2017 Map of Gails Coulee

About this map

Gails Coulee and the surrounding drainage networks define this high-plains landscape along the border of Yellowstone and Big Horn Counties. The terrain is deeply inscribed by seasonal watercourses, including Tenmile Cr in the north and the meandering Alkali Cr to the south. This 2017 survey illustrates a modern rural infrastructure where established ranch roads like Indian Creek Rd and Milam Rd navigate the township and range grid. The presence of Barley Coulee suggests the agricultural importance of these natural depressions for water management and land use. This map serves as a clear record of the watershed patterns and transportation corridors, such as E Arrow Creek Rd, that support the region's ranching economy.
