Map of Polygons that Delineate Areas of Significant Topographic Change
Detailed Description
Map of the 5,263 polygons that delineate areas of significant topographic change in the conterminous United States. Cut areas are those polygons that have a decrease in elevation, while fill areas are those with an increase in elevation.
See the Significant Topographic Changes in the United States project for more information.

Regional Geography of Topographic Surface Changes
The spatial distribution of the topographic change polygons across the conterminous United States reveals some notable regional differences and patterns of change. Overall, there is a decided concentration of change polygons in the eastern United States, which can be partially explained by the greater population density as compared to the west.
States
The spatial distribution of the topographic change polygons across the states is shown in the figure below. Some noteworthy patterns seen on the map are a dense concentration of polygons in eastern Kentucky and southern West Virginia, a distinct cluster of polygons in northern Minnesota, several larger groups of polygons in Wyoming and southern Arizona, a concentration of polygons in the highly...
