2018 Map of Porcupine

About this map

The Cannonball River defines the northwestern corner of this landscape, marking the boundary between Grant and Sioux counties. The settlement of Porcupine serves as a central hub, where BIA Rte 7 and BIA Rd 7 converge near several local landmarks. This area is characterized by scattered rural communities and high points like Pluss Butte. Local history and genealogy researchers will find significant detail in the cluster of sacred sites near the town center, including the Saint James Catholic Church Cem and the Congregational Cem. To the southeast, the terrain transitions toward Chadwick, while Porcupine Cr meanders through the eastern portion of the quadrangle. The map captures the organized rural layout of the Porcupine District, showing the precise placement of dwellings and the network of section roads such as 34th Ave and 35th Ave that connect these remote homesteads.
