“The next group surveyed ... are on the crest of the ridge heretofore mentioned and on both sides of the Black River Road.”[17]
“Mound No. 23 ... is also in the form of a bird with outstretched wings. It lies ... on top of the ridge, with the head lying crosswise of the highest point.”[18]
“Mound No. 24 is close to the right or east, on the high part of the ridge, extending in the same direction as 23.”[19]
“Northward of this group some 400 yards, there is a mound in the form of a quadruped, probably a fox, ... partly in the woods and partly in the field on the west side of the road. It is built on the crest of the ridge with the head to the south.”[20]
“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.”[21]
“... A small group ... situated west of the Black River Road, ... on the top of the ridge in the woods. The ridge slopes from them to the east and west.”[22]
“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.”[23]
“These ... are situated on the county road from Cairo, Illinois.... They are the highest ground in that immediate section” (Missouri).[24]
