Alder Creek, Trail Creek, Christensen, and Black Mountain Fire Update August 17, 2021

Alder Creek

Size: 13,984 Acres

Containment: 10%

Location: 7 miles west of

Wise River, MT

Start Date: July 8, 2021

Cause: Unknown

Total personnel: 279


Alder Creek Fire: Smoke and cloud cover limited fire behavior across the area and

kept movement slower than expected. Aircraft were able to drop water on the Deno

Creek and Stine Ridge areas to keep heat down on the southeast section of the fire.

Logging operations continued to remove downed trees from surrounding roads. Crews also

tested and ran water pumps for structure protection near the Pioneer Scenic Byway.



Trail Creek

Size: 38,845 Acres

Containment: 26%

Location: 20 miles west of

Wisdom, MT

Start Date: July 8, 2021

Cause: Lightning

Total personnel: 273


Trail Creek Fire: Aircraft dropped water on hot spots that remained in areas north of the

Big Hole Battlefield. Fire could move slowly through Salix Creek, but will run into wet

meadow barriers. Heat remains in the Gory Creek drainage with a little movement to the

south. The fire moved off of Three Mile Ridge and backed into the bottom of the Nez Perce

drainage. There will be an increase in firefighter presence in the area between Gibbonsville

and Three Mile Creek to ensure the fire doesn’t cross Gibbonsville Rd. Crews worked to

improve defensive lines around the fire with lookouts posted to identify fire growth to the

west. This early detection allows crews to take swift suppression actions.



Christensen

Size: 11,012 Acres

Containment: 10%

Location: 12 miles west of Wise

River, MT

Start Date: July 16, 2021

Cause: Unknown

Total personnel: 52


Christensen Fire: Crews took advantage of the weather conditions to continue

constructing lines on the northwest side of the fire. These defensive lines near Highway 43

are nearly complete. Fire movement was contained to the interior of the fire. Due to the

incoming cold front, fire growth is expected to be minimal through Wednesday.
