I've been there, Mike. Big ditch in the ground with an itty-bitty river in the bottom of it that supposedly, over millions of years, carved out all that rock down to a mile deep. Never bought it and still don't buy it now.
Sansanoy, the area of the Grand Canyon you want is called Marble Canyon. It's a awesome sight. I've been there. It's pretty much the start of the Grand Canyon and runs for miles, starting right around Page Arizona.
