About this map

North Sterling Reservoir (Point of Rocks Reservoir) dominates this Logan County landscape, serving as a critical water management feature for the region's agricultural economy. Fed and drained by a complex network including the North Sterling Canal and the North Sterling Outlet, the reservoir's irregular shoreline is punctuated by a massive Spillway and nearby Rodeo Ground. This late 1970s survey illustrates a rural environment where water security and resource extraction coexist, with numerous Oil Wells and a distinct Pipeline cutting across the terrain.

Erosional features and ephemeral water sources define the surrounding high plains, from the prominent Flattop Butte to the drainages of Beall Creek and Darby Creek. Named water sources like Seventenmile Spring and Blood Spring highlight the importance of localized groundwater in an area marked by rugged breaks and dry draws. The map also records early local infrastructure, including a Drill Hole and multiple locations simply labeled Well, indicating the ongoing search for subsurface resources.
