2017 Map of Porcupine Reservoir

About this map

Porcupine Reservoir anchors the southwestern corner of this landscape, where the waters of Porcupine Cr and the E Fork Little Bear River converge. The terrain is defined by a dense network of drainages and high ridges within the Cache National Forest, showing a complex system of canyons that shape the local geography. Significant elevation changes are marked by features like Porcupine Ridge and Mineral Point in the south, while the northern reaches are carved by Devils Gate Canyon and the Blacksmith Fork river. This 2017 survey illustrates the intricate natural drainage patterns of Cache County, where smaller seasonal streams such as Hyrum Cr and Cinnamon Cr feed into the larger river systems. The map details a largely undeveloped mountain environment, highlighting named landmarks such as Bear Flat and Paradise Dry Canyon that serve as vital reference points for local navigation and land management.
