About this map

Bighorn National Forest dominates this landscape in northern Johnson County, where the transition from high mountain peaks to the western plains is marked by a complex system of early irrigation infrastructure. The map reveals an intricate network of water management features, including the Penrose Ditch, Brown and Foster Ditch, and the Moeller Ditch, which redirect snowmelt from high-altitude sources like French Creek and Clear Creek. These waterworks supported the agricultural development of the region below the North Ridge.

A notable historical marker on this sheet is the Old Military Reservation Boundary, tracing the legacy of frontier defense lines through the high country. Elevations vary significantly from the meadows of Elgin Park to the prominent heights of Grouse Mountain and Bald Ridge. Near the eastern edge, small developed pockets such as Trailer Park and Trail Side appear alongside the winding Johnson Creek, illustrating the intersection of recreation and utility in the late 1960s.
