Principal facts for gravity stations in and adjacent to the Superstition Mountains, Gila, Pinal, and Maricopa counties, Arizona

A gravity survey was made in the Superstition Mountains in Gila, Pinal, and Maricopa Counties during November 1976 as part of a wilderness study being conducted by the U.S. Geological Survey and the U.S. Bureau of Mines. The purpose of the survey was to map buried structural boundaries and features (e.g. caldera margins) that are important in assessing the mineral potential of the area.
