In addition to Jimerson Town, significant developed communities on the reservation include: Highbanks, a community south of Steamburg that includes residences, smoke shops, a Faithkeepers School and a campground; Shongo, a sparsely populated hamlet south of Jimerson Town; Kill Buck, a mixed community of both native and non-native residents; The Junction, a mostly commercial cluster surrounding an exit on Interstate 86; and Vandalia, the easternmost developed site on the reservation. South of Highbanks, the reservation is primarily undeveloped wilderness. Wilderness is also the predominant form between Steamburg and Shongo, where natives often take part in hunting and informal recreation. Each area is also given a name in the Seneca language: the Coldspring-Steamburg area is known as jonegano:h, Shongo and Red House are known as joë:hesta' , Salamanca is dubbed onë:dagö:h, while everything from Kill Buck eastward is named dejódiha:ˀkdö:h. These names appear on markers on Interstate 86.
