7.5’ Quadrangle Geologic Maps

Alphabetized List

These maps cover 7.5 minutes of latitude by 7.5 minutes of longitude, or about 55 square miles in Utah, and are the standard series for detailed geologic mapping. In this series, one inch on the map represents 24,000 inches, or 2,000 feet, on the ground.

Maps at other scales cover some of the gaps in Utah coverage: 1×2-degree quadrangle geologic maps, 30’x60′ quadrangle geologic maps
