Fire crews are searching for hotspots by air using heat-sensing equipment above a northwestern Minnesota wildfire.
Crews in a helicopter used the hand-held sensor to find smoldering fires in the 7,100 acres burned by the wildfire which started Tuesday.
A Minnesota Incident Command System spokeswoman said the fire is not growing and no additional structures have been lost since the 55 homes and buildings were destroyed earlier in the week.
The fire is 65 percent contained as firefighters make progress in securing the containment lines around the fire perimeter. The cause of the fire remains under investigation and no injuries have been reported.
