Brachiopods, Mollusks and Donkeys, Oh My!

We traveled along more than 60 of the 277 miles of the Grand Canyon, seeing one site after another along the Southern Rim of the Canyon.  At Mather Point (7120 ft) gypsy birds temptingly bopped along the cliff, hoping we would follow them for a hike. Instead we drove down Desert View Drive, walked through Grandview Trailhead, and visited Tusayan Ruin and Museum.  Despite the provoking chickadee, the alluring hiking trail loops and donkey rides, we departed The Grand Canyon National Park that afternoon.

There are not many things proven more patient for change than the Grand Canyon. The specific geologic processes and timing that formed the Grand Canyon are the subject of debate by geologists today. However, Marine fossils have been found in layers of rock in the Grand Canyon, indicating that it was once the bottom of a sea.  No dinosaur fossils were found in that mix; it was Sir. Mollusk and Madam Brachiopod who ruled while suspended in water above this now dry land.  The rock layers range from 1.2 Billion to 270 Million years old.  The Dinos were a little too late to be fossilized parts of  this natural world wonder, arriving nearby 230 Million years ago.  Then lazy ‘ol Colorado River dropped by about 130 Million years later, after the birth of the Rocky Mountains.

Disappointed that our expectations of dino fossil findings would come up short, we talked into existence exactly what we were hoping for-a Dinosaur Footprint Park! Yeah, only a few miles off our planned path, Tuba City was our next stop…
