Nestled in a canyon along Interstate 70 in Utah
Here’s a great link
I would skip the first canyon as you go along the road. It’s a relatively unpleasant hike. Keep going up the road to the entrance to the canyon with the Black Dragon. This makes a great road stop to stretch and see some unique petroglyphs. They have even shot movies using the title of Black Dragon. I was staying in Hanksville years ago where I met a film crew from Hollywood. Talk about a change of scenery for them. The movie was a flop, but hey, it’s always an adventure.
