Pg. vi (chart), 49-52. Wildcat Lake Member of the Copper Falls Formation. (Follows informal usage of Attig and others, 1985, GSA Bull., v. 96, 1585-1593; Attig, 1985, Wisconsin Geol. Nat. Hist. Survey Inf. Circ., no. 50; Attig, 1984, Univ. Wisconsin PhD dissert.) Till, and associated debris flow and stream sediment. Till described as reddish brown, uniform, compact, slightly gravelly loamy sand to sandy loam. Pebble fabric strongly developed; long axes lie parallel to ice flow and plunges upglacier. Thickness in subsurface up to 6 m. Underlies debris flow and stream sediment [of Wildcat Lake] with sharp contact. Overlies gravelly sand; contact is abrupt. Equivalent to informal Bass Lake till of Nelson (Univ. Wisconsin MS thesis, 1973). Interpreted as having been deposited by advance of southwest-flowing Wisconsin Valley Lobe (Ontonagon Lobe). Probably nearly age-equivalent of Nashville Member of Copper Falls Formation in Langlade Lobe area. Age is considered Pleistocene (late Wisconsinan).
