Located in Grand County Utah, about 4.5 miles west of the Colorado border, there is a large boulder near the Triangle Road, BLM 107, that has about 50 well defined sauropod dinosaur tracks. Individual groups of the tracks form 4 or 5 distinct trackways.
The best approach is from Glade Park, Colorado which you can easily enter into your driving app. Continue past the Glade Park store on the paved DS Road for 20.2 miles to the Colorado/Utah border and turn right.
Follow the Triangle Road for about 4.5 miles and park off to the side. In dry weather 2wd vehicles should be able to easily manage the road up to this point.
The large boulder with the tracks is visible from the road. (That's how we discovered it ourselves.) They show up very well with a pair of binoculars before ever leaving your vehicle.
There isn't a designated route to the tracks but there are several social routes from which to choose. Some minor scrambling is required the closer you get to the boulder.
Here you can see 2 trackways across the top of the boulder, one in the middle, and another below that. There might be another trackway that angles from the right end of the lower trackway up to the left end of the upper trackway or it might be a continuation of the lower set of tracks.
Here is a closer look at the top of the boulder.
And here are the well formed tracks near the bottom.
The track in the middle seems to show toe impressions.
A few smaller tracks look like those of a juvenile.
There are some thin layers of the same formation scattered around the large boulder. At least one of them also has a track.
The boulder with the tracks obviously eroded from the top of the mesa and fell into the canyon where it presently lies. It would be interesting to go to the top of the mesa and see if anymore of that formation exists with the possibility of finding more tracks. As it is it's nice to find tracks that are so easy to visit when exploring the Triangle Mesa area in eastern Utah. If you would like to see them for yourself then all you have to do is 'Take a hike'.
