Coming from the west, this trail is not passable. I tried for some time the other day while on a long run and eventually gave up. It's unmaintained, bushy, and, well, I couldn't even find the trail beyond this point. I wound up going east cross country (it's grass), and eventually found another point further down where I could cross with only a modicum of danger.

Anyway, I think the map needs to be updated to remove this path past this point, but I don't know how far you can go on this path when coming from the east.
