Fuels Involved

Timber stands consist of a mix of Fir, Spruce, and Pine. Heavy fuels are very receptive to spotting due to below average fuel moistures.

Significant Events

The fire continued to be active today with increased winds along with continued warming and drying trend.Observed fire behavior was backing and flanking with tree torching.


Planned Actions

Use aviation resources as needed to keep fire in check in the Pat and Drake Creek drainage. Crews will construct new primary indirect lines and strengthen existing contingency on the southern portion of the fire. Utilization of heavy equipment will greatly help in making progress with line construction.

Projected Incident Activity

Predicted weather is expected to produce areas of active fire behavior with spread continuing through available fuels. The fire will continue to back to the northwest. Burning will continue in unburned fuels in the Drake Creek area.Afternoon downslope winds will pose a threat for the fire to push south in Eightmile Creek.
