No significant activity occurred in the fire area last night. Yesterday’s outstanding work in this difficult terrain resulted in increasing the containment of the fire to 79%. Weather and fire conditions yesterday afternoon allowed firefighters to conduct a burning operation which successfully reduced interior unburned fuels and secured a portion of the eastern perimeter of the fire.
Residents should expect to continue to see increased smoke activity today due to back burn operations by the firefighters.
The Bison and Pika neighborhoods remain closed except to residents. Flagstaff Road is open, but firefighters are still using this road, so residents need to keep the road clear for their equipment.

Today crews completed extinguishing hot spots up to 100 feet inside the fire’s western perimeter. Crews assigned to continue construction of fireline along the north-east, east, and south-east edges made significant progress throughout the day as well. Weather and fire conditions in the afternoon allowed firefighters to conduct a burning operation which successfully reduced interior unburned fuels and secured a portion of the eastern perimeter of the fire. This burning operation was approximately 25 acres in size, and produced visible smoke from the Boulder area.
Residents within local communities should expect to continue to see occasional flare-ups during the night, as well as lingering smoke from within the fire area. These flare-ups are a result of small, unburned islands of fuel, including single trees, well within the fire’s interior. They do not pose a threat to the fire’s perimeter. Additionally, two engines will be assigned to the fire tonight to patrol the area and watch for any increase in fire activity.

Firefighting crews will be igniting a "back burn" within the fire perimeter that will produce heavy smoke throughout the afternoon and may cause concern for residents and visitors. The back burn is a planned activity where flame is applied to fuels in the fire zone that have not yet burned in order to strengthen the perimeter around the fire.
A lot of smoke will be visible, but the fire is not flaring up on its own. Experienced crews are coordinating this effort with the intent of decreasing the potential for the fire to grow outside the contained areas.
The heavy smoke visible in the Boulder Valley and foothills is NOT from local fires. There are many other fires burning in the region which have caused smoke to setlle in the area. Smoke from non-local fires is likely to remain visible for several days.
