LARIMER COUNTY, Colo. — Crews grew containment on the Cameron Peak Fire to 30% by Thursday morning, up from 22%, after a day of good weather conditions allowed firefighters to attack the sprawling fire more directly.
The fire in western Larimer County was at 125,006 acres on Thursday, holding steady from its acreage Wednesday.
Hand crews worked with air support to attack stretches of the fire in the Long Draw area and on the northwest side of the fire. On Thursday, crews were expected to extend fire lines along the perimeter of the fire and protect structures in the area.
Dry fuels and shifting winds remained a concern Thursday.
Wildfire smoke from the Cameron Peak Fire and Mullen Fire, along with other western wildfires, created poor air quality conditions across Colorado’s Front Range Wednesday.
