Frustrated by a general misunderstanding among the public of how the water in the Gold King got polluted in the first place, I put together an
acid mine drainage explainer for High Country News. I even drew my own diagrams for it, because I couldn't, for the life of me, find one on the intertubes that did simply showed what was going on. Oh, and I can't draw.
Anyway. If you read the explainer, you'll see that I make passing reference to a
1901 USGS report that makes particular note of an unusual quality of the Gold King Mine: It's dry.
At first, I discounted this, because the reference is to the "lower levels" of the mine. I took this to refer to the American Tunnel of the Gold King, which I believe was located about where the American Tunnel of the Sunnyside is now. Yet the blowout actually occurred in what's now called the Upper Gold King Mine. So the information seemed irrelevant. But then I read a little bit more about the Gold King:
Wait! It lies at 12,500 feet? But the Sunnyside Mine and today's American Tunnel, which is very close to where the Gold King Mill was located, is at just 10,600 feet in elevation. Then there was this:
Hmmm... The Upper Gold King mine is located at about 11,600 feet. Was the reference to the dry mine workings, then, actually a reference to the Upper Gold King? I'm not sure what to make of this, but I'm throwing it to my knowledgeable readers and commenters to see what you think. The full 1901 report is linked to above.
