deepest canyon

Most extreme chasm

The deepest canyon is the one with the greatest vertical distance from rim to floor.

Which canyon holds this title depends on how you measure—the Yarlung Tsangpo Grand Canyon in Tibet, Cotahuasi Canyon in Peru, and Hells Canyon on the Idaho-Oregon border all compete for the designation.

The deepest canyon in North America cuts through the Seven Devils Mountains.
