About this map

Colusa and Adrian anchor this mid-1960s survey of the Illinois prairie, where the landscape transitions from the flat agricultural fields of Rock Creek and Pilot Grove to the dissected stream valleys in the north. The Chicago Burlington and Quincy railroad cuts a straight north-south line through the center of the map, serving as a primary corridor between these rural communities. Near the center of the sheet, the Nauvoo-Colusa Sch marks a point of regional education for the surrounding farmsteads.

Genealogists will find a wealth of family and community history preserved in the numerous small burial grounds, including Tull Cem, Harris Cem, and Pontoosuc Cem. The terrain is defined by a series of drainage systems such as Opossum Creek, Camp Creek, and Grove Creek, which carve deep contours into the otherwise level landscape. The northern portion of the map also details the corporate boundaries of Pontoosuc and Dallas City, illustrating the footprint of these river-adjacent townships during the mid-20th century.
