Who could ever suspect such an illogical thing?
Funny how so often there's some kind of a river running through those steep-walled features, though. The Potomac flows through something called "The Narrows" near where I live. I could almost see how someone might think the river cut that gorge. Then there's the gorge of the Colorado, the gorge of the Brahmaputra, the narrows of the Yellowstone, the black canyon of the Gunnison ...
Which is the Grand Canyon. Was going for "The Gorge of the Arkansas" there. (Pretty to drive through.)
