M16.25

Drilled in Season 10, 11 feet south of K15.5. At 103 feet it met a four-foot opening where an underwater camera showed timbers, one with what appeared to be a dowel. Sonar mapped a 35-foot structure trending toward the Garden Shaft.

Positions on the map are approximate; each dot marks the top of the hole.
