1970 Map of Richmond SW

About this map

Richmond Lake anchors the eastern edge of this 1970 South Dakota landscape, where the prairie begins its transition toward the James River valley. The geography is defined by a series of low-lying townships, including Ravina, Carlisle, Cortlandt, and Mercier, which span the border of Brown and Edmunds counties. The map captures a moment when the regional infrastructure was shifting, evidenced by the prominent Old Railroad Grade cutting diagonally through the northern sections, marking a legacy of early steam-era transport that once linked these isolated townships.
