Large fossilized human remains found in Ohio. Article from Nov. 17, 1869

The article says that the body was 10 ft. 2 in. (3 m. 10cm) long from head to toe, and still had rotting flesh on it. It was found at a depth of 2.5 feet, or 76.2 cm, when someone was trying to dig a well. There have been many such finds in Ohio, largely attributed to the "Adena" culture, who left behind many mounds and structures.
