The area around what is today St. George, Utah was once an arid area of shallow freshwater lakes that had extensive mud flats. As dinosaurs walked along these lakes about 150 million years ago, they left footprints in the mud, which dried out, became fossilized under subsequent layers of mud, sand and pressure. These preserves tracks can now been seen in exposed rock layers is several spots around the St. George area.
The St. George Dinosaur Discovery Site at St. James Farm is the easiest and most impressive place to find the tracks. The footprints were discovered while construction excavation was taking place on the old farm that was there. The importance of the site was recognized and it was preserved, with the museum building constructed over the top of the footprint laden rock layer. Walkways over the rock allow visitors to explore and interpreters can explain what they see and it’s significance, including the behaviors of dinosaurs.
The museum displays explain how the footprints can help scientists understand the behavior of dinosaurs. In additional to their foot prints, there are preserved claw marks and trails where they dragged their tails in the mud at the edge of ancient Jurassic period lake. The mud and arid conditions at the time preserved thousands of footprints from reptiles, dinosaurs and what is believed to be an early mammal.
The museum has numerous full-size, reproduction dinosaurs to show what the animals that made the prints looked like. There is a fenced in park area outside with activities for the kids as well.

Hunting Dinosaurs in the Desert Near St. George, Utah
We were really excited to try and track down dinosaur footprints in the Utah desert with the kids. The area around St. George has several sites to see these, and these two are probably the best to get to and are located on public land.
The Dino Cliffs trail near the town of Washington, north of St. George is located less than 2 miles off Interstate 15. However, it requires about a half mile drive down a dirt road along the side of a steep hill. Our rental car made it, but had to choose our path through wash outs carefully and drove slow.
The Dino tracks are exposed in a valley down a a hill along a red sand trail. It is about 200 yards from parking along the side of the road, but it is a steep downhill walk through mostly sand. There are other tracks less well preserved in the same layer of stone in a nearby wash and neighboring hillside.
The trail continues on if you want a great desert trek. Here is more information – http://www.redcliffsdesertreserve.com/dino-cliffs
There is another location to see dinosaur tracks nearby. The Warner Dinosaur Track site is on Warner Valley Road (note it is a dirt and gravel road but was passible in our rental car) about 5 miles east of Southern Parkway (Route 7). The road became a gravel road just past the exit. For more information – https://www.blm.gov/visit/warner-valley-dinosaur-track-site
