Topographic features, under certain circumstances, may reveal information about what is hidden beneath. By studying the configuration of the surface, information can be gained as to what might be below, and visa versa the configuration of subsurface features can give insight as to what may be expected on the surface. Thus, surficial topographic features may be indicators of buried folds, faults, igneous intrusives, and other subsurface geologic features. The Big Springs (Shawnee/Douglas counties) and Beagle (Miami County) anomalies in eastern Kansas are given as examples.
