A spectacular water gap/slot canyon north of Ely, Nevada. I suspect it's antecedent--that is, as the ridge rose under the stream it kept cutting down.

In Wilson Canyon, a water gap where the river crosses the Singatse Range from Smith into Mason Valleys. The West Fork rises in the Sierra Nevada and flows east out into Nevada. It joins the East Fork in Mason Valley and the combined river ends at Walker Lake, a closed-basin lake whose only outlet is evaporation. (I've got an album on it, too.) Nevada State Route 208 also goes thru the canyon, paralleling the river.

Yampa River, Colorado, USA. Looking upstream. A classic water gap, to use the geo-jargon.
