This particular petroglyph is known as the Three Kings, the only petroglyph at the site that has been given a formal name that I am aware of. Given that there are clearly more than three figures in the scene, I don’t know the reasoning behind the name given.
The McConkie Ranch Petroglyphs are located on a private ranch northwest of Vernal, Utah The are some of the finest and largest examples of Fremont Indian rock art that I am aware of. The Fremont inhabited parts of Utah, Colorado, Nevada, and Idaho from approximately 1 A.D. until 1300 A.D. Like their southern neighbors the Anasazi, the Fremont built semi-permanent settlements and engaged in agriculture, which distinguished them from the hunter/gather tribes of the past. Their rock art can be found in many locations including Newspaper Rock, Nine Mile Canyon, the San Rafael Swell, Rochester Creek, and nearby Dinosaur National Monument.
