Derby Fire: No significant growth overnight and less active today

There was no significant growth on the Derby Fire north of Dotsero, CO overnight. Night operations focused on structure protection in the Sweetwater Canyon area. The fire has been less active today.

Hotshot crews are working to construct and improve fireline directly adjacent to the fire’s edge along the southwest side. Conditions this afternoon have allowed firefighters to conduct a burnout operation on the southern edge of the fire, as discussed in the video here. Smoke may be more visible during the operation. Air resources are on hand for support.
