Interior Releases Knowles Fire Report: Four Firefighter Deaths Traced to Extraordinary Fire Behavior, Strained Communications and Overlapping Factors
The U.S. Department of the Interior (DOI) on November 12 released the findings of the Knowles Fire Serious Accident Investigation Report: on June 27, 2026, an accident on the Knowles Fire in western Colorado killed four federal wildland firefighters and injured a fifth. The investigation was conducted jointly by the U.S. Wildland Fire Service and the U.S. Forest Service.
According to the report, the interagency helitack crew was engaged in initial attack operations on the Knowles and Gore fires when it was overtaken by the larger Snyder Fire, which crossed complex canyon and mesa terrain at a speed and scale not previously observed in wildfires in the area, in a burnover incident. The four fallen firefighters were Emily Barker, Nick Hutcherson, Nathan Matthews and Sydney Watson; another crew member was injured.
The investigation found that the tragedy resulted from the cumulative interaction of complex factors, including extraordinary fire behavior, strained communications, incomplete situational awareness, jurisdictional complexity, gaps in aerial supervision and extreme operational tempo. The findings identify opportunities to improve communications, real-time fire observation, airspace awareness, dispatch coordination and situational awareness.
Secretary of the Interior Doug Burgum said the safety of wildland firefighters will always be the department's highest priority, that it is DOI's duty to always remember the four fallen firefighters' service and sacrifice, and that the department dedicates itself to applying the lessons of the report in their honor. Deputy Secretary of the Interior Kate MacGregor said the department would search for every modern technological improvement to better support firefighters, and that the report will help inform that work. U.S. Wildland Fire Service Chief Brian Fennessy said the investigation remained committed to following the facts wherever they led, and that the report provides insights into the contributing factors that can help improve the safety of firefighters across the wildland fire community.
