Summary:

Glasford Formation in Effingham Co., IL, is divided into (ascending) Smithboro Till Member, Mulberry Grove Member, Fort Russell till facies of the Vandalia Till Member, and the Berry Clay Member. The Fort Russell has lithic parameters intermediate to that of the Smithboro and Vandalia Till Members. 23 ft of the Fort Russell till have been described by Kettles (1980) just west of the study area. This facies of the Vandalia is probably the dominant, uppermost Glasford till unit underlying most of Bishop Township.
