The Grand Canyon is one of the USA’s treasures. Most Americans and many foreigners want to visit this awe-inspiring natural wonder at least once in their lifetime. In 1979, this national park was also designated a UNESCO World Heritage Site.
I’ve planned several trips for clients to the Grand Canyon, so I figured it was time that I write an article about this iconic destination. Let’s learn some fun facts about the Grand Canyon.
1. The Grand Canyon is even older than you think.
When you stare into the Grand Canyon, you’re not just looking at rocks; you’re looking at billions of years of Earth’s history exposed before your very eyes. While the canyon itself was carved by the Colorado River over the last five to six million years, the rocks making up its walls are much, much older – some dating back as far as 1.8 billion years! That’s right, we’re talking about rocks older than multicellular life on Earth.
While the Grand Canyon is rich in fossils, including ancient marine creatures and plants, you won’t find dinosaur fossils here because the rock layers predate the age of dinosaurs.
Scientists study these layers to understand everything from ancient seas to volcanic eruptions. Imagine the stories those rocks could tell!
2. The Grand Canyon is bigger than you think.
“Big” doesn’t even begin to cover it. The Grand Canyon is approximately 277 miles long, up to 18 miles wide, and a mile deep. It spans approximately 1,900 square miles. To put that into perspective, you could fit the entire state of Rhode Island (1,214 square miles) inside the canyon, with room to spare!
In some spots, the canyon is 6,000 feet deep (more than a mile). To put that in perspective, that’s like stacking the Empire State Building over five times.
If you were to walk its rim from end to end, it would be a journey longer than driving from Los Angeles to Las Vegas. Its sheer scale is difficult to grasp until you’re standing on the edge, gazing into the vastness. It’s not just a big hole; it’s an intricate, sprawling labyrinth of rock formations, buttes, mesas, and ravines.
3. The Grand Canyon has different microclimates that support diverse plant and animal life.
Due to its incredible depth, the Grand Canyon boasts a fascinating array of microclimates. That means that the weather and temperature at the rim can be vastly different from what you’d experience down at the Colorado River. For instance, the South Rim has a mean high temperature of 63°F, while the Phantom Ranch at the bottom averages 82°F.
This variation in elevation and climate creates diverse habitats, supporting a surprising variety of plant and animal life, from desert dwellers to those that prefer cooler, higher elevations.
The result is an impressive variety of plants and wildlife — over 1,700 plant species, 447 bird species, 91 mammal species, 58 reptile species, 9 species of amphibians, and 17 species of fish!
From the elusive mountain lion to tiny canyon tree frogs, this ecosystem is as vibrant as it is vast. Birdwatchers, photographers, and nature lovers are always thrilled by the variety of species calling this vast space home.
Keep an eye out for the adorable and unique Kaibab squirrel, which is found only on the Grand Canyon’s North Rim! These squirrels have distinctive white tails and tufted ears.
This canyon also serves as a crucial habitat for endangered species like the California Condor, a majestic scavenger with an impressive wingspan.
4. The Grand Canyon holds special significance to Native American tribes.
Long before it became a national park, the Grand Canyon was home to Native American tribes. Archaeological evidence suggests human presence dating back over 12,000 years. The Grand Canyon holds deep cultural significance for 11 Native American tribes, including the Havasupai, Hopi, Navajo, Hualapai, Zuni, Pueblo, Cohonina, and Paiute. These tribes consider the canyon a sacred site and treasure it for its spiritual significance and abundant resources. Visiting the canyon can be a respectful journey into indigenous history and culture.
5. The Grand Canyon is a Stargazer’s Paradise.
The Grand Canyon is an official International Dark Sky Park. Why is that important? Because it means the park actively works to preserve and protect its incredibly dark night skies from light pollution. On a clear night, away from city lights, the sheer number of stars you can see overhead is absolutely mindblowing. The Milky Way stretches across the sky like a glittering band, and you might even catch a glimpse of shooting stars. It’s a truly humbling experience to connect with the cosmos in such a pristine environment.
6. The US Postal Service still delivers mail by mule inside the Grand Canyon.
In the remote village of Supai, located within the canyon, mail has been delivered by mule since the 1930s. This tradition continues due to the village’s inaccessibility by road, making it the only place in the U.S. where mail is delivered this way. The Supai Post Office even has a special Mule Train postmark.
