Grand Canyon
Association is a private, non-profit organization that operates bookstores
in Grand Canyon National Park and provides financial and program support
to the park service at Grand Canyon National Park.
The creation of the Grand Canyon began 80 million years ago when
the Colorado Plateau was
formed by the upheaval of the Earth's crust. The Colorado
River then carved the path
through the Plateau creating the Grand Canyon.
The Canyon is 277 miles long and in some spots 17
miles across. The base of the canyon is 4,500 feet below the south
rim and 5,800 feet below the north rim.
As you look into the canyon, you can see the different colored layers
of rock, each marking a period in the Earth's history from 250 million to
2 billion years ago. The best way to see the canyon, feel its massive size
and see its different colors and forms is to walk below the rim, even if
it is a short distance down one of the canyon's many trails.
To get to the
South Rim from Flagstaff, Arizona take US 180 to the South
Entrance or take US 89 to Cameron, then Arizona 64.
The South Rim is 77 miles from Flagstaff and
226 miles north of Phoenix.
To get to the
North Rim, take Arizona 67 from Jacob Lake to the North
Entrance. The two entrances are 215 miles apart by car or a 5-hour drive.
The North Rim is 82 miles from Kanab Utah and 45 miles from Jacob's Lake.
