Geography 101 with Ranger Erin
Dinosaur National Monument is probably the coolest thing in America for dinophiles. I don’t mean because of the kitschy colored brontosauruses advertising every roadside establishment within 100 miles. I mean because it has 1,500 actual fossilized dinosaur bones on display, still embedded in the rock quarry where they were found. For real!
Driving up to the park entrance, you can see right away that these rock formations are unusual. They look so much older and seem to be at an odd angle compared to the surrounding mountains. If I were simply scanning the landscape for a dinosaur bone, I might pick this spot just because it looks…likely. It turns out there’s a good reason to look here. The deep layers of rock stick up at a 70 degree angle, giving a vertical look at hundreds of millions of years of history.
Picking a particular age is like selecting a product in a grocery aisle, according to Ranger Erin. And how did these layers become exposed like this? Ranger Erin demonstrated with a thick catalog of pages, striped horizontally on the edge. Pressure from the movement of the Rocky Mountains in the east and the Uinta Mountains in the west squeezed this section of Earth’s crust up into a kind of bell curve shape. Then the top was sliced off over time by the Green River. This provides unique access to layer upon layer of fossil history. It’s called the Morrison Formation.
In 1909, Andrew Carnegie hired Earl Douglass to hunt for a dinosaur skeleton for his museum. Douglass (who was really into mammal fossils) went out to the Morrison Formation and found 8 tailbones of what came to be known as Apatasaurus louisae (named after Carnegie’s wife).
“This discovery was the beginning of a dinosaur quarry that achieved worldwide fame. In 1915, Dinosaur National Monument was established to protect and conserve that dinosaur quarry.”
Erin called it a “dinosaur logjam”. I call it breathtaking.
There is so much here to learn, so much to imagine, so much to study. This one slice of Earth is fascinating, ancient, and full of stories yet to be discovered. I had to wonder at all the young children running through the exhibit. How much do they comprehend about dinosaurs? What is popularity of dinosaurs about, really, to them? How might their visit to Dinosaur National Monument inspire them?
Dinosaur National Monument has long been on our list! One of my boys is especially interested in dinosaurs and he would absolutely love this!
It is quite impressive. I walked in, and all I could utter was “Wow!” for about 5 minutes. It’s like the thrill of finding out some legendary character is really real.
How utterly brilliant . I would love to see that!
Add it to your bucket list! It’s definitely unique.
