1915 Map of Tule Valley

About this map

Fort Peck Indian Reservation dominates this 1915 landscape, surveyed by the General Land Office just before the first World War. The terrain is defined by the broad drainage of the Tule Valley, where the intermittent flow of Tule Creek and its North Fork carve through the plains. The map reflects a period of transition for this part of Montana, showing the early township and range grid system overlaid across the ancestral lands of the Assiniboine and Sioux. Water is the primary marker of life and geography here, from the isolated Spring in the north to the path of Boxelder Creek winding along the eastern boundary. The sparse settlement pattern and lack of major road infrastructure during the 1909-1910 survey period highlight the area's isolation prior to later development.
