Lived there in 1971-73. There is a gravel pit just before you turn to the right with the big rounded rocks. Go into the gravel pit, if it's still open. I found a 22 inch smoky crystal in there. And go due north cross country and less than a half mile on the edge of the field there's a solid rock mine shaft on south side oif hill. After seeing panther tracks we, stupidly figured he wouldn't bother us, and went in about 50 feet. The Amethyst crystals are unbelievable! We carried a bucket full back on our horse and walked her home. It is all Forest Service land, so just tread lightly. Bears, cougars and lynx have crossed our path up there. Nowadays, the old bus junkyard, a real eyesore, is the new Junior High School. Really shocked me when I drove from my old house and saw that. You can get to the Air Force Academy from Rampart Range Road. Ask my Dad. He had to bail us out when my brother and I were arrested for trespassing while deer hunting. No hard feelings though. I spent 21 years in the Air Force and retired as a Captain.
