The Grand Canyon was carved by a river

The Grand Canyon, a colossal chasm in Arizona, was primarily sculpted by the Colorado River over an astonishing 6 million years. This immense natural wonder, stretching 277 miles long and over a mile deep, vividly demonstrates water's incredible power to carve through ancient rock layers. Geologists estimate the canyon reached near its current depth about 5 to 6 million years ago, a testament to gradual erosion at just millimeters per year.
