Somonauk and Sandwich anchor this agricultural landscape along the county line between De Kalb and La Salle Counties. The region is defined by the course of Somonauk Creek, which winds through the central townships of Victor, Somonauk, and Sandwich. In the early 1970s, the emergence of residential water-oriented communities is evident at Lake Holiday, contrasting with the established agrarian grid of roads like Suydam Road and Chicago Road.
