1919 Map of Boundary

About this map

The International Boundary between the United States and Canada defines the northern edge of this northern Montana landscape, where drainage patterns dictate the placement of early ranching and agricultural outposts. Surveyed by the Corps of Engineers, U.S. Army under Col. Chas. L. Potter, the sheet captures the remote character of Valley County through isolated settlements like Morgan, Tango, and Tobison. The hydrology is dominated by north-south flowing watercourses including Rock Creek, Willow Creek, and Porcupine Creek, which carved the terrain long before modern infrastructure arrived. High points such as Rabbit and Cone provide the only significant elevation markers in an otherwise open prairie environment. This advance sheet serves as a primary source for understanding the early 20th-century distribution of rural centers like Wendell and Midway along these vital creek beds.
