This may be a dumb question, but has anybody dug up the area around the cross? Maybe there is something else there.
As far as I know there has been no digging around the cross. Hopefully, TES at least checked the area with their locating equipment.
There was digging reported at the fishermen's huts early on, and at the shallow "grave" hole found on the east side.
That's a good question, because I recall it being stated that the ground around the Fishermen's Huts was like sinking sand. As you try to dig, it fills in right behind you and you just keep sinking. Whoever placed that cross there KNOWS something and has a guilty conscience. They are attempting to send a message without revealing themselves.
