FLAGSTAFF, Ariz. -- A team of investigators from the U.S. Forest Service's law enforcement wing are working to determine the cause of a wildfire between Flagstaff and Sedona.
Coconino National Forest spokesman Brady Smith said federal officials could not reveal details of the investigation, but believe the fire is human-caused. The five-person team is at the scene of the blaze.
Smith said investigators have received about 80 tips from callers. It could still take months for them to pinpoint exactly how the fire began.
The Slide Fire has burned about 32 square miles and continues to grow, stifling tourism in parts of the Sedona area, which usually is busy with visitors this time of year.
Slide Rock State Park, one of Arizona's most-visited tourist spots, has been closed since the fire began May 20.
