2011 Map of Porcupine Reservoir

About this map

Porcupine Reservoir anchors the southwestern corner of this drainage basin, where the Porcupine Dam regulates the waters of the East Fork Little Bear River. The landscape is defined by its deep canyons and hydraulic network, including the prominent Blacksmith Fork running across the northern reaches and the winding Cinnamon Creek to the south. Historically significant landmarks like Cooks Cabin and named high-altitude areas such as Bear Flat reflect the area's long-standing use for ranching and seasonal habitation.
