1967 Map of Slim Butte NW

About this map

Swallow Ch stands as a focal point for the rural landscape of Shannon County during the late 1960s, situated amidst the complex drainage systems of the Missouri River Basin. The terrain is defined by the carved paths of Blacktail Creek and its tributary, the South Branch Blacktail Creek, which wind through the northern sections of the quadrangle. To the south, Slim Butte Creek marks the transition toward the eponymous butte formations. This map, field-checked in 1967, documents a sparsely populated ranching or tribal land environment where infrastructure is limited to light-duty and unimproved dirt roads. The placement of the church and the naming of these specific waterways provide essential landmarks for genealogists and local historians tracing family holdings or community centers in this portion of South Dakota before later administrative changes renamed the county.
