Areas of Big Bend National Park are shut down as fire crews continue working to extinguish a fire that spread more than 1,000 acres as of midday on Monday.

The Crown Mountain fire is believed to have been started by lightning Sunday near the Chisos Mountains area, according to park officials. On Monday, all facilities in the Chisos Basis were closed to the public.

The National Park Service has closed the following areas to all use:

>>Juniper Canyon and Pine Canyon roads and campsites

>> Outer Mountain Loop Trails and camping (Dodson, Juniper Canyon and Blue Creek)

>> Chisos Mountains Trails and campgrounds

Public information officer Jennette Jurado said firefighters are on scene and additional resources are en route.

Although the Chisos Basin Campground has been evacuated, it was not threatened by the wildland fire. Officials said the area is being used so fire crews and equipment can be staged there. The Chisos Mountains Lodge also chose to evacuate the lodge and restaurant as a precaution.

Alternate camping is available at Cottonwood and Rio Grande Village campgrounds, officials said. Panther Junction Visitor Center is open and is offering regular services during regular business hours of 9 a.m. to 5 p.m.

A recorded message of current updates on closures is available by calling 432-477-2576. More information will be given when it becomes available.
