A wildfire Wednesday forced the evacuation of hikers and closed trails in the Kolob Canyons area of Zion National Park.
The Cliff fire started Tuesday and has grown to about 200 acres, National Parks Service spokesman David Eaker reported. It is located on Black Ridge, about two miles east of Interstate 15 and six miles south of Kolob Canyons visitor center.
The Kolob Canyons Scenic Drive and all trails leading from it are closed, Eaker reported. The Hop Valley Trail, along the Kolob Terrace Road, is also closed.
Park rangers evacuated an unknown number of hikers from the La Verkin Creek trail, Eaker said.
The lightning-caused fire has been moving northeast into the park's La Verkin Creek drainage.
Fire crews are working on containing the fire, but it is burning in a difficult area to reach, Eaker said. Helicopters were also dropping water on the fire.
