The Tunnel Fire has been burning northeast of Flagstaff for more than a week and has reached nearly 20,000 acres. Hundreds of personnel have steadily increased containment in recent days to about 30%. The massive effort is one of several ongoing concurrently in the Southwest where multiple wildfires are burning during an unusually early time in the region’s fire season. KNAU’s Ryan Heinsius spoke with Tunnel Fire Information Officer Chris Barth about the logistics of fighting the fire and how its timing may have affected suppression efforts.
