OAK CREEK CANYON, Ariz. (AP) More crews are en route to northern Arizona to battle a wind-whipped 450-acre wildfire near Slide Rock State Park in scenic Oak Creek Canyon.
The blaze has forced the evacuations of 100 threatened businesses and homes in a 2-mile stretch north of the state park.
About 100 firefighters and other personnel were assigned to the fire on Tuesday, and National Forest officials say four additional Hotshot crews and a top-level fire management team are scheduled to arrive Wednesday.
The Slide Fire started Tuesday afternoon and authorities believe it was human-caused.
There are no reports so far of injuries or structures burned.
State Route Highway 89A is closed through the steep-walled canyon between Sedona and Flagstaff.
Slide Rock State Park is a popular recreation area due its natural rock water slides.
