NATIONAL PARK
Over the last 8 million years the Colorado River has slowly eroded the Grand Canyon through rock as old as 2 billion years to an average depth of 1 mile (1.8 km). The Grand Canyon National Park was established by Congress in 1919 to preserve this world famous geologic site. |

The
climate on the rim is temperate mountain with frequent snows in winter and thunderstorms through the summer. But a mile lower on the canyon floor, it is often as much as 20º to 30ºF warmer, and rain is very infrequent. |
THe
Grand Canyon attracts many visitors and is popular with hikers. There are many beautiful trails throughout the park. The most popular are Bright Angel, Kaibab, and the Havasupai trails. The Kaibab suspension bridge provides for foot traffic across the Colorado River. Running strong after more than 80 years a vintage steam engine offers scenic rides from Williams to the Grand Canyon. Mule rides also descend daily from the South Rim to Phantom Ranch on the canyon floor. |
