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