Fire officials say the Honey Prairie fire, which started April 30, has barely grown since it surpassed 300,000 acres a month ago. It has now burned a total of 303,172 acres - or about 473 square miles - mostly inside the boundaries of the Okefenokee National Wildlife Refuge.
Refuge manager Curt McCasland says summer thunderstorms have been too sporadic to put the fire out. Firefighters believe it's now burning into the dry peat beds of the swamp, which have plenty of fuel for the fire to keep smoldering beneath the ground.
There are still 109 firefighters and support personnel assigned to the wildfire, but officials say only prolonged, soaking rain will extinguish it.
