1950 Map of Sumner

The geography is dominated by water and conservation efforts, with the northern reaches occupied by Pershing State Park along Locust Creek. To the south, the vast Swan Lake National Wildlife Refuge borders Swan Lake and Silver Lake. Between these protected areas, the map records a high density of one-room schoolhouses and family-named cemeteries, such as Prairie Mound Sch, Taylor Sch, and Taylor Cem, reflecting a well-established farming community connected by a series of levees and winding waterways like Turkey Creek.
