Good site, but be aware that the Corkscrew Gulch Jeep road is not an access for the turntable. There is quite a fearsome gulch between the road and the turntable--certainly not for the family. The best way is in on one of the two legs of roadbed. The tours we lead usually go in from Ironton, and up the lower leg, but I've usually come in on the upper, but part of that has been destroyed by Frank Baumgartner in road building to remove trees from some of his property. Frank is the main reason we are trying to save Red Mountain.
The Corkscrew Gulch Jeep road is one of the most challenging drives I have done, and I will not repeat it. And I use Ophir Pass as a commute run to Telluride in the summer. The only other 4WD road that compares to Corkscrew in my driving experience is the road into the basin above the Bridal Veil power plant in Telluride. This is a locked gate, fenced off road, but I have driven it a number of times recently and it ranks with the worst--hard to imagine how they got all that heavy mining machinery into some of these high altitude basins.
