There is a site that I've been researching for some time now. It's at the end of this pipe. There should be a cluster of buildings in an amazingly remote site - hanging on the side of a quarter mile deep canyon in the middle of nowhere. There are no roads and no trails leading to it. Just this pipe. All these pictures are from the upper end of the pipe - before the canyon got deep and narrow and dark.
I got to within a mile of the site. It was getting dark and at the point I was a few hundred feet over the canyon floor in pretty rough country. I hope to finally find out what is down there next time though
