USGS Topo · Published 2017About this map
The Missouri River creates a prominent bend through this part of Cascade County, shaping the local geography around Nelson Island and the small riverside community of Riverdale. This 2017 survey illustrates a landscape of high coulees and river bottoms, where historical road networks like Old Ulm Cascade Rd and Old US Hwy 91 track the movement of people and commerce between the settlements of Ulm and the valley below.
