8. Copper Canyon – Mexico
Strictly speaking, this canyon in Chihuahua, Mexico is not just one but six canyons, which are known collectively as Copper Canyon. Barranca del Cobre, as it is called in Spanish, is named after the coppery green hue of its walls. And the six rivers responsible for creating these amazing valleys flow into the Sea of Cortez as part of the larger Rio Fuerte.
The deepest canyon in the system, Barranca de Urique, is a whopping 6,164 feet (1,879 m) deep. Copper Canyon is rich in wildlife, but, sadly, many of the species are now endangered due to deforestation. Hopefully, something can be done to help these animals before this canyon loses one of its most important features.
