Here in southern ohio there were all sorts of old indian legends about giants. They would steal the women and eat the kids, or something like that.

Indians burnt down entire forest's killing them, supposedly.

Anyway again supposedly they dug up skeletons, lots of them in the 1800's when clearing the local indian lands for farming. Alot of sites and artifacts were destroyed.

The claim is that the bones turned to dust shortly after being dug up.

Kinda sounds like bullshit, I know. Then I came across a story about a hermit who lived in this part of southern ohio.

Really interesting story on its own, but the part to note here.

Dear Sir - All the bones of Hewitt , the hermit, that I now have in my possession are the three bones of the right arm, humerus, radius, ulna, and the entire skull without the lower jaw. The skull has been sawed in two just above the brows. The bones sent to me by Mr. Emmitt were crumbling when received from him, and continued to do so till they were in powder. The other bones that I now have a perfect, solid and well preserved. Five teeth and a piece of one remain in the upper jaw, none of them showing signs of decay. One has a large cavity, which has never been filled. The skull is of good size, of symmetrical shape, and is thicker and heavier than the average. It shows, with the teeth, that it belonged to a strong man, past the prime of life.

Something in the soil there that just eats something mineral in the bone itself is my guess.

Makes me wonder about these old indian legends, legends which dont seem to exist except out of oral tradition anymore. Makes me awfully curious.
