The Illinois River serves as the dominant geographical and economic boundary in this early 1970s survey, separating the uplands of Timber and Logan from the bottomlands of Spring Lake. The village of Glasford stands as a central hub on the northern plateau, surrounded by the remnants of smaller 19th-century settlements like Lancaster, where the Lancaster East Sch and several family cemeteries remain. Along the river’s edge, the map documents a heavy industrial and extractive landscape, from the Strip Mine and its Tailings Ponds in the west to the Kingston River Terminal near Kingston Mines. The southern portion of the quadrangle is defined by a complex levee system protecting the agricultural tracts and the Spring Lake State Park from the river's seasonal shifts, while the Toledo Peoria and Western railroad provides a critical transportation corridor through the rugged ravines of Copperas Creek.
