I imagine that, at the time, it would have looked quite like a gaping (deep but not wide) hole in the ground. I think that's what Dale was referring to.

Then, the No.5 Shaft and over to the No.4 was full of gob fill to form a road of sorts that was used by the mining school. The tour ended at No.5 Shaft, and as I recall, the No.7 was off to the left along a drift a ways. Now, off on the main branch going over to the No.2 Shaft there was a winze or two, but there were no gaping holes anywhere near the tour area. The adit where the tours run now was originally a drain adit just the size of a drift (4'x6') and was intended simply to drain water that was collected in the sumps by bailing skips when they bailed out the shafts. I'm not sure when MTU widened the adit to its current size, but I think it was some time in the early 70s. Dale,

It ran out the adit and the tour guide mentioned that this was the water entering into the mine draining out the adit.

But from your comment, if one had taken the tour in the 1990's with the mine only full to the 14th level, the #5 shaft where the tour ends would have been a gaping hole? Not the "small puddle" that one sees today? Summerfiend: I don’t recall when the QMHA started doing tours through the adit.

I was told that (and mine maps support it) that as the mine deepened, it also expanded in length so that the upper levels were shorter than the lower levels, the end result being that the upper levels would fill with water faster than the lower ones. I don't recall to what level Homestake had unwatered the Quincy when it was doing exploratory work at the No.8 Shaft, but it must have been a remarkable feat to do it to any level. From what I was told by old miners, the floors of drifts were slanted toward the shaft to make pushing tram cars easier; as a level filled with water, the slope of the floor caused the water to course as it would along the deck of a sinking ship, and this current is what would wash stulls and things away. I remember once being in the Quincy, off the end of the tour, and standing at the No.7 Shaft. While no water was running down the shaft itself, you could hear it roating in the lower levels, and the sound was very loud. I remember being amazed at the sound of water moving that fast.

It started out as just a drain for the mine. The water level in the mine is right up to the 7th level -- if you take the tour, it ends right next to the spot where the #5 shaft cuts through, and the water is right next to your feet!

So the tour entrance is the drain? Ya, i know it doesn’t compress well but im not sure if it would help support it.

But in general, water doesn't compress very well, so I suspect that the parts filled with water are usually stable.
