Grand Canyon East-West Mounded Uplift

 

Sorry about klutzy drawing.  Hope it's clear.  The idea is that the water that carved the Grand Canyon had to cut into the uplift from east to west, but since the uplift slopes north to south it's hard to see how a small river would have done anything but run off the south slope, OR cut something, but north to south rather than east to west.

 

Old Earthers argue that the uplift occurred very very slowly over millions of years, as if that would somehow guide the water in the right direction.  Looks to me like my own theory that the uplift cracked the upper strata which allowed still-standing Flood waters to rush into the cracks and scour out the canyon in a lot less than millions of years is a far more likely story.
