USAThe Grand Canyon is a veritable outdoor geology textbook. It's not the deepest in the world, but the combination of its immense length, impressive topography, and unique, easily readable rock formations makes it iconic.
Geography and scale
The canyon stretches approximately 446 km in length and up to 29 km in width, with an elevation difference of approximately 1,6–1,8 km. The area of the national park is approximately 4926 km²—almost twice the size of Moscow, giving a tangible sense of the landscape's scale.
Depth, length and width
"A mile deep" is literally true: the elevation difference from the edge to the river is over 1,6 kilometers. The width varies from a few kilometers to almost 30, and 446 kilometers is like a half-day train ride, covered entirely in panoramas.
Geological age and rock record
The canyon walls are nearly two billion years old: basement rocks are approximately 1,8–2,0 billion years old, covered by younger layers extending to depths of approximately 270 million years. Few places can trace the eras of Earth's vertical evolution with such clarity.
River and erosion
The river carved the canyon over millions of years, like a scalpel, slicing it as the plateau rose. Today, dams upstream regulate the flow, but the terraces, ledges, and meanders still tell a time-lapse story, etched in stone.
Climate and altitude
The canyon's rim is located hundreds of meters above the river: cool coniferous trees above, desert heat below. Just one day of descent can change the temperature by 10–20°C, taking you through several life zones.
Records and comparisons
A depth greater than the height of two Burj Khalifas gives an instant sense of scale. The park's area is roughly twice the size of Moscow, and its time span extends seven times beyond the age of the dinosaurs. A walk from edge to edge is about 40 km—like a city marathon with a significant climb.
Why is it important
These figures don't just boggle the imagination—they explain the Earth. Layered rock reveals the history of past seas and climates; massive relief demonstrates tectonic power; and analogies to cities and skyscrapers translate abstractions into human language.
Numbers to remember
It's 446 km long, up to 29 km wide, and about 1,6–1,8 km deep. It has about 4926 km² of protected land, billions of years of rock formations, and double-digit temperature differences between the edge and the river during the day. Every kilometer is a chapter.
Protection of Nature
A World Heritage site requires careful management. Staying on the trails, respecting water and silence, and minimizing environmental impact—that's what makes this textbook relevant for the future.
