1972 Map of Frog Coulee

About this map

The Missouri River defines the northern boundary of this landscape, separating the rugged drainage basins of the south from the Fort Peck Indian Reservation to the north. In the early 1970s, this portion of Richland County was characterized by a complex network of coulees and creek beds that carved into the high plains. Vital community landmarks like St Bernards Ch and Lynn Cem are situated on the upland reaches, serving as focal points for the dispersed homesteads and farms of the era. The naming of Land Promised Coulee and Frog Coulee suggests the varied character of the local geography as it descends toward the Missouri. This survey captures a moment when the land was precisely divided by county lines, with the Roosevelt and Richland border cutting through the river's channel.
