Potash Road Dinosaur Tracks and Petroglyphs

Potash Road Dinosaur Tracks and Petroglyphs is an archaeological site where you can see ancient footprints pressed into tilted sandstone alongside rock art carved by Native Americans above the riverbank. The two types of markings sit on the same slope overlooking the Colorado River below.

This place took shape roughly 190 million years ago when the region was a sandy lake shore during the Jurassic period and dinosaurs left their tracks behind. Thousands of years later, people began adding their own rock art to the stone face over many centuries.

The rock art here shows the creative work of several Native American groups who left their mark over hundreds of years, with distinct styles visible side by side on the stone.

You reach this site by a short hike starting from the Poison Spider Mesa trailhead, though you will need to scramble over some rocks to get to the actual tracks and art. Wear sturdy footwear because the ground is uneven and can be slippery when wet.

Here you can actually see Allosaurus footprints that became locked in stone as mud turned to rock over millions of years, creating a direct window into a single moment in prehistoric time. Few places let you touch and observe tracks this old and this clear.
