These are the pictographs in Jones Hole in Dinosaur National Monument. You must hike to see them as they are not accessible by vehicle. These are thought to be among the oldest pictographs in Dinosaur National Monument and are thought to be around 7,000 years old.
"Starting a rappel and noticing your rope is too short isn't quite as bad as starting a bungee jump and noticing your cord is too long"
