1994 Map of St. Helena

Local history is preserved in the location of the St Helena Cem and Trinity Cem, while the agrarian and industrial roots of the region are noted at Bow Valley Mills. The map also highlights conservation efforts with the State Game Production Area near the riverbanks. This document captures the intersection of three counties—Cedar, Yankton, and Clay—along a complex riparian border where shifting sands and man-made features like Clay Ditch reveal the long history of land use and water management.
