Simple Bouguer gravity map of Minnesota, St. Cloud sheet, M-44
Description
Bouguer gravity anomaly map (anomaly related to different densities of rocks in the upper crust, Bouguer anomaly is a corrected difference between an observed gravity measurement and value predicted from a generalized earth model), shown as contour lines (isolines) of equal value, St. Cloud quadrangle, scale 1:250,000.
