Bullhead sits in the northwest corner of South Dakota's Corson County, part of the Standing Rock Sioux Reservation. Of the 308 residents, 299 (97%) are Native American, making this one of the most homogeneous tribal communities in the state. The median age of 21.5 years signals a young population, with households averaging 4.6 people (typical of extended family structures common in tribal communities).
This is a PO Box Only Zone. There's no alternative mail delivery across the 12.8 square miles. The post office maintains 86 PO Boxes for 67 households, giving a PO Box adoption rate of 1.28. That means more boxes exist than local homes because surrounding areas without mail service also rely on this post office.
Street names tell the story of Lakota heritage. Sitting Bull Avenue (10 delivery records) is the main thoroughfare, followed by Hunkpapa Avenue (7 records) and Rain in the Face Avenue (5 records). Other streets honor Lakota leaders and language: Tasunka Street, Wambli Avenue, Pizpiza Avenue, and Blackhorse Avenue. The community also uses Bureau of Indian Affairs road designations like BIA 21.
Public administration employs 38% of the workforce (38 of 100 workers), which typically means tribal government jobs. The median household income is $32,614, and per capita income is just $7,620. Educational attainment is low, with only 7.8% holding bachelor's degrees. These figures point to economic challenges common in rural reservation communities.
While mail delivery includes both city routes (2 records) and rural routes (34 records), the PO Box Only Zone designation confirms that residents can't receive street delivery. General Delivery is also available, serving those without permanent addresses. The post office works as a gathering point where community members pick up mail, packages, prescriptions, and government documents.
Street names honor Lakota leaders like Sitting Bull and Rain in the Face, with Lakota language words like Tasunka, Wambli, and Pizpiza.
