Dino Tracks & Petroglyphs

Sharpen your investigative skills because here we’ll be hunting clues left millions of years ago by two legged reptiles hunting for food, water, shelter or mates near the ancient shores of a pre-historic lake, long dried up.

If you see a sign for the Poison Spider Trailhead or Longbow Arch then you’re in the right place, follow the uneven but easy to follow trail first to the large boulder that broke off from the cliffs above, scattered with multiple dinosaur tracks.

Following the trail further up you’ll see a spectacular wall of Petroglyphs from different eras, and maybe even some modern graffiti. Avoid the temptation to leave your mark here and take a photograph with you instead.

These historic sites are on public lands but protected by federal law, defacing, adding your own marks, or even pouring water to make the stones glisten is against the law and highly unethical. Please respect these special places and their significance and teach our kids to do the same!

Dino Tracks Trailhead at Poison Spider

Sunset at Delicate Arch is very popular, once the sun dips below the horizon after most photographers have put their gear away is when I took this shot. The darker tones allow for richer colors which I loved. Most photographers

Dinosaur Tracks

It is crazy to imagine a world 190 million years ago where this boulder was the sandy shore at the edge of a drying lake. According to the Smithsonian there is some disagreement about the type of dinosaurs that left the tracks, however we can see at least three size classes of Theropod tracks on this rock. There are many types of theropods, are they from different species, different ages of the same dinosaur family? Maybe the scientist that figures it out is reading right now!

Cactus with Petroglyph wall

As you approach this wall one may get a sense of the ancient significance of such a place, Petroglyphs are often mistaken for art but indigenous people have assured us that there is a much deeper significance. I couldn’t help but notice the rocks around this area, the plants, everything is particularly beautiful.

Petroglyphs in Black & White

The mixed styles of Petroglyphs have been an ongoing discussion, but most agree these are from 100AD to 450AD, well before Christopher Columbus arrived anywhere near this continent, or was even born.

Sneak a Peek Behind the Petroglyphs

To the right of the Petroglyphs my kids found this trail that runs along the back of the cliffs. There is a vein of very sharp rocks that would make extraordinarily valuable tools and weapons centuries ago.
