Dinosaur Stew

This is a continuation of my trip to Colorado and Utah from last October. This particular day was mostly a travel day, getting myself from Grand Junction, Colorado, over to Salt Lake City, Utah where I would spend several days. When I worked out the itinerary of this trip, I realized that I was close enough to Dinosaur National Monument that it wouldn't make sense not to stop and at least whet my appetite on the fossils there, and so this particular spot also made the list of must sees. And as always, I usually bite off more than I can chew when I'm on trips like this, but it just gives me an excuse to come back at a later time.

I think if I were to do this monument up right, I'd spend several days here, probably camping. The monument has lots to offer including whitewater rafting, something that I'm not into, but I do know other people are and so I've mentioned it. For me, I was most interested in seeing the quarry of dinosaur fossils. I did not come away disappointed.

The park straddles the Utah/Colorado border and so is sort of broken up into two different unique areas. Since the quarry where the dinosaur bones can be seen close up is in the Utah side, I chose to head there. As I approached the monument border, I noticed a geocache outside the park boundary, so I decided to stop and find that one. It's very rare to find a physical geocache inside a national park area, because the National Park Service views it as litter. There are a couple of exceptions as there are several hidden in Petrified Forest National Park but they are maintained by a ranger in the park. Most geocaches you'll see in national park area would be either earth caches (geology based) or virtual caches which I've written about previously. In this case, the quarry area of the park had one of each that I was interested in finding.

I spent a good amount of time in the quarry area taking in all there was to see. The earth cache I working on asked me to examine the fossils along the wall of the quarry. It's estimated there are over 1500 fossils still embedded in the wall. I talked with a ranger and he told me that it's really more of a Dinosaur stew than anything else. The herbivores would be killed by the carnivores and the bones would be left after the carnivores had their fill. Eventually, the bones would be carried downstream where they were caught in this area by a large sand bar. Over time the bones were buried and eventually fossilized, hence the jumble of different kinds of dinosaurs all in the same area. 

The two bones you're looking at in the second photo are the femurs of a diplodocus and an apatosaurus (what we would call the brontosaurus back in the day). The photos don't really tell the tale, but both of those bones are about 6 feet in length and 18 inches in diameter.

The third photo gives more of a scale size to it. One of the tourist there was from Germany who was slightly taller than me, probably close to 6 feet tall. I asked him if he would stand near the fossil so I could get a size comparison, which he obviously obliged. This particular dinosaur, a camarasaurus, was the most common fossil found in the quarry area. This was one of the most complete camarasaurus ever found anywhere. The camarasaurus is part of the long necked dinosaurs commonly referred to as sauropods.

After taking in the quarry and finishing up the earthcache, I decided to drive further down the road to a virtual cache. I did a small hike out there to get what I needed to get and then headed back to the car and the exit so I could get to Salt Lake City in a timely fashion. I caught a little bit of rain on the drive there, but that was about all of the inclement weather that I got on this particular trip. All in all, I was very glad I stopped as this was one of those "new" places that I promised myself that I wasn't going to miss if I was in the area. It's not new anymore, but that doesn't mean I won't come back again sometime in the future.
