Yes, thats a slash pile from each tree. The actual loggers in the area push the slash piles into one huge pile rather than just leave it where it lay. There are stumps left behind as well, but that is the law to leave it around 12" high in certain areas.
Another thing I'd like to point out. Notice the tiny little trees or bushes in the original pic? they are gone as well, even logs that i used last year for pictures, gone.
