Before you go

These open questions need confirmation; Wayproof does not fill them with guesses.

What exact pedestrian connector joins the official Mammoth Pass Trailhead point at Horseshoe Lake to the reviewed McLeod Lake route geometry?

The authoritative trailhead point is now published, but the reviewed source route begins about 55 meters away and no reviewed source provides the short connector geometry. Wayproof does not bridge it by proximity.
