1983 Map of Thompson Lake

About this map

Thompson Lake serves as a central landmark in this drainage-heavy landscape of western South Dakota, where the intricate network of the Cheyenne River watershed is clearly defined. The terrain is characterized by the winding paths of Cherry Creek in the north and Red Owl Creek through the center, illustrating the erosional patterns of the northern plains. This provisional study, based on 1970s aerial photography and early 1980s field checks, reveals a landscape primarily dedicated to ranching and open range, evidenced by features like Cowboy Draw.
