According to standard theories by all rights, the "debris field" should be out there where the Colorado empties into the ocean. That's a big problem with the standard theory; it ain't there. In real life, most of the material got vaporized and/or blasted into space. That's why you don't find the world's biggest rock pile out in the ocean where the Colorado should have put it.

The Colorado empties into the Gulf of California. (Hope I'm not doing another Romania here.)

Where are all the sediments that have washed down the Mississippi? Why, all of Louisiana isn't that big!

When the Grand Canyon had just got started, the coastlines were very different. Very, very, different. Plate tectonics and all that. The continents we know now were barely recognizeable.

Sounds pretty hot. Why was nothing adjacent melted?

A blast like that and there's no debris field to either side? And there's no glass?

The Trinity test vaporized some stuff too, but it left a layer of glass. The stuff next to the stuff that vaporized melted. And Trinity was a tower burst if not an air burst. About a 100-foot tower IIRC. You're talking about something that dug the Grand Canyon.
