How did the Grand Canyon form?
The Grand Canyon is a huge canyon excavated by the mighty Colorado River.
Over the course of the millennia, the force of the river water has eroded the rocks it touched and effectively created a massive hole, at the bottom of which the Colorado rivers still flows.
You can see it from the rim of the Canyon and imagine how powerful it must be to have created something that majestic!
No one knows how old the Canyon really is
How old is the Grand Canyon?
While experts know the Grand Canyons is at least 6 million years old, no one can tell for certain when it actually started to form.
In 2012 a team of scientists suggested the beginning of the Canyon may go as far back as 70 million years ago, which is much earlier than originally thought!
While there is no final answer about this question yet, it is likely that the truth is in the middle: 70 million years ago small canyons started to form but the canyon as we know it now, only came into existence as such much later.

The Grand Canyon creates its own weather
The Grand Canyon is so large, deep and varied it has its own weather system or rather several weather systems!
Depending on where in the Canyon you go, you will find different temperatures and therefore different plants and animals.
For instance, the North Rim closes in winter due to rigid weather while the Southern Rim doesn’t this despite them being only 10 miles apart (by air, id you want to drive between the South Rim and the North Rim it will take several hours, it is over 200 km!).
The Canyon has several ecosystems
The variety of weather and altitude means that the Canyon has several ecosystems.
The park ecosystems are called Lower Sonoran, Upper Sonoran, Transition, Canadian, and Hudsonian: they are so different from each other, traveling through them is like walking from Canada to Mexico in terms of diversity!
In the Grand Canyon, you will find Boreal Forest, Ponderosa forest, Pinyon-Juniper Woodland and Riparian environments, all with different animals and plants.
The Grand Canyon is home to many different animal species
Many different types of animals live in the Grand Canyon: over 400 species of birds, 91 species of mammals (like big horn sheep, squirrels, elks, mountain lions etc), reptiles and insects.
What is the most dangerous animal in the Grand Canyon?
This may be unexpected in a park with mountain lions however, the most dangerous animal in the Canyon for people is the squirrel!
While they are cute and they tend to come close to people, you must not touch them: not only you can harm them but they hurt you.

The first Europeans to arrive at the Grand Canyon were Spaniards soldiers who were exploring the area to find a navigable river that would take them to California in 1540.
The made several attempts to reach the water from the top of the Canyon but failed and ended up settling farther East in Texas instead.
After this first failed expedition, the canyons remained unexplored for over 230 years.
However, this doesn’t mean that is wasn’t inhabited: the Hopi population lived and still live in the area now.

It is within the Havasupai Reservation and it is one of the most remote villages in the whole of the USA: it not accessible by car.
The Grand Canyon is great for finding fossils
Due to its long history and the nature of its rocks, the Grand Canyon is a paradise for fossil hunters.
The oldest date back to Precambrian Time 1,200 million to 740 million years ago but you also have much more recent ones, dating back just 10000 years ago.
They are a wonderful clue to try and understand how life in this area evolved and what the Canyon must have looked like in the past.
Need to know! While fossils are great fun to spot, make sure you do not pick them up if you find them! Instead, tell a ranger about your discovery so they can make sure the fossil is safe and they can use it for more amazing discoveries
