1985 Map of Miller Coulee West

About this map

Miller Coulee and its surrounding drainage systems define this section of Valley County during the mid-1980s. The landscape is characterized by an extensive network of water management features, including the large Grub Detention Reservoir and specialized catchments such as Itcaina Detention Reservoir and South Beaver Detention Reservoir. These man-made improvements speak to the careful regulation of seasonal runoff across the high plains. Natural watercourses like Sage Hen Creek and Little Beaver Creek thread through the terrain, punctuated by family-named or descriptively titled landmarks like Arrambide Coulee and Lonely Night Reservoir. This survey provides a precise look at the ranching infrastructure and hydrological adaptations required for life in this part of Montana just before the turn of the millennium.
