This is an areial picture from the Chesterfield Rt 288 fire from yesterday. The very dark areas are portions of the young pine plantation that were burned so hot that few if any trees in those areas will survive.
The pictures below are from a wildfire in Mecklenburg County that started from an debris burn that "got away". Several acres and 2 cottages later the Department of Forestry and local fire Departments stoped it.
Please note that the two structures that burned both had shake shingle (wooden) roofs that ignited from hot sparks.
One might not think many sparks or embers occure hwen burning even in a barrel, but taking a look at a night time picture tells the real story.
