“the great flood” in the books I’ve read at the Grand Canyon parks service refers to “the inland ocean” they speculate once covered most of the southwest.
I remember reading a pamphlet, and realizing “Oh. Not the Great Flood”.

That there was a vast seaway linking the Gulf of Mexico to the Arctic Ocean isn’t a matter of speculation; it’s an observable fact. The vast expanses of sedimentary rock, rich in marine fossils, attest to that. Not to mention vast salt beds, found at depth in various parts of the basin.
