SUFFOLK (AP) -- Underground fires continue to smolder in the Great Dismal Swamp National Wildlife Refuge.
An interagency team fighting the fires says Hurricane Irene dumped an estimated 1.7 billion gallons of water on the fire area. The drenching doused the surface fire that was sparked by lightning on Aug. 4.
Fire information officer John Bearer says the fire is still burning in the peat. As the swamp dries out, more hot spots are appearing.
As of Wednesday, crews had contained 90 percent of the fire. Incident commander Mike Dueitt says mop-up operations will continue throughout Wednesday.
The refuge remains closed to the public. Dueitt says refuge crews are working to reopen trails.
The fire has burned more than 6,300 acres in Virginia and North Carolina.
The Dismal Swamp State Park will remain closed through Sept. 8. The office, boardwalk and canal trail will open on Sept. 9.
