So something strange happening there would not be unusual and that's exactly what happened On a Saturday afternoon in 1974 a retired Wild Wood Coal Miner was walking in the woods when he encountered a rather large at first what he thought was a bear .
well over 500 pounds it stood tall than a bear and had more human like features .

But back then no one really heard or knew what a Big Foot was until shows like Leonard Nimoys" In Search of " started talking about it. This is not the first time that Coal mines and Big foot seem to have a connection there is even a theory that Big foot uses the old mines tunnels all over W. Pa. to travel back and forth. many a miner will tell of strange encounters with beats and cryptids in and around mines so big foot is no surprise
To my knowledge this is only known report of a sighting at this particular mine. and there has been no further reported activity .
In the 70s into early 90s a large Flea market operated in the old coal mine buildings along with other businesses
The wild wood mine closed in the 50s and left behind a large Gob or Bony Pile as they are known which had a fire going in it and in 1980s and was cleaned up and recycled as bio heat by a firm in Buffalo NY.
Probably all the activity to clean up the gob pile kept big foot away
after the flea market closed it has been home to several different businesses including a fitness center and auto parts distributor.
Regarding that sharp bend by the mine a side story was told me back in 70s by a long since passed away Pa. Fish Commissioner / Law Enforcer. named Charlie that when he was a young man on his way to North Park along Wild wood road he picked up a young girl who was hitch hiking and end up she pulled a knife on him and was going to rob him she made him speed up and he hit that bend at 70 mph how he ever got around it in one pice i will never know. but it was so hard of a turn the girl slid away from him and he was able to slam on brakes and she went sailing against dash and he disarmed her,
True story who knows but that road has plenty of tragic accidents along it as well as flooding
