Navajo Coal Series

The tribe is asking the Trump administration to dramatically expand the life — and size — of an operational coal mine that could uproot the lives of some Navajo families. And their longtime homes.

So instead of Santa hand-delivering stockings of coal along with his team of reindeer, it's NTEC — or the Navajo Transitional Energy Company — with its diesel-powered trucks trekking across the sprawling 27,000-square-mile reservation.

Coal is perhaps most closely associated with Appalachian states like West Virginia, Pennsylvania and Kentucky — or Wyoming, the nation's leading producer of the fossil fuel. But the coal-mining business was once thriving in northern Arizona as well, atop the Colorado Plateau.
