Paul Filmer took some excellent photos of aircraft working on the Fern Lake Fire in Rocky Mountain National Park west of Estes Park, Colorado, December 4, 2012. The photo above is the first one I can remember seeing of an air tanker dropping with snow in the background.
We thank Paul for allowing us to use his photos. You can see a couple of dozen more that photos he took December 4 at his web site. More information about the Fern Lake Fire can be found at Wildfire Today.
