Yesterday, improved road conditions allowed firefighters to get out to assess the snow effects on both the Cameron Peak Fire and the Thompson Zone of the East Troublesome Fire in Rocky Mountain National Park. Firefighters were able to access the southern perimeter of the Thompson Zone and began constructing fireline directly along the fire edge. 

Road conditions were still poor and prevented access to the area below Storm Mountain. Pingree Park reported 27 inches of snow but the snow accumulation was far less in the area to the northwest due to the forest canopy that diminished the amount of snow reaching the ground. This is an area where the fire is smoldering and producing smoke. Firefighters accessed the Buckhorn Rd area to check firelines and hope to have that area contained over the next few days. 

Today, firefighters will continue to improve indirect firelines north of the Thompson Zone fire perimeter that were initiated previously. Fire managers will continue to look at options for direct line construction on the east perimeter to prevent the fire from spreading into Estes Park. 

On the Cameron Peak Fire, fire managers will try to get into the area south of Storm Mountain and around The Retreat to look at options for direct and indirect fireline to secure that section of the perimeter. The fire perimeter north of Cedar Park is looking good and will likely reach containment later today. Fire managers will assess the fire above Glen Haven and the slop-over across the North Fork Trail to look at direct and indirect options to secure the fire edge. Air operations will continue to monitor the area above Pingree Park and to the west in the Comanche Reservoir area. For the rest of the fire, firefighters will continue to patrol the fire edge and start hauling out equipment that is no longer needed and begin suppression repair work.

Significant Events




Planned Actions

- Monitor heat in the South Pingree Proper area and develop trigger points and plans for re-engaging suppression activities.

- Monitor heat in the Cedar Park, and Glen Haven areas and develop trigger points and plans for re-engaging suppression activities.

- Establish and maintain resource accountability for all resources, including contact information (phone, email, etc.) and RON location, as resources were spread out during the recent winter storm event.

-Locate and document all accountable property.

-Once safe access is reestablished, access suppression efforts needed to secure fire edge in preparation for warming and drying conditions.

-Determine resource and equipment needs for continued suppression activities. Provide estimated timeline for start and duration needed.

- Backhaul all unnecessary equipment and supplies.

- Determine resource and equipment needs for suppression repair. Provide estimated timeline for start and duration needed.

Projected Incident Activity

12 hours: Continued warming with increasing snow melt. Smoldering may accelerate to marginal surface spread in the Pingree Park, Cedar Park, North Fork and Thompson Zone areas.

24 hours: Continued warming with increasing snow melt. Smoldering may accelerate to marginal surface spread in the Pingree Park, Cedar Park, North Fork and Thompson Zone areas.
