1951 Map of Willow Creek NW

About this map

Pine Ridge Indian Reservation lands within Shannon County are defined here by a series of prominent drainage systems and high plateaus. The topography is dominated by the Squaw-Humper Table in the northwest, a distinctive landform that gives rise to Squaw-Humper Creek. The 1951 field survey reveals an area defined by natural boundaries rather than dense human settlement, illustrating the complex hydrology of the region through the branching of Middle Fork Willow Creek, East Fork Willow Creek, and West Fork Willow Creek. These watercourses carve through the terrain, indicating a landscape where seasonal water flow and livestock grazing were primary considerations. The inclusion of 1970s revisions highlights the enduring physical geography of the reservation as it stood in the mid-20th century.
