Stratigraphic relationships[edit | edit source]

The Kenwood Member of the Wapsipinicon Limestone overlies the Otis Member. As originally defined, the Kenwood included strata later differentiated as the Spring Grove Member (Stainbrook, 1935).

Extent and thickness[edit | edit source]

The Kenwood is 15-20 feet thick in the outcrop area. It is 10 feet thick where exposed at the base of a quarry half a mile southeast of Milan, Rock Island County (NW 25, 17N-2W), and 16 feet in the quarry on the south side of Rock Island, Rock Island County (SE 14, 17N-2W), but the base is not exposed in either quarry.

Lithology[edit | edit source]

The Kenwood consists of laminated or thin-bedded, argillaceous, dolomitic limestone with strongly brecciated beds and pockets of clay.
