Pg. 18, 55, 57, 84, 85, 101. Parkland facies (informal) in Henry Formation of Mason Group; Parkland facies (informal) in Peoria Silt of Mason Group. Well sorted, medium- to fine-grained sand. Represents reworked eolian facies of the Henry; commonly occurs above glacial and postglacial fluvial and lacustrine sand and gravel of the Henry. Where it interfingers with the Peoria Silt, it may be more appropriately classified as Parkland facies (informal) in Peoria Silt. (Formerly Parkland Sand of Willman and Frye.) Age is Pleistocene (Wisconsinan Age; Woodfordian Subage), based on radiocarbon dating, and part is considered Holocene.
