1984 Map of Johnson Dam

About this map

Beaver Creek meanders through the heart of this North-Central Montana landscape, defining a complex network of drainages that characterize the area's hydrology in the late 1970s. The terrain is marked by numerous dry washes and seasonal watercourses, including the descriptive Pickhandle Coulee and Windmill Coulee, which cut through the open country. The presence of a Landing Strip and a solitary Grain Bin in this expansive environment reflects the specialized infrastructure required for remote ranching and agricultural operations. This 1984 provisional edition, based on 1978 field data, centers on the eponymous Johnson Dam, a vital water management feature for the region's livestock-driven economy. The intricate contour lines illustrate the sharp transitions between the level creek bottoms and the higher plateaus that divide Sevenmile Creek from the surrounding coulees.
