Gravity survey in the eastern Snake River Plain, Idaho — A progress report
Thomas R. LaFehr
1961, Open-File Report 62-74
A regional gravity survey in the eastern Snake River Plain was conducted in the early summer of 1961. Seven hundred and seven gravity stations were established between latitudes 42°15'N and 44°30'N between longitudes 111°30'W and 114°30'W. Three hundred and twenty-five of these stations were located in 2,700 square miles of...
