Northern Rockies Complex Incident Management Team 3

#DerbyFire Ops Update Monday morning, Aug. 28, 2025. Philip Knaub, Operations Sections Chief, discusses firefighting tactics on the Derby Fire. Sunbreaks are rekindling smoldering conifer trees at higher elevations within the fire perimeter and smoke will be visible during periods of sunshine today. Heat remains despite the rain. Firefighters are building secondary control lines on the eastern side of the fire where hazardous terrain, snags, and heavier fuel types make safe access more difficult. Control line construction continues on the southeastern fire edge. Firefighters are mopping up (removing and extinguishing burning vegetation) and patrolling completed control lines. On the west side, incident managers are evaluating a potential spike camp location for smokejumpers to more easily access the most active part of the fire. We expect to see an increase in containment over the next few days.
