1969 Map of Gails Coulee

About this map

Gails Coulee and the surrounding drainage basins of south-central Montana are defined by a network of intermittent streams and natural water sources. In the late 1960s, this landscape straddling the Yellowstone Co Big Horn Co line remained largely undeveloped, characterized by the winding paths of Tenmile Creek and Barley Coulee. A notable human addition to the terrain is the Landing Strip located north of the Base Line, indicating the importance of small-scale aviation for reaching this area of the high plains. The map also captures the local hydrography through features like Alkali Spring and Hay Creek, reflecting the importance of water management in a region where reliable springs were critical for livestock and land use. The southern portion of the sheet is bisected by a major highway corridor, featuring a designated Rest Area near the county boundary.
