This curiosity is in Marshall County, about a quarter of a mile from
the Ohio; it is 69 feet high, and 900 feet in circumference at the
base, and has a flat top about 50 feet in diameter.
"A few years since a white oak, of about 70 feet in height, stood on
the summit of the mound, which appeared to die of age. On carefully
cutting the trunk transversely, the number of concentric circles showed
that it was about 500 years old."
