Hello everyone.
It has been more than seven years since I first started this thread. A third of my life has since gone by. During this time, I have completed high school and college, and I am now pursuing a graduate degree.
I had some time before school starts against next year, and I had the chance to visit the Southwestern United States. When I saw that I had an opportunity to visit Ashley Valley, I could not resist. I had been looking forward to this since I was a little boy, and I could not wait to get started!
My trip began in Denver, Colorado...

The photo above was taken from the Colorado State Capitol. The area has a lively atmosphere, and the food there was superb. It felt like a very vibrant and modern city.
Previously, I theorized that Littlefoot's journey began near Dodge City, Kansas. I placed the location of the Great Divide near Cedarwood, CO, approximately 130 miles south of Denver, where there was a large canyon.
Boutique Air offers (virtually private) flights from Denver to Ashely Valley for just $70 a seat. However, to better experience Littlefoot's journey, I chose to remain on the ground. However, during the nighttime drive to Ashley Valley, I realized that there is no absolutely shortage of canyons in the region.
We traveled along Route 70, and we frequently encountered scenery like this:

There were many canyons with gaps of a mile or more, and any of these could have caused our dinosaur friends to separate from their parents.
It was almost midnight when we arrived in Vernal, Utah, the largest city in Ashley Valley. We stayed at the local Quality Inn. Rooms were cheap, at $70 for a room for three.
Morning came, and we were greeted by this beautiful scene:

The first thing I noticed was how high we were. Vernal is located 5000 feet above sea level, and the mountain peaks would often be obscured by clouds.
I was also struck by how large the valley was. At its longest, the valley stretches about 15 miles, and it took about 25 minutes to drive from one side of the valley to the other. By foot, it would take around 2.5 hours.
Vernal has a population of around 9000, and it had a good small town feel to it. Apparently, the local economy is fueled by natural gas and tourism, and the city liked to celebrate its connection to the dinosaurs. You can find small dinosaur cartoons on most street signs.


Note the Dinosaur Inn to the left.
I first went to the eastern side of the valley, near the Utah-Colorado border. The staff at the following visitors center were very helpful. This sign was placed at the entrance of the visitors center.

There is still a lot of green in the valley, although most of it has been converted to farmland. Overall, there was a lot of green space, but there were fewer trees than I expected.

(Sorry... To be continued...)
