Virgin River Narrows - utah, usa

The Virgin River Narrows is a long “slot” canyon in Zion National Park.  The canyon is narrow, sinuous, and steep-walled, formed by the Virgin River as it cut through the comparatively soft sandstone of the region.  The 16-mile route through the canyon narrows in places to 20 to 30 feet wide, with nearly vertical walls that rise over a thousand feet.
