Authorities in the southwestern Colorado county of La Plata have ordered residents to evacuate another 304 homes as firefighters battle a wildfire north of Durango.

County officials issued the order Friday for residents living along U.S. Highway 550 north of the fire near the town of Hermosa, about 15 miles (24 kilometers) north of Durango.

Residents have until 4 p.m. to leave the area so firefighters can check the advance of the northeast flank of the fire.

Nearly 675 firefighters backed by air support are attacking the 11-square-mile (29-square-kilometer) blaze, which already had forced the evacuation of more than 1,000 homes. No homes have been reported destroyed.

The fire started June 1 and is 10 percent contained. Its cause is unknown.
