The Texas Forest Service sent a firefighting crew on Sunday to help battle a wildfire in Virginia.

"The wildland fire response community is always standing ready to assist one another," Texas Forest Service fire chief Mark Stanford said.

The fire started June 26 after a lightning strike and has burned more than 1,100 acres in and around Shenandoah National Park near the Virginia and West Virginia border.  

Although the fire is about 20 percent contained, crews said it could be weeks before the fire is put out because of the difficult mountainous terrain.
