The White River carves a deep, meandering path through the Lyman County landscape, defining the southern portion of this mid-century survey. The agricultural and rural character of the era is evidenced by a network of one-room schoolhouses, including North Cooper Sch, West Cooper Sch, and East Cooper Sch, which served the outlying farmstead families. In the north, the Chicago Milwaukee St Paul and Pacific railroad parallels the American Crow Creek, providing a vital transit link near the Reliance city boundary. One of the most significant historical details captured here is the planned submergence by the Fort Randall Reservoir, with broken blue lines marking the land destined to be underwater, particularly affecting the areas near the riverbanks and the Black Dog area.
