Mandatory evacuation orders in effect as 1,000-acre wildfire threatens Grand Canyon's North Rim

The North Rim of the Grand Canyon is temporarily closed as mandatory evacuation orders remain in effect due to a wildfire near the park. 

The White Sage Fire, near Jacob Lake, prompted the National Park Service to evacuate all North Rim visitors "immediately" on Thursday night. 

As of Thursday night, the fire had burned about 1,000 acres and remains active with no containment, according to a report from the U.S. Department of the Interior Bureau of Land Management (BLM).

Two single-engine air tankers based in Mesquite delivered fire retardant to assist with initial suppression efforts before dark, according to the report. Crews worked through the night, making progress on the south, east and northeast flanks.

Air attack arrived on scene Thursday and aircraft continued to support ground crews, officials said. A Complex Incident Management Team was ordered.

Highway 89A to Fredonia is closed in both directions at mile marker 595 due to the fire, with no estimated reopening time, according to the Arizona Department of Transportation.

Highway 89A east to Page remains open, according to the park service.
