1981 Map of Coleharbor NE

About this map

Greatstone and the surrounding plains of McLean County are defined by a complex landscape of wetlands and water management systems in the early 1980s. The map captures the significant ecological footprint of the Audubon State Wildlife Management Area and the Lake Nettie National Wildlife Refuge, reflecting a region dedicated to conservation and waterfowl habitat. The northern reaches of Audubon Lake dominate the southwestern corner, while Snake Creek meanders through the western section. Local social and religious life is anchored at the Greatstone Ch and the Greatstone Community Cem. The presence of both a Townhall and a separate Community Hall indicates a dispersed but organized rural population. Scattered gravel pits and fencelines reveal the intersection of local industry and agriculture within this protected prairie pothole region.
