Pennsylvania is home to approximately 250,000 acres of abandoned mine lands as a result of decades of unregulated mining.
- Abandoned mine openings may be unmarked or unprotected at the surface and can be hundreds of feet deep.
- Openings covered by decaying material may give way under the slightest weight.
- Unmarked mine shafts and tunnels can be hundreds of feet deep and will swallow you without a trace.
- Unstable cliffs, water-filled pits, old explosives, and abandoned buildings all add to the danger.
- To report the location of an abandoned mine or quarry, please contact Pennsylvania’s Department of Environmental Protection, Bureau of Mine Safety at:
