1969 Map of Porcupine Reservoir

USGS Topo · Published 1973

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.
