Earth’s Story, Written in Stone

Grand Canyon — USA

The Grand Canyon is a massive natural gorge carved by the Colorado River over millions of years in northern Arizona. Stretching approximately 277 miles long and reaching depths of over a mile, the canyon exposes layered rock formations that reveal a vast geological history of the Earth. Its scale, color variations, and dramatic viewpoints make it one of the most studied and visited natural landmarks in the world. The Grand Canyon is designated as a UNESCO World Heritage Site.
