1968 Map of Rimrock Ranch

About this map

The Blackfeet Indian Reservation landscape is defined by the carved drainages of the northern Montana plains as they appeared in the late 1960s. The terrain is dominated by several significant coulees, including Little Rock Coulee, Powell Coulee, and Cobell Coulee, which create a complex network of seasonal watercourses across the high prairie. The named features reflect a ranching and energy-based economy, notably centered around the Rimrock Ranch and a high-pressure Pipeline corridor that traverses the central and eastern portions of the quadrangle. Numerous unidentified Spring and Springs locations are scattered throughout the draws, indicating vital water sources in this semi-arid region near Harwood. This 1968 field-checked survey provides a meticulous record of the natural topography and the sparse human infrastructure within the reservation boundary.
