The Upper Mississippi River National Wildlife and Fish Refuge dominates the western edge of this landscape, where the floodplain transition is marked by complex waterways like Potter Slough and Old Goose Lake. The settlement of Thomson sits just above the marshlands, serving as a hub for the surrounding agricultural uplands. Moving east, the terrain rises into the bluffs along Scenic Bluff Rd, where the drainage patterns of Johnson Creek and Otter Creek have carved a network of ridges and hollows.
