The Canada / United States of America border defines the southern edge of this topographic survey, highlighting the international boundary line north of Pembina Co, North Dakota. The landscape is characterized by the structured grid of the Public Land Survey System and a network of drainage channels that move water across this flat, agrarian terrain. While the sheet primarily documents rural areas in the vicinity of Altona, Manitoba, it provides a precise look at the land divisions and water features as they existed shortly after the mid-2010s. The transition from North Dakota into Canada is marked by subtle shifts in the road and drainage patterns, offering a clear record of the geographic boundary in this borderland region.
