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.&quot;<\/font><\/li>     <\/ul>     <li><a href='https://pubs.usgs.gov/of/2000/ofr-00-0198/html/wy_iso.htm' target='_blank'><font size='3'>Isostatic Gravity Anomaly Map<\/font><\/a><\/li>     <ul>         <li><font size='3'>&quot;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.&quot;<\/font><\/li><\/ul><ul>     <\/ul> <\/ul><font size='3'><b><div><span style='font-weight:400;'>Data downloaded from USGS have in some cases been minimally modified (e.g., clipped to spatial extent, projected, shaded) but have not been formally reviewed or altered by the WSGS.
