The Grand Canyon

 

The Grand Canyon, located in Arizona, United States, is a geological formation with extensive and detailed rock layers, revealing 1.2 billion years of Earth's history, including marine, nearshore, and desert environments. Formed over billions of years by the erosion of the Colorado River, the canyon spans 447 kilometers (277 miles) in length, reaches widths of up to 29 kilometers (18 miles), and depths exceeding 29 kilometers (18 miles). Its sheer size and depth are not only awe-inspiring but also of significant scientific interest. The canyon's deep rust-red colors and sediment layers are visible across its cliff walls, which from the perspective of visitors, travel endlessly into the horizon.
