â??The fire started burning in Oak Creek Canyon near Slide Rock State Park just before 4 p.m., said Brady Smith, a Coconino National Forest spokesman.
The flames are moving to the north, and evacuations are in place north of Slide Rock, according to an incident update. Timber and fuel treatments in the area are burning.
The fire is not spreading as much to the west.
"I see smoke and it looks like the smoke is thicker in some areas more than others," said Milena Pfeiffer, owner of Canyon Wren Cabins, located about two miles south of Slide Rock State Park.
The cause of the fire is still unknown.
The American Red Cross Grand Canyon Chapter has mobilized volunteers and supplies and has opened a shelter for evacuees of the Slide Fire at Sinagua Middle School, 3950 E. Butler Ave., in Flagstaff.
The Red Cross shelter is not accepting pets. A separate pet shelter is set up nearby at the Coconino Humane Association, 3501 E. Butler Ave.
Slide Rock State Park is a favorite destination in the summer. People visit in droves to slide down the naturally formed sandstone water slides. The 43-acre park is located 7 miles north of uptown Sedona. The West Fork of Oak Creek, with its towering cliffs, meandering stream bed and lush vegetation, is one of the most popular hikes in the state
The Midgley Bridge area about 1.5 miles north of uptown is another popular stop and is home to three popular trails â?? Wilson Canyon, Wilson Mountain and Huckaby.
Arizona 89A is closed for 12 miles north of Sedona due to the fire and runs from Midgley Bridge to Junipine Circle, Smith said.
Officials are asking residents to take an alternative route of Arizona 179 east to the Interstate 17.
