The cross is not aligned with north and south. The cross should be corrected to align with magnetic north and reflected to the east. The intermediate stone on the long shaft marks where the money pit shaft is the money pit can then be found by exploring the 10 % calculation.
I believe the cross is a surveying tool to draw out the flood tunnel orientation and i believe the swamp may be a sump system connected to them, the eye in the swamp also lines up perfectly possibly suggesting a drain formation feeding into the tunnels
