1968 Map of Duck Lake

About this map

The high plains and headwaters within the Blackfeet Indian Reservation dominate this landscape, where the northern waters of Duck Lake meet a series of prominent topographic rises. The terrain is defined by the sharp ascent of Saint Mary Ridge and a local Divide, which direct the flow of numerous waterways. Significant hydrological features include the Middle Fork Milk River and the Dry Fork Milk River, which carve through the undulating landscape alongside Livermore Creek. This late-1960s survey provides a clear view of the open range and essential water sources, such as a mapped Spring, that sustained life on the reservation during this era.
