Salmon Hole is known to be highly populated with beavers and my last visit confirmed this for me!
As I traveled a little further down the river from my phenology spot, I noticed the beginning of a dam being formed by the waters edge. Drift wood was floating away from the structure which made me believe that there was recent movement around the area. The signs did not stop here; Almost every tree that was medium sized in diameter had evidence of beaver behavior on it. Whether the tree was half chewed, scratched, or fully chewed down, there was definitely a beaver in the area recently.
