I have to admit that I enjoy that Curse of Oak Island show, which (along with "Ancient Aliens") is the ultimate expression of the open-ended mystery genre. Some kids 200 years ago noticed an old old tree branch looked like it used to have a block and tackle attached to it, and there was a slight concavity in the ground. Since that time, despite the march of technology, no one has been able to thwart the methods used to hide an uniidentified and quite purported treasure using block and tackle and an old oak tree.
I liked the Geologist’s approach. Bulldoze the crap out of it until you find something. However, that approach means you are only treasure hunting. At least the brothers are giving the appearance of archeological interest.
