What hides this stereogram?

I recently had a visitor from the state of Texas. For three days all I heard from him was "In Texas we have the best this, the largest that, the fastest that," etc. It eventually became very annoying.
Being from Niagra Falls, I thought I could outdo him by showing him the "Mighty Niagara", knowing there was nothing in Texas that could compare to this "Wonder of Water and Power".
While standing at the brink watching millions of gallons of water rushing over, I noticed the look of awe in his eyes. It was then I asked him: "Do you have anything like this in Texas?"
He waited a moment before he answered: "No, but we have a plumber that could fix it."
