The Alder Creek Fire started on July 8, 2021 approximately 7 miles West of Wise River, Montana, in the Beaverhead-Deerlodge National Forest. The cause of the Alder Creek Fire has not been determined. The fire terrain is made up of forest timber with 2 feet high underbrush and heavy fuel loads of dead and down Lodgepole Pine. The surrounding valleys are characterized by short sage and grass mix. Fire crews are concentrating their efforts on constructing indirect containment lines, while providing structure protection on existing cabins and sites along the Wise River and Pioneer Mountains Scenic Byway.
The fire is being managed by the Southwest Type 1 Team #1, Incident Commander Alan Sinclair.
Forest Closure Orders are in effect for the fire area. Please see up to date closure order at Beaverhead-Deerlodge NF: Beaverhead-Deerlodge NF Closure.

Timber (Litter and Understory)
Brush (2 feet)
Heavy fuel loading of dead and down lodgepole Pine. Valleys can be characterized as short sage and grass mix.
Minimal fire activity with backing, creeping and smoldering.
Rainfall and high fuel moisture has limited fire behavior.
Structure protection measures are in place and daily exercise of equipment and plans will take place. Resources are updating Collector and cataloging accountable property daily. Resources will remove some structure protection equipment, where applicable, as there are areas where the fire no longer remains a threat due to successful indirect line construction and burnout. Primary, alternate, and
contingency are in place, however line construction will continue on the primary containment line over the next 7 days.
Structure protection measures are in place and daily exercise of equipment and plans will take place. Resources are updating Collector and cataloging accountable property daily. Prepping of the 73 road will continue. Primary, alternate, and contingency lines are in place
and identified on mapping products.
Structure protection measures are in place and daily exercise of equipment and plans will take place. Resources are actively constructing indirect fireline to tie in with Kilo/Oscar in a coordinated effort. This
will continue over the next 7 days. Alternate and contingency lines have been identified.
|Projected Incident Activity|
12 hours: Smoldering fire behavior is expected overnight.
24 hours: A day of drying will bring fuels into a condition to support fire. Expect to see low to moderate with a brief period of active fire behavior in the afternoon.
48 hours: Moderate to active fire behavior is expected with the drying conditions. Eastward movement is expected.
72 hours: Higher humidity will once again lower fire behavior to moderate with a chance of active fire behavior with sunshine and wind.
Anticipated after 72 hours: More moisture will keep fire behavior moderate to low. Very little movement is expected.
Fire has potential for large growth and will threaten numerous structures and affect HWY 43 and Pioneer Scenic Byway. It will cross multiple jurisdictions.
Monsoonal moisture pivoted across southwest Montana today, bringing widely scattered showers and thunderstorms. Temperatures warmed into the 60s up on ridge tops and 70s down in the valleys. The moist airmass and additional rainfall keep afternoon relative humidity values in the 50 to 60% range.
Tomorrow will be significantly drier, with warmer conditions. Deep mixing will prevail as this drier airmass moves into the region, with prevailing west to northwest winds. There will be enough lingering mid-level moisture to favor the development of high-based cumulus in the afternoon.
