We are looking down the last flight of stairs near the bottom of the shaft. The walkway/staircase spirals down around the outside of the elevator, which is enclosed by the metal fence on the right. The top of the shaft is just under the surface, but the bottom is about 60 feet down. Standing at the bottom, just outside the main blast doors. The stairs do continue down, but disappear into the water just beneath the main level. The water that floods part of the complex is usually very deep and very dark; in most silos it was impossible to tell just how deep it was. There is also TONS of asbestos pipe insulation stacked in every available corner of the complex. MOST places were damp and humid, which keeps the asbestos from becoming airborne, but other parts were dryer and it was possible to kick up some dust. Asbestos is a dangerous carcinogen (it causes cancer). Some rumors have also been heard that these underground sites have been known to have dioxin contamination, too. Also, most of the complex is lined with iron that has been rusting for decades. It would not be smart to enter this place without a breathing mask, clothes that you never intend to wear again, sturdy boots, a helmet with a light, sealed gloves, and a recent tetanus shot.
