hi brishti!! your answer:

The Grand Canyon continues to be a landmark that draws several millions of visitors every year. Rock matter found there dates back to approximately two billion years, and the nearly 300 miles of land hold around 70 different species of animals. Touring the Grand Canyon is an experience like none other.

Incised by the Colorado River, the canyon is immense, averaging 4,000 feet deep for its entire 277 miles. It is 6,000 feet deep at its deepest point and 18 miles at its widest. However, the significance of Grand Canyon is not limited to its geology. The Park contains several major ecosystems.
