"About a mile southward of Hazen Corners . . . is a group. . . . They are all situated on the northern slope of the ridge not far from the top."[1]

“Some 10 or 12 miles southwest of the battle-field of Belmont [Missouri] is one of the peculiar sand ridges of this swampy region, called Pin Hook ridge. This extends 5 or 6 miles north and south, and is less than a mile in width. . . There is abundant evidence here that the entire ridge was long inhabited by a somewhat agricultural people, with stationary houses, who constructed numerous and high mounds, which are now the only place of refuge for the present inhabitants and their stock from the frequent overflows of the Mississippi."[3]
