Mountaintop removal mining permanently alters a landscape because it involves the systematic removal of entire mountaintops to access coal seams. This process requires clearing all vegetation and topsoil, followed by extensive blasting of the hard rock strata overlying the coal.1

Because this method removes the physical structure of the mountain itself, the original topography cannot be restored to its pre-mining state. While mining operations include a phase for reclaiming affected lands, the fundamental geological and ecological features—such as the mountain's elevation, drainage patterns, and original soil composition—are irreversibly changed.1
