@donkeypong, I think you bring fiction story geological side and I'm really prefer to read those part. Brody got massive knowledge through supporting explanation of Jill. I believe Brody slowly come to Fenn's treasure.

Jill was a grad student in geology at the University of Denver. Without being annoying, she explained the main geology of the region and the various rock patterns here at the edge of the Rocky Mountains. Brody found her attractive, but he didn’t plan to spend very long here in Denver.

Finally Brody met perfect knowledge include geology. Why Brody don't like to stay long time in Denver? He want to be billionaire after find treasure. I trust next time you bring us different place. Thank you for sharing.
