A wildfire that has been a potential threat to a highway serving the Grand Canyon's North Rim has spread due to dry and windy conditions.
An incident management team says flames jumped between tree tops Saturday, moving rapidly at times to the northeast in the Saddle Mountain Wilderness.
However, firefighters continue to keep the blaze at bay to the north and east of State Route Highway 67.
The fire started June 29 and has burned 11,382 acres.
Crews will spend Sunday focused on securing the fire perimeter. Helicopters will continue to drop water as needed.
All forest areas south of Tater Ridge Road between Highway 67 and House Rock Valley Road were closed, though the North Rim Visitor Center and Highway 67 remained open, officials said.
The lightning-caused fire is still at zero containment.
UPDATE: A previous version of this story incorrectly stated that the North Rim Visitor Center was closed. ABC15 regrets the error.
