About this map

This remote northern frontier in Blaine County, Montana, is defined by its position along the international border with Canada. The landscape is a complex network of seasonal drainage channels and small, scattered wetlands typical of the high plains north of the Milk River. Mapping from the U.S. Geological Survey and the U.S. Census Bureau illustrates a region where natural water distribution and the vast boundary line are the primary geographic features. The lack of named roads or established settlements on this specific sheet emphasizes the open, agricultural, or grazing nature of the land at the edge of the United States. This survey provides a precise look at the topography and natural drainage patterns of the Montana prairie just before it crosses into Canadian territory.
