1963 Map of Breed Spring

About this map

Flatwillow Creek meanders through this landscape in Petroleum County, defining the drainage patterns of the central territory. Surveyed in the early 1960s, the map reveals a remote section of Montana where life revolved around scarce water sources like Breed Spring. The terrain is marked by deep coulees, including Gorman Coulee in the north and Anderson Coulee to the south, which serve as natural landmarks across the open range. In the northwest corner, Box Elder Creek cuts through the high ground, while the southern boundary is shaped by the headwaters of North Maginnis Creek. This survey captures the rural character of the Big Sky Country before significant modern development, documenting the specific locations of named springs and seasonal waterways essential for ranching and land management in the mid-twentieth century.
