Geologic map of the Porcupine Reservoir quadrangle, Cache County, Utah (M-113)

By: L. Berry

The Porcupine Reservoir quadrangle area is in the southern Bear River Range of northern Utah approximately 4 miles east of the town of Paradise. The Bear River Range is included in the Middle Rocky Mountain physiographic province. Maximum relief in the area is about 3300 feet; altitudes range up to 8529 feet near the head of Miles Canyon. Blacksmith Fork Canyon, in the northern part of the Porcupine Reservoir quadrangle, is known for its complete and well-exposed Paleozoic section and has been a mecca for stratigraphers for over 100 years. Geologic maps of the area are outdated and ofsmall scale, therefore an updated map and better delineation of Paleozoic stratigraphy and structure of the Porcupine Reservoir quadrangle are the emphasis of this study.
