I think the official map underestimates the trail length at 2.2 miles.
This track starts at the parking lot for the Baum Conservation Area. There’s also a parking lot closer to the trailhead on the other side of Goss Road.
Around waypoint A, we came to an obvious intersection and turned right (trying to avoid end up at Dogford Road). However, the trail got less maintained and eventually came to a dead end at B. We went up the hill to the left and were eventually able to find the Mason Trail. In retrospect, perhaps we should have continued past A looking for an intersection that had a sign.
