About this map

The Missouri River carves the northern boundary of this landscape, marking the border between Roosevelt County and Richland County. The terrain is defined by a dense network of coulees and bluffs, including the distinctively named Promised Land Coulee and Balls Bluff. This area, primarily characterized by open ranchland and high plains drainage, is segmented by numerous seasonal watercourses such as Charlie Creek, which splits into several named branches including West Charlie Creek and East Charlie Creek.

Evidence of local heritage and the rural community structure is centered around historic sites like Saint Bernards Church Cem and Lynd Cem. These points of interest, connected by a grid of county roads such as Co RD 321, provide essential landmarks for genealogists tracing family roots in this corner of Montana. The map illustrates a high-desert environment where names like Wolf Coulee and Big Basin Coulee reflect the early settlers' descriptive navigation of the complex topography.
