Isn't there a "mountain range" through that area? Would the river have gone up and over the mountains?

Yes. (The content researcher did address this Snafu in Part 2. I could be wrong but I believe he acknowledged the area elevation is now 500-600 ft)

He also theorizes that in the tumultuous aftermath of a calamity (earthquakes?), the original river route and flow could have also been displaced, rearranged or just disappeared at that time. The cataclysmic upheaval could have possibly resulted in "new" hills and mountains.
