Description: Wyoming aeromagnetic and gravity maps:  Complete Bouguer gravity anomaly (WY only) The complete-Bouguer gravity anomaly grid was compiled using data from over 23622 gravity stations in and adjacent to the state of Wyoming. These data were extracted from the gravity data base maintained by the National Geophysical Data Center (from Department of Defense unclassified data) (Hittleman and others, 1994) and augmented with data from the USGS and from several university theses and dissertations. Isostatic residual gravity anomaly (WY only) The colors on this isostatic gravity map reflect variations in the Earth's gravity field caused primarily by lateral variations in density in the rocks that make up the upper part of the Earth's crust. An isostatic gravity grid was derived from Bouguer and free-air gravity anomaly data. This grid was created by removing from the Bouguer gravity grid a model of the gravity expression caused by deficiencies in mass (compensating mass) that supports topographic loads. Total-field Magnetic anomaly (WY only) Wyoming Merged Aeromagnetic Anomaly Map (NE illumination). The Wyoming aeromagnetic map is constructed from grids that combine information collected in 27 separate aeromagnetic surveys conducted between 1950 and 1997.  Suggested Citation: Kucks, R., and Hill, P.L., 2000, Wyoming aeromagnetic and gravity maps and data: A web site for distribution of data: U.S. Geological Survey Open-File Report 2000-198, HTML Document, https://doi.org/10.3133/ofr00198.
