2023 Map of Porcupine Reservoir

About this map

Porcupine Reservoir anchors the southwestern corner of this high-elevation landscape, where the East Fork Little Bear River meets the drainages of Porcupine Creek and Beaver Creek. Situated within the Cache National Forest, the terrain is defined by the steep rises of the Bear River Range and prominent landmarks like Mineral Point and Porcupine Ridge. The map documents a complex system of hydraulic geography, from the northern flow of the Blacksmith Fork through Blacksmith Fork Canyon to the deep incisions of Devils Gate Canyon and South Cottonwood Canyon. The absence of large-scale settlements highlights the area's character as a managed wilderness and watershed, marked by natural flats such as Bear Flat and winding canyon systems like Scare Canyon and Hyrum Canyon.
