About this map

Porcupine Ridge and the Bear River Range dominate this late-1960s survey of Cache County, Utah. The landscape is defined by the high-elevation terrain of the Cache National Forest, where steep drainages like Blacksmith Fork Canyon and Hyrum Canyon cut through the limestone slopes. At the southern edge of the quadrangle, the Porcupine Reservoir pools behind its dam, fed by the East Fork Little Bear River and Porcupine Creek.

Evidence of human activity is limited to a network of rugged transportation routes, including the Pack Trail and various Jeep Trails that provided access for grazing or forestry. Landmarks such as Cooks Cabin and the Gaging Station near the reservoir indicate the seasonal and resource-management nature of the area's development. The map details numerous smaller drainage systems like Cinnamon Creek and Scare Canyon, illustrating the complex hydrology of this part of the Wasatch Range before modern recreational expansion.
