About this map

Mermet Lake and its surrounding wetlands anchor the southwestern corner of this landscape, where the boundary between Johnson Co and Massac Co divides a region defined by complex drainage networks. The southern lowlands are heavily managed by a system of man-made waterways, including the New Columbia Ditch, Bear Creek Ditch, and Main Ditch, which redirect water through former marshlands toward the Ohio River basin. In contrast, the northern terrain rises toward distinctive elevations like Blue Knob and Cagle Bluff.

Family history is deeply etched into the topography through numerous small burial grounds and crossroads settlements. Small communities like New Columbia, Ganntown, and Samoth serve as local hubs, while specialized sites such as Masonic Cem Number 10 and Nineveh Cem offer specific touchpoints for genealogical research. The map captures a rural Illinois landscape where modern interstate travel bisects traditional farm-to-market routes like Old Metropolis Rd.
