Yes, this is one of the places in the US I would love to visit to photograph! Thor, your image makes me feel even more so.
There are other slot canyons that are not as touristy as the Antelope Canyons. Of course, the reason I visited Lower Antelope Canyon despite its touristy reputation is because its there.
This is dating myself but Page, Arizona is one of my favorite places to visit is that the western movie, The Outlaw Josey Wales, acted/directed/produced by Clint Eastwood is one of my favorite next to The Unforgiven also by Clint Eastwood. Both western movies are his atonement for his earlier western spaghetti movies shot mostly in Europe. The Outlaw Josey Wales filming locations were mostly around Page, Arizona - Kanab, Glen Canyon, and barren southwest scenery.
