Safari Sto Gran Tour

How was the Grand Canyon formed? What you didn’t want to know about the world’s most famous chasm

Millions of years of hard work that created one of the coolest ecosystems ever

Have you ever wondered how the Grand Canyon became so... grand?

If your answer is yes, then you’ve made a big mistake and fallen right into our trap: it’s time for another episode of the saga “Sto Gran Tour’s wildly over-the-top explainers”!

Brace yourself for the worst and enjoy the badly explained story of the Grand Canyon!

Drop by drop, rock gets carved and the desert gets outplayed

The star of our story is the Colorado River, a true sculptor of nature, just without the beard and artist’s beret.

To create the masterpiece that is the Grand Canyon, it got out of bed millions of years ago (and you complain when you have to wake up early for work), put on its work overalls, and kept at it year after year, carving through rock.

Quite the job!

Then, a little less than a million years ago, the Colorado got some help from volcanoes in the area, which also contributed to shaping the gorge, leaving behind clear signs of volcanic activity that are still visible today.

Our heroes had to deal with layers of rock from different eras, each with its own story to tell. There are limestone rocks that speak of ancient seas, sandstones that recall sandy deserts, and volcanic rocks that bear witness to fierce eruptions.

The result?

A breathtaking canyon stretching for 446 kilometers, with a width ranging from 18 to 28 kilometers and a depth of more than one kilometer. A true masterpiece of Mother Nature, leaving us speechless in the face of its power.

Big birds (the feathered kind, obviously), bats, and jumping mice

Okay, okay, we know it: the Grand Canyon is famous for its red rocks and dizzying heights.

But did you know it’s also a true paradise for biodiversity? Here, nature really let loose, creating a mix of flora and fauna you won’t find anywhere else.

Let’s start with the latter.

Have you ever heard of the California condor? Yes, those giant birds with an enormous wingspan. In past decades, these poor creatures were on the verge of disappearing.

And guess whose fault it was?

That’s right, as usual, us humans, who just can’t seem to keep from messing up the animal world. Luckily, thanks to major conservation efforts, condors have returned to soaring above the Grand Canyon, making the sky a little more fascinating (and a little more crowded).

And then there are loads of other amazing species, such as gray wolves, Abert’s squirrels, and tiny bats that roam the caves around the area.

And not just “ordinary” creatures, either!

In the Grand Canyon, you can also find oddities like Merriam’s kangaroo rat, a rodent that hops like a kangaroo and looks like a hamster having a very strange day. Or the Sonora chub, a fish so tiny you could lose it in a glass of water.

Immortal shrubs, judgmental cacti, and deceptive pines

Then there’s the flora.

If you think the desert is nothing but sand and rocks, you’re way off. The Grand Canyon is a real botanical garden, with more than 1,700 plant species adapted to every kind of climate and terrain, from tiny flowers that look as if they were painted by an artist to super-resilient shrubs that have probably been around forever.

And then, of course, there are the cacti, standing there motionless, probably silently judging every visitor who walks by.

Along the canyon rim, entire conifer forests rise up, and you’ll also find mountain meadows that bloom in spring.

Some of these plants are truly special.

Take the agave, for example: it can live for hundreds of years and bloom only once, in an explosion of yellow flowers that attracts bees and butterflies from across the canyon. Or the yellow pine—which actually isn’t yellow at all—whose needles release a fragrant oil that helps prevent fires.

So whether you’re a botany enthusiast or simply curious, the Grand Canyon’s flora has plenty to surprise you. And if you need a bit of shade to cool off from the desert’s endless scorching temperatures, you can always take refuge under a fresh Colorado cottonwood tree.

In conclusion

The Grand Canyon is seriously impressive, truly next-level stuff, especially if you get the chance to experience it in person.

A bit like we do during our California itinerary, where participants get the chance to stop right here, exploring the canyon from above on board a plane.

Pretty awesome, right?

Check out the full program of our group trip to the Golden State and start getting your backpack ready. We’ll be waiting for you on the next departure!
