2015 Map of Astoria

About this map

The town of Astoria sits atop the Coteau des Prairies, a vast plateau that shapes the geography of eastern South Dakota. This 2015 survey reveals a landscape defined by the traditional grid of the Public Land Survey System, where sections are clearly marked by gravel roads and section lines like 482nd Ave and 195th St. Water is a defining feature of the local terrain, appearing in the form of glacial depressions and drainages such as Cobb Cr and Oak Lake. For genealogists and local historians, the map identifies specific community landmarks including Bethany Cem and Bethlehem Cem, alongside geological features like Jorstad Spring. The boundary between Deuel County and Brookings County crosses the southern portion of the sheet, illustrating how these political divisions overlay the natural contours of the high prairie.
