1970 Map of Piyas Lake

About this map

Piyas Lake and the surrounding glacial prairie of the Coteau des Prairies dominate this landscape at the intersection of Marshall and Day counties. The 1970 survey captures a region defined by its water and conservation efforts, featuring the National Wildlife Management Area and the recreational development at Pickerel Lake State Park. Social and spiritual centers of the rural community are anchored by the Buffalo Lake Ch, an isolated Cem, and a Church Camp situated on the southern shores of Pickerel Lake. The map details the complex boundaries of local townships including Eden, Nutley, Kosciusko, and Grenville, while also noting the Indian Reservation Boundary that bisects the northern sections. This topographic study preserves the mid-century layout of section roads and small-scale resource extraction like the Gravel Pit near the lakeshore.
