I remember something about a huge crystal having been sighted(?) in the area from years ago... Pretty fuzzy memory on it, but seems like someone was studying anomalous energy readings at the time.

Looks like it will require some digging around in the "wayback machine" or the deep web to find it though (hopefully it is still archived).

No time at the moment to do this, but I think a search on Bimini crystal might get some hits, if anyone wants to give it a shot. Otherwise, I will try to remember to do it later today.
