|The artist is "Remus", custodian of The Woodpile Report.|
If that is true, then you can accurately deduce the species of the tree that fell across the creek. You can also guess the age and the habitat (i.e., trees per acre and exposure). That is a tribute to Remus's virtuosity as an artist.
It should also be a cautionary note for just how much information that gets embedded in even the most casual of photographs. That information is just sitting out there for any observant person to extract.
