Alder Creek Fire

Current Size: 5,676 Acres

Current Containment: 3%

Resources Assigned:

Total personnel: 308

Engines: 16

Hand crews: 6

Alder Creek Fire: The fire experienced minimal growth yesterday, slowly moving

towards the Hwy 43 and Pioneer Scenic Byway corridors. Crews focused on

stopping the main fire by using tactical fire to remove burnable fuels, but rain has

slowed firing operations. Fire engines and hand crews continue to hold and

improve containment lines and protect structures today. Fire growth is expected

to be slower today, however potential high winds accompanying thunderstorms

may increase fire spread.

Trail Creek Fire

Current Containment: 0%

Resources Assigned:

Total personnel: 126

Engines: 4

Hand Crews: 3

Trail Creek Fire: The fire grew minimally yesterday, continuing to push slowly east

along the Hwy 43 corridor. Strategic firing at the Big Hole National Battlefield

protected adjacent private structures and the Visitor Center. Firefighters will

continue holding lines and working hotspots. South of Hwy 43, the plan is to hold

the fire on Butler Creek where it intersects with Foothills Rd. Firefighters are

working to stop the fire from spreading to the Continental Divide. Fire growth is

expected to be slower today, however potential high winds accompanying

thunderstorms may increase fire spread.
