1967 Map of Ft. George Butte SW

About this map

The Old Indian Treaty Boundary cuts through this portion of Lyman County, serving as a significant historical marker in the central South Dakota landscape. Surveyed in the mid-1960s, the terrain is defined by the drainage patterns of several seasonal watercourses, including the South Branch Cedar Creek in the north and the winding path of Nail Creek in the southeast. Large tracts of land are identified by names such as Mcclure, Tracy, and Lund, reflecting the regional landholding patterns of the era. The presence of Knudson Dam and various fence lines, captured through photogrammetric methods, highlights the agricultural infrastructure supporting local ranching operations. The confluence of Stony Butte Creek near the western edge illustrates the remote, watershed-focused nature of the geography during this period.
