Yes, John, you are right, this is an open OHV route and it is included into their latest forest management plan. But somehow they do not post any kind of "4WD only" sign along the road. This is why people regularly are getting stranded into the route. I remember I was reading an Internet article about a guy in Toyota Prius who almost got to the bottom of the canyon, got stuck eventually, and sued the Forest Service demanding the road closure.

What I do not understand is how the people manage to get there in sedans. Definitely their driving skills are well above my own abilities. And their recklessness is well above anything.
