Principal facts for gravity stations of part of the Selway-Bitterroot Wilderness, Idaho and Montana

During the summers of 1978 and 1979, 211 gravity stations were established in the Selway-Bitterroot Wilderness area (Fig. 1). The data were obtained as part of the U.S. Geological Survey's (USGS) program to evaluate the mineral-resource potential of wilderness areas. This gravity survey complements a gravity study of the proposed Blue Joint, Magruder and Meadow Creek wilderness study areas (Bankey and others, 1980).
