MN10 - Mischance Mine - Moongate
Man tried his hand at hiding it, but the low arch in living stone, innocuous, dotted here and there with deep blue growths of azurite and malachite, remains standing.
A natural result of water on the stone, whatever flow carved out this low tunnel must have been changed before it got too far, for its length is barely deep enough to deserve the name 'tunnel' at all, five foot ceiling sloping down toward the four foot arch.
While the arch exists, there's scarcely room for even a child to stand on its far side, and no obvious reason for the fear needed to board the tunnel up.
