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 deep duff, 1000 hour fuels and stump holes. Fine fuels may become available to fire today or later in the week.


Planned Actions

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

Div B: As weather permits, implement suppression repair as needed. Patrol Elk Meadows road and the 373B road, taking appropriate action when needed to maintain ingress and egress.

(7) Area burned based on improved data and previous perimeters. Infrared data as of September 24th, shows no perimeter movement for the past week.

(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.
