Fire Overview Map Sept 16Image options: [ Full Size ]

 When the Boundary Fire started on August 10th in the Frank Church River of No Return Wilderness, it escaped initial attack suppression efforts by firefighters.  Fuel moisture in the trees, logs, and shrubs is at an unprecedented low due to extended drought.  That means fires can exhibit explosive fire behavior very easily in the presence of wind and high termperatures.  The Fire was able to quickly run uphill in very steep terrain.  Given the amount of fire activity in the West in 2021, where this Fire is burning, and the limited availability of resources, the Salmon-Challis National Forest reconsidered their objectives.  It was decided that the best approach was to protect values at risk, meaning private property and infrastructure for both private and federal landowners.

Estimated Containment DateSaturday October 30th, 2021 approx. 10:00 PM
Fuels Involved

Mixed conifer, sage, grass, heavy dead and down, burn scars. Fuel models are timber, brush, and short grass.

Significant Events

Containment figure is actually completion of incident objectives. Smoldering and creeping was observed in the Scarface area, Little Soldier Lookout, and Sheep Creek. Very little to no smoke observed by air attack on most of the fire area.


Planned Actions

Structure protection and preparatory work has begun in Pistol Creek and Indian Creek GS. Preparatory work will continue on the FS 579 Road. Continue to assess values at risk for point and structure

protection. Continue to locate and triage values at risk not previously identified. Continue consultation, development, and refinement of PACE plan with Boise NF for coordination in the event the Boundary Fire crosses jurisdictional boundaries. Begin backhaul of any unnecessary supplies and equipment from spike camps.

Projected Incident Activity

Smoldering and creeping expected in all groups with minimal fire behavior for this time frame. The below conditions exist as weather warms and dries:

Scarface Group: Continued fire activity near the tributaries of Middle Fork Salmon River, Little Soldier Creek, and Marble Creek with fire spread northwest. Backing fire into Thomas Creek and Little Creek towards the Middle Fork of Salmon River, potentially impacting Sater Cabin and Thomas Creek Airstrip.

Seafoam Group: Continued burning in the eastern portion of the Seafoam area with active fire in Corduroy Creek drainage spreading northeast. Fire continues to impact the Mountain King Mine vicinity. Active fire will continue along Seafoam Creek.

Sulphur Group: Potential for backing and flanking south of Sulfur Creek and east of Silver Moon Creek, impacting Sulphur Creek Ranch. Active backing into the wind on Blue Bunch Mountain

southwest towards the Blue Bunch/Bear Valley Creek and Boundary Creek. Fire will spread in Middle Fork Salmon drainage.

Pistol Group: Fire continues to back west and southwest, down slope from the headwaters of

Cabin Creek drainage towards Rapid River drainage.

Predicted increase in fire behavior with the forecasted winds.


Containment actually refers to completion of incident objectives, not constructed line. Boundary Creek, Indian Creek, and Thomas Creek launch sites are closed to boaters until further notice.

Current Weather

Weather Concerns

Dry stable air will remain in the fire area for two more days. Increasing temperature and decreasing RH values will continue throughout the remainder of the week and into the weekend. Increased fire behavior is expected to start around Friday with relative humidity reaching the teens. Forecasted winds will be breezy /windy Sunday, Monday, and Tuesday.
