Long before there were people, there were swamps. Those carbon-rich landscapes were eventually buried by mud and sand and rock. The weight of the overlying rocks compressed the swamps into coal seams. Hundreds of millions of years after the first swamps were buried and moved around the earth by geologic and tectonic forces, humans discovered that coal seams were an abundant source of fuel. In West Virginia’s Appalachian Mountains, multiple layers of coal lie underground in ancient rocks. In some places, miners remove mountaintops to get at that coal. Acquired by NASA’s Landsat 5 satellite, these natural-color images show the growth of one such mine, Hobet, between 2000 and 2010. The surface mine shows the most development around Mud River and Connelly Branch. A feature in our World of Change series—Mountaintop Mining, West Virginia —documents the growth of Hobet mine from ...
