Write a detailed description of a spooky scene outside of a wilderness stream with a bridge, creek, trunk, and a tree.

The dark, tannic water of the reed-choked creek moves just enough to keep it from becoming completely stagnant. The ribs of a collapsed bridge jut out of the scummy water. The creek banks are steep and slippery. Overhead, just out of reach, the denuded trunk of a tree spans the creek. To the south the creek becomes an impassable slough.
