The Northumberland County Commissioners holds in trust 94 parcels, or 6,500 acres, of abandoned coal land, impacted by unregulated mining practices and contained coal spoils, open strip mine pits and abandoned coal mining operation structures. A project to turn this area into an outdoor recreation facility for off highway vehicles appealed to the Commissioners eight years ago. The Anthracite Outdoor Adventure Area officially opened for business on May 17, 2014, with over 10,000 users last year utilizing the trail system.
