Crew holding line during firing ops

The Boulder Fire was started by lightning on the evening of July 24, 2024, approximately 1 mile to the southeast of Tripod Lookout. Fire crews responded immediately. Steep terrain, difficult access and unfavorable weather conditions encouraged fire spread. The Boise National Forest continued to manage the fire until a Complex Incident Management Team was requested.

Great Basin Team 2 assumed command of the Boulder Fire at 6am on Aug 10, 2024 and will manage the Boulder Fire, the Snag Fire and Dollar Fire on the Boise National Forest as well as the Wolf Creek Fire that started on the Payette National Forest and has spread to the Boise National Forest. All of these fires, along with a number of others were started by the same series of thunder storms on the 24th and 25th of July. 

Currently no evacuations have been ordered, road closures are in effect and please avoid the fire area so that fire suppression efforts are not impacted. https://www.fs.usda.gov/managing-land/fire/uas/if-you-fly

Flanking

Active fire behavior was observed throughout the night and into the day, with surface burning of timber/understory, and isolated torching and spotting.

Outlook
Planned Actions

The South Flank will continue to hold and improve with hose lays and direct tactics. Crews will continue to mop-up along dozer lines and evaluate opportunities for direct engagement of the fire edge. The east flank will continue with firing operations along dozer line and existing roads.

Projected Incident Activity

Tonight: The fire will continue to burn east into the South Fork of Fawn Creek and toward the following values: private structures, timber sales, and other cultural/resource values, continue north in Fawn Creek, northeast towards Grassy Flat; light observed fire behavior west on Tripod Peak towards Tripod lookout due to unseasonably high ERCs and poor RH recovery. Spotting will be likely. Light fire behavior is expected to the south towards Boulder Creek. Outflow winds from thunderstorms could increase fire behavior.

Remarks

This incident in being managed by GBT2 along with five other incidents (Wolf Creek, Snag, Dollar, and Goat).
