UPDATE: Cause of Avon wildfire still under investigation

The wildfire that began late Friday night, June 12,  just north of Avon was 100 percent contained by early Saturday evening, according to David Hallac, superintendent of the Cape Hatteras National Seashore.

Hallac said the total area burned by the blaze was somewhere between 15 and 20 acres.  The cause is still undetermined, though the Park Service will continue investigating.

Firefighters and other emergency responders were leaving the scene by about 6 p.m. Park Service personnel, he said, checked on the fire intermittently overnight, and the Park Service and the U.S. Fish and Wildlife Service flew over the area this morning to check for any hotspots of fire.

At one point early Saturday morning, the fire threatened both the historic Little Kinnakeet U.S. Life-Saving Station and Cape Hatteras Electric Cooperative power poles.  Highway 12 was closed to traffic for about four hours overnight, but reopened about 5:40 a.m.
