Map of Grand Canyon
When did the Grand Canyon
become a park and why?

The Grand Canyon was established February
26, 1919. Grand Canyon became a national park in
order to give it the best protection we, as a nation,
have to offer. The mission of the National Park
Service, here and elsewhere, is to preserve the park
and all of its features, including the processes that
created them, and to provide for it’s enjoyment by
park visitors in a way that will leave the canyon
unspoiled for future generations. Now, more than
ever, we recognize how complex and difficult a task
that can be.
