The cemeteries surrounded by coal mines in West Virginia
16 July 2014 Last updated at 00:13 BST
Cemeteries in the US region of Appalachia are historically located at the tops of hills, a tradition dating back hundreds of years.
But as mountaintop-removal coal mining destroys the hills of West Virginia, some of these cemeteries have become completely surrounded by mining operations.
West Virginia has passed some legislative measures to protect cemeteries from damaging effects of their close proximity to mountaintop mines, in which explosives strip away layers of rock to uncover the coal below.
The practice leaves the coal companies in control of access to the cemeteries.
Dustin White, an activist, and Danny Cook, his uncle, take a trip up what remains of one mountain to visit their ancestors' graves.
