Origin of the Name "Copper Canyon" (Mexico)

Copper Canyon (Barranca del Cobre) in Chihuahua, Mexico, has two naming theories:

1. Greenish-copper hue of the canyon walls.
2. Corruption of "cobra" (Spanish for copperhead snake), referencing abundant snakes and mineral wealth.

Both explanations circulate; the name reflects the area's color and natural history.
