A fire in Shenandoah National Park in Virginia has burned through more than 5,600 acres and closed a portion of the Appalachian Trail.

Crews with the Virginia Department of Forestry worked Wednesday to contain the wildfire. There have been no reports of injuries.

Forestry officials say the wildfire has steadily grown since it was reported over the weekend. They say the cause is unknown.

The fire has caused a section of the Appalachian Trail in Virginia between Powell Gap and Doyles River Overlook. The trail runs from Georgia to Maine.
