It's not anymore, but I found a retired geology professor to take me down, and he said, "Okay, I'll let you have some water from the mine." And the reason I was interested in getting water is because water which goes through mines becomes kind of acidic and will start picking up, dissolving the minerals from the mine.
Y me dijo: "Bueno, te dejo llevar agua de la mina". La razón de mi interés por el agua es que la que fluye por las minas se vuelve ácida y empieza a absorber, a disolver los minerales de la mina.
