Incident DescriptionThis Will Be A Long-duration Wildfire Which Has Affected The Developed Corridors Of Highways 12 & 93.

Current Situation

Total Personnel246
Size53,902 Acres
Percent of Perimeter Contained87%
Estimated Containment DateTuesday October 31st, 2017 approx. 12:00 AM
Fuels Involved

Above 7,000 feet, generally sparse and /or patchy subalpine fir with dead Whitebark pine. Below 7,000 feet, mixed conifers that vary in composition, density, and dead/down levels. With more Lodgepole pine, higher intensity burning and with more Larch, less intense burning. Lower elevations near containment lines are Ponderosa pine with grass understory.

Significant Events

Minimal smoldering. Fire behavior limited to smoldering in deep duff, stump holes and 1000 hour fuels. Snow is present down to mid-level elevations of the fire. Precipitation occurred again over the fire area yesterday and today.


Planned Actions

Div A: As weather permits, identify and implement suppression repair as needed.

Div B,C,E,F,H,J,L: Continue suppression repair efforts as weather and risk management actions allow.

Collaboration with BAER team as they continue assessments throughout the week.

Fire managers will continue to assess for opportunities to mitigate risk while monitoring smoldering fire activity and making progress on containment or suppression repair.

Projected Incident Activity

12 hours - Cloudy and cold with light precipitation. Minimal fire behavior.

24 hours - Cloudy and cold with chance of rain and snow. Low humidity of 50%. Fire behavior will be minimal. Fuel moistures of 100 and 1000 hour fuels will rise. Fine and 10 hour fuels will be saturated and unable to carry fire. Fire behavior will be limited to the consumption of large fuels and smoldering in stump holes and deep duff.


(7) Area burned based on improved data and previous perimeters.

(8,9) Full suppression is the strategy used on all parts of the perimeter where high values resources are threatened. This

includes the west, north and east side of the fire. The southern portion of the perimeter which does not threaten private land will be managed with a confine strategy, using natural barriers, constructed fire line, retardant and water drops.

A large part of this portion of the perimeter is in the Selway-Bitterroot Wilderness. The ratio between the strategies will be calculated based on perimeter progression. The amount of contained fire perimeter will be calculated accordingly.

There are no Evacuation Orders or Evacuation Warnings at this time.

Unified command was dissolved Monday, September 18th.

Reported containment reflects portions of the perimeter where the fire has been engaged at control lines and has been contained. A portion of the fire along the southern part of the perimeter will not reach man-made containment lines. This portion will be confined by natural barriers and weather conditions not conducive to fire spread.

Current Weather

Weather Concerns

Fuel moistures are rising from the precipitation and high humidity. Snow levels are predicted to drop to lower elevations around 5000 feet. Minimal fire behavior should continue to decline during the week.
