river canyons
Water-cut rock passages
River canyons are deep, steep-sided gorges carved by flowing water over geological time.
The river cuts downward through rock while the surrounding terrain remains elevated, creating dramatic vertical walls: The Colorado River carved the Grand Canyon over millions of years.
River canyons often feature rapids, narrow passages, and layered rock formations revealing geological history.
