2019 Map of Marine on St. Croix

About this map

Marine on St. Croix and the surrounding Washington County landscape are defined by a complex network of glacial lakes and the steep valley of the St. Croix River. The settlement patterns in this area show a clear division between the riverfront heritage of Copas and Otisville and the agricultural upland around Scandia. Transportation infrastructure is dominated by the Minnesota Wisconsin railroad line following the river's edge, while the interior is marked by numerous water bodies including Big Marine Lake, Square Lake, and Big Carnelian Lake. Local history is preserved at sites like Elim Cem and Oakland Cem, which serve as anchors for genealogists. The eastern boundary is shaped by the St. Croix Wild and Scenic River, where the state line meets Greenburg Island. In the south, the presence of Keller Airport signifies the area's continued role as a gateway between the Twin Cities and the river valley.
