"The ages have been at work on it and man can only mar it. What you can do is to keep it for your children, your children's children, and for all who come after you..."
- President Theodore Roosevelt in 1903
This is an oft-quoted comment on the Grand Canyon.
In order to retain as much as possible of the Canyon's glory, there are some simple rules to follow:
Put your trash in trash cans and your recyclable refuse in the specially marked recycling bins next to the trash cans in the park.
Pack out what you pack in (as well as any litter you encounter).
Do not disturb canyon vegetation or feed the animals. No pets of any kind are allowed below the rim of the Grand Canyon, except for certified seeing-eye and hearing guide dogs.
Avoid disturbing them in any way prehistoric sites or 19th century mining camps.. Defacement of the sites or theft of artifacts carries civil and criminal penalties.
Be conservative in using water (although be sure to drink enough of it!).
