About this map

Fort Belknap Indian Reservation Boundary defines the eastern portion of this landscape in Blaine County, Montana. This 1971 field-checked survey reveals a rugged, drainage-carved terrain where water sources are vital to the local geography. Central to the map is Putnam Lake, fed by the meandering course of Suction Creek. To the north, the land is etched by Saint Johns Coulee and Fogarty Coulee, illustrating the characteristic erosional patterns of the northern plains.

Elevated landmarks like Haystack Butte and Putnam Ridge provide significant navigational points for researchers tracing historical land use or grazing patterns. The inclusion of isolated features such as a Well and a perennial Spring further underscores the importance of water management in this cattle-ranching region. These specific terrain and water labels offer a detailed look at the Missouri River Basin's development during the early 1970s.
