Yesterday’s warm, sunny conditions contributed to increased snow melt over the fire area, improving access for firefighter engagement. On the Thompson Zone of the East Troublesome Fire in Rocky Mountain National Park, firefighters continued to improve firelines on the southern perimeter, prepared indirect line to the north that will tie into the Bear Lake Rd, monitored the snow melt for opportunities to get to the fire edge and pulled out equipment that is no longer needed. 

On the south side of the Cameron Peak Fire, fire managers continued to evaluate areas along the southern perimeter to determine access options and containment strategies.  This includes Cedar Park, Storm Mountain, The Retreat, Glen Haven, the North Fork Trail slop-over, and the Pingree Park and CSU Mountain Campus areas. Assessment of containment lines on the east perimeter and around the Otter spot fire north of Masonville is ongoing to determine and begin necessary repair work. A drone was flown over the fire perimeter along the Buckhorn Rd (44H) to assess conditions and showed a lot of snow on the north-facing slopes in that area. The fireline that was in question near Bellaire Lake has been confirmed contained. 

A cold front moved into the area in the pre-dawn hours this morning with gusty winds up to 50 mph. Unlike previous wind events on this fire, the duration will be shorter and the overall conditions – temperatures, relative humidities, fuels receptive to burning – are less severe. The winds will accelerate snow melt and drying, which will improve firefighter access. It will also expose more of the fire edge and show where heat remains. This will be an advantage to fire managers as they prioritize where to focus resources to build direct and indirect fireline and reinforce existing lines during today’s activities on the Thompson Zone and the southern fire perimeter of the Cameron Peak Fire.
