Current and Planned Activity
Yesterday, firefighters continued to construct line directly on the fire’s edge where possible. In the West Fork of Hound Creek, crews extinguished areas of heat near the fire’s edge while aircraft dropped buckets of water to help slow the fire spread. Structure protection continued in the Sheep Creek area while structure assessment began in Cox Creek. Substantial support from aircraft, with 2 to 3 helicopters working the southeast and southwest portions of the fire with water drops. Firefighters working the night shift, from 7:00 PM to 11:00 AM, monitored fire activity in the southeast as well as in Sheep Creek and Novak Creek, providing point protection near structures as necessary.

Today, crews on the north edge of the fire will monitor constructed fireline and further secure the line as needed. Firefighters working the eastern portion will continue to construct fireline directly on the fire’s edge where possible both to the northwest and southwest of current containment line. In areas where the fire has reached structures, crews will continue to secure those areas by extinguishing any remaining areas of heat. Aviation will be used to support firefighting efforts on the ground by slowing the fire spread as visibility allows.
