History of Fremont County, Iowa 1881
In 1875 a huge Sioux skeleton was unearthed at a brickyard about one mile east of Hamburg at a depth of fourteen feet from the surface of the earth. The bones were for the most part in an advanced state of decay but the teeth were well preserved. The remains are believed to be those of a giant at least eight feet in height. The teeth were worn down almost to the jaw-bone, which fact indicated that the "mighty men of renown" must have lived in the days mentioned by the old Sioux Indians who formerly lived in the vicinity of Hamburg.
