I don't know what they mean by the end of Dark Canyon and it's been a few years but in the late eighties a very good friend of mine that I worked for used to live in the very last cabin in the canyon where the road stopped. I stayed there several times and it was the only dwelling in the canyon that wasn't wiped out by the flood of 1972, or so I was told. I absolutely loved the spot and there was a perfect naturally formed pool in front of the cabin and that was wonderful on a hot summers day!
I remember a viet nam vet that lived off the land out there in the canyon and you never knew when he might be around watching you. I stayed a number of times at the last place out there where the road ended in the late eighties, it was the only place in the canyon that survived the 72 flood
I lived in Rapid City many years ago. Dark Canyon was a wonderful secluded place to go to. Now, I guess, it''s getting ruined by development. GREEDY DEVELOPERS AND REALTORS!!!
