WASHINGTON (AP) - Activists from Appalachia are calling on the Obama administration to end the practice of mountaintop removal coal mining.

The administration has set out to curb the practice, but the activists said it hasn't done enough. They announced plans at a news conference Monday for a rally in Washington next month, and are inviting President Barack Obama to attend.

In mountaintop removal mining, forests are clear-cut, explosives blast apart the rock, and machines scoop out the exposed coal. The earth left behind is dumped into valleys, covering intermittent streams.

Mickey McCoy, a former mayor of Inez, Ky., called mountaintop removal mining "environmental terrorism." Coal operators say it's the most efficient way to reach some reserves.
