polar wind, vegetation fraction, aerosol, fire, snow and ice, vegetation, and other applications.
Fire in Alaska’s boreal forest is an essential process that restores ecosystem health and helps maintain species diversity. The NPS works closely with its interagency partners, neighboring communities, and other stakeholders to balance the risks and benefits of wildland fire when making decisions on fire management. Landowners can assist in these efforts, and decrease the potential risk to their property, by taking steps to make cabins and other structures more defensible against wildfire. The public can find more information about defensible space and being ready for wildfire by visiting www.forestry.alaska.gov/fire/firewise or reading this Alaska Firewise pamphlet
