1968 Map of Big Gulch

About this map

Shepperson Ranch sits within a landscape defined by an extensive network of ephemeral waterways in Natrona County, Wyoming. The terrain is marked by the presence of numerous Drill Holes, indicating subsurface exploration and resource management during the mid-to-late 20th century. The drainage patterns are complex, featuring Dugout Creek and Bothwell Draw in the north, while the southern portion is shaped by the South Fork Castle Creek and Alkali Creek. A significant human imprint on the land is the Old Railroad Grade, which traces a path through the central sections of the quadrangle. This feature suggests a legacy of former industrial or transit infrastructure that preceded the late-1960s photogrammetric mapping. The map also records the hydrological divide between systems like the North Fork Dead Horse Creek and the central Big Gulch Creek.
