What is it?
Grand Canyon is one of the most famous and the biggest
canyons in the world. Even though it isn’t the deepest
canyon of the world, is beautiful and spectacular canyon.
Here live a lot of kinds of animals, flowers, which adapted
their life in this special setting. In regard to its special
depth we can find on its slopes many climate zones from
dry subtropics to arctic-alpine. It is a great riverain vale
has created by the river Colorado. The colourful canyon
rocks were formed many millions of years ago.
This famous canyon, one of the most sights of nature,
lies in the Rocky Mountains on south-west USA in state
Arizona and became national park in 1919 and was
named as canyon i.e. Grand Canyon and is under
safekeeping international organisation UNESCO.
How was it resulting?
The mosses were crumbling rocks with
their acids and so changing for ground,
where plant found feet, which with
root system next was pulping rocky
stage. But the river Colorado did the
biggest work. The water was
permeating into little cracks and
invaded rocks and was depositing dirt
bed of red mud, hence was named
Colorado because in Spanish Colorado
means red.
Area info
Grand Canyon doesn’t line the whole
vale of river Colorado, but only sector
from inflow Little Colorado to west
border Colorado’s plain, where
reaches max. parameters and the most
delightful shaped order. It spreads on

borders about 30 km and go down
from east to west. And is long about
450km.
Width and depth of the
canyon vary from place to

miles/ 11.3 km by train. At its
deepest, it’s 6,000 vertical
feet/ 1,829 m from rim to
river. The width of the canyon
at Grand Canyon Village is 10
miles/ 16 km(rim to rim).
