The North Fork Blackfoot River flows through this Powell County landscape, anchored by the heights of Ovando Mountain and McCabe Mountain. In the valley below, the map documents a network of hydraulic engineering essential to the region's ranching heritage, featuring the Jacobsen Ditch, Murphy Ditch, and Krutar Ditch. These waterways support established local holdings such as the Jacobsen Ranch and Murphy Ranch, centered near the settlement of Geary.
