I was looking through some photos taken in March of the prescribed fire along the Fall River in Hot Springs, South Dakota. The flames in this picture got my attention — small chunks of flames continue to exist several feet from the main body of the flames. The photo was taken at a fairly fast shutter speed, 1/500 second.

Click on the photo to see a larger version. I manipulated the colors a bit to make the flames show up more clearly.

Below is a video shot at the project.
