The findings could lead Congress or the Department of the Interior to take steps to make sure unreclaimed mines get reclaimed, she said. The lawmakers have asked GAO to quantify the number, location and size of coal mines that have neither produced coal or made reclamation progress, and whether bonding or other financial assurances are adequate to address the problem.

In the closeup images, the mined land seems to move over time. As the mining and beginnings of the reclamation process take place, we can see the digging and backfilling occurring.
