The Rise and Fall of the Great Basin
central Nevada, indicating that part of today’s Great Basin was the highest land in North America some 40 million to 20 million years ago.
A lot has happened out there.
I think it was in Querencia that Steve said the Basin was a favorite place.
An update*
I didn’t think of it when posting before but this basin uplift work seemed to mesh with the Paleo-Bell River theories I had seen before. Sure enough, the timing, etc looks right. As the map shows, the river ran off of Nevada to the Labrador sea! Now, that was a river! River doesn’t do the reality justice. The French have a separate term for the great rivers, a Fleuve. I think that is what is needed here. It makes to you wonder what the greatest rivers ever were like back in the days of the Pangea supercontinent.
Also, speaking of great rivers, the Congo is fairly unique with a level basin behind an uplift of land it had to cut through to get to the sea. Among other things, it produced the world’s deepest river.
