CHARLESTON, W.Va. (AP) -- Activists trying to protect West Virginia's historic Blair Mountain from further coal mining are keeping the fight alive.
On Thursday, they announced they're appealing their latest loss in U.S. District Court in the District of Columbia.
In 1921, some 10,000 unionizing coal miners marched to Blair and battled an army of police and hired guns on the mountain. Sixteen men died before the miners surrendered. It was the largest armed uprising since the Civil War.
The 1,600-acre battlefield was briefly added to the National Register of Historic Places, and then removed when private property owners objected.
The groups trying to have that status restored lost their court fight last month when a judge concluded they lacked status to challenge the de-listing.
