September 7, 2013 – Big Water Visitor’s Center Dinosaur Museum and Dick’s Attempt at Four-Wheeling

After a morning of doing little beyond reading in the shade and enjoying a pleasant breeze, we drove north to Utah (actually just a couple of miles away) to the Visitor’s Center in the metropolis of Big Water (population just a tad over 400).  There the National Park Service has its headquarters for the paleontological digs on the Grand Staircase Escalante Plateau.

In conjunction, they have a small but incredibly interesting dinosaur museum where two of its resident paleontologists, including Dr. David Gillette, provided a wealth of information about the Age of the Dinosaurs which was his academic specialty.

Comparative profiles of a Parasaurolophus (a plant eater) and a Dromaeosaurus (a carnivore) along with Debbie and several of our friends

Ammonite – An ocean mollusk which lived some 94 million years ago

The 8 1million year-old Skull of Diabloceratops (an ancient herbivore ancestor of the better-know Triceratops. It ranged in height from 4’ to 5’; Ran 9’ to 10’ in length, lived in Mesozoic and Late Cretaceous Eras

Masutoceratops, another forerunner of triceratops, approximately 6’ in height, 15’ long and weighing 2.5 tons

A few of the surprising facts we learned:

·        Much to our surprise, the Colorado River has not channeled its path through the rocks to create the Grand Canyon.  Rather, the canyon floor has remained at a relatively constant elevation while the Rocky Mountain plateaus around it have risen … at roughly the same rate as a human’s fingernails grow.

·         From the time a partial fossil is discovered, it may take 1-2 years to unearth the entire skeleton and another 4-5 years to clean, assemble and mount the fossil.

·         When a new species is unearthed, the person who discovered it does not get to name it.

·         On average on the Grand Staircase Escalante Plateau, roughly one new discovery is made each month.

·         Dinosaurs with feathers date back almost 200 million years ago.

·         There is no such animal as a brontosaurus (which we did know).

On the way back to our campground, we stopped by Lone Rock,

a rectangular monolith rising out of the northwestern end of Lake Powell.  After driving past many of the more than 100 RVs camped along the shore

I decided to take whirl at four-wheeling in the soft sand.  It was a ball

… until I hit a spot where my Jeep came to an inglorious halt.  

I finally managed to slip the transmission into 4-wheel-low and negotiated our way out of the sandy quagmire into which I’d mired our vehicle.
