About this map

The Cannonball River winds through the northern reaches of this Sioux County landscape, defining the border between Sioux and Grant counties near the settlement of Shields. This 2014 survey documents the open prairie of the Porcupine District, where the terrain is punctuated by significant natural landmarks like Piuss Butte. The area is marked by a grid of rural roads and the prominent Bia-7 route, which serves as a primary artery connecting the various small communities and ranchlands.

Local history and genealogy are anchored by specific markers such as the Congregational Cem and the settlement of Chadwick. The drainage of Porcupine Cr cuts through the eastern half of the map, illustrating the hydrological patterns of the northern plains. This map provides a clear picture of the modern spatial organization of these rural townships, from the sparse residential clusters to the enduring topographic features that have guided navigation and land use for generations.
