Keene Member of Horicon Formation is here named for community of Keene in Portage Co. Unit includes brown or reddish brown unbedded noncalcareous and slightly calcareous till of the Arnott moraine deposited by Green Bay Lobe. Consists of 2 to 20 percent gravel, 65 to 85 percent sand, 5 to 25 percent silt, and 8 to 17 percent clay. Underlies and overlies undifferentiated sands of the Horicon Formation though it is presumed to underlie Mapleview Member in the eastern part of the county. Thickness ranges from 10 to 30 m. The Keene may be several times older than the Mapleview and is considered to be pre-Wisconsinan.

Pg. vi (chart), 25-27; see Clayton, Lee, 1986, Wisconsin Geol. Nat. Hist. Survey Inf. Circ., no. 56, 19 p. Keene Member of Horicon Formation. Till. Brown or reddish-brown, unbedded, slightly gravelly to gravelly, sandy loam and loamy sand. Basal 4+/- m is slightly gravelly to gravelly sand. Total thickness typically 10 to 30 m. Is a surface unit limited to type area. Overlies sand of Horicon Formation. Interpreted to be till of an end moraine formed by Green Bay Lobe during the Arnott Glaciation (undated). Age is considered Pleistocene (possibly pre-Wisconsinan or early Wisconsinan), based on degree of weathering and erosion.
