Day 12 - Thursday 9th June 2016

The only real geology on our journey from Vernal to Granby was at Dinosaur National Monument but that geology was rather spectacular. I remember on one excursion looking with awe at a hollow in the rock and being told that "this may be the footprint of a dinosaur" and hoping that one day I would see something a wee bit more convincing. If you want something more convincing Dinosaur National Monument is the place!

It is not far from Vernal to the park entrance. At quiet times of the year you can drive to the quarry but generally you have to park at the Visitor Centre and take a shuttle to the quarry exhibition hall. The Visitor Centre has much about the geology of the monument and you can see Doug's version of this HERE.

Dinosaur National Monument

This building covers what is left of the Dinosaur Quarry. Much of the quarry material has been removed to grace museums all over the world. But there is still a lot left!

The quarry face inside the building. Photography of the whole face tends to be rather disappointing as the bones are much the same colour as the rock. But closer examination shows how much there is to see.

More bones on the quarry face, especially vertebrae. The plenitude of bones is thought to be caused by a flash flood racing down a river valley, picking up all the bones of dead dinosaurs scattered about the place and dumping them downstream as the force of the flood subsided.

IDinosaur National Monument

A Camasaurus thigh bone, extracted from the quarry gives an indication of the size of these creatures.

Not all the dinosaur fossils are under cover! This fossilised bone was found on the path back to the Visitor Centre. Note the coin for scale.

After our visit to Dinosaur National Monument we continued our long drive to Granby. Doug explains the geology we crossed HERE but we did not stop to examine it in any detail. The scenery was rather good but we were glad to get to our, rather isolated, hotel in the scattered settlement of Granby.

On the road to Granby

I think this is Whiteley Peak, a rather nice looking mountain which was good enough to persuade us to stop and look.
