Agreed. I've been to many canyons, and the Grand Canyon is truly a marvel - it's stunning, it took my breath away and still does. Just go and look at it for 15 minutes? That's all you can muster? "Featureless" steep inclines? No mention of the biodiversity? What?!

The Grand Canyon is in the rare club of places I've been that surpassed my high expectations.

I say to anyone who asks me about the GC "it will completely surpass any expectations you have of it, even if you take this into account". Nothing can prepare you for the scale of it, even if you've been there before and/or been in the Utah canyon parks. No photo, no video can capture the experience of being on the edge of it nor being down in it.
