Trail is blocked by a beaver pond. There's a herd path around this, downstream (west) of the dam.

The "center trail" is a well-used dirt road. The north-south trail branch to the SE is unblazed/abandoned; official trail is the SW branch, and it joins the George Washington orange trail around the pond, blazed red and orange.
