We have used this dispersed camp area several times off of I-70 on several occasions. Easy access whither you're traveling east or west bound. If east bound you'll have to cross over the medium which is allowed and enter the area through a BLM gate. It's always closed to keep cows off the freeway so please close it. The area has several places to disperse camp. If you follow the road it will take you to the east entrance of the Black Dragon. I once got a cell call in the canyon that surprised us as there's little cell coverage. In the Black Dragon you'll find a lot of Indian Petroglyphs. It's pretty easy hike to them or a high clearance vehicle. The San Rafael is quite interesting. The rest areas just west of the dispersed camping has a lot info about the area.
