ETA OK I sound like an asshole - Nicer this time

It CUT the Grand Canyon dude - it wasn’t that huge, it CUT THE CANYON OVER TIME. Read a geology textbook. The plateau is sandstone, which you can cut with running water in days or weeks in some places. The river starts out in hard rock then hits soft sandstone and Cut the deep canyon you see over lots and lots of years. I live at the headwaters of the CO river, my friends guide on it…The GC was not full of water like lake powell once was...
