1972 Map of Spearville

A notable historical marker crosses the southern portion of the sheet: the Old Indian Treaty Boundary, which provides a tangible connection to the region's 19th-century land divisions. The map also records essential community sites for genealogists, such as St Johns Cem, Silent Land Cem, and a third unnamed Cem located near the banks of Coon Creek. These features, along with Hains Lake and several substations, document the rural infrastructure of the early 1970s before mid-1980s updates.
