@bendegros83: Deep beneath Pittsburgh, we investigated a suspicious tunnel that seemed to go on forever. Where does it lead, and what could be hidden in its depths? The deeper we explored, the stranger things got | PART 3
Where is this in Pittsburgh specifically? I grew up in Green Tree and every so often, late at night, our house would shake and we’d hear a train whistle coming from under it. My dad always said there were old mines under our house. We were fairly close to Parkway Center, where the mall was built on an old trash dump, so I’ve always wondered if there was truth to it.

Turners imports water from there to make their tea, that’s why you can’t get that taste from anywhere else 👌

There’s a gazillion of these old mines in Pittsburgh that’s why houses keep falling through the ground on Mount Washington. I used to live on West Sycamore, the house on the end of my street was there one day and the next it was gone.

Probably an old sewage tunnel or mine. The black stuff is definitely soot in the ground from the old factories

There could be literally any manner of microbes down there festering. Slime molds, etc. Couldn’t pay me to walk down there.

these types of places rapidly flood on occasion and you'd just be drowning and being smashed off of walls in a violent current
