Mapleview Member of Horicon Formation. Following the informal usage of McCartney and Mickelson (1982), the Mapleview Member of the Horicon Formation (new name) is here named. Lies on the west side of the Green Bay Lobe in Langlade and Marathon Counties, Wis. Consists of brown to reddish-brown, cobbly, pebbly, silty sand till. Overlies sand and gravel; interfingers with or sharply underlies the Nashville Member (new name) of the Copper Falls Formation (new name) or lies at the surface. Correlates with the Liberty Grove Member (new name) of the Horicon on the east side of the Green Bay Lobe. Thickness is unknown. Age is Pleistocene (late Wisconsinan).
