K15.5

Drilled by the team in Season 10 in the Money Pit area. Cores at 103.5 and 111 feet held wood, including part of a beam, and the drill dropped at 103 feet into what Terry Deveau read as a structure about five feet tall. The wood was carbon dated with the most likely range 1731 to 1806, and the hole was later resampled for water testing.

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