Native American Indians occupied the Grand Canyon three thousand years ago. Evidence of their existence has been found in more than two thousand five hundred places so far. Bones, hair, feathers, even the remains of plants have been found in deep, dry caves high in the rock walls.
The Hopi, the Paiute, the Navajo and other Native American tribes have all been in the area for at least seven centuries. However, much of what we know today about the Grand Canyon was recorded by John Wesley Powell. In eighteen sixty-nine, he became the first white American to explore much of the canyon.
John Wesley Powell and his group traveled in four boats. They knew very little about getting over the rapid, rocky waters of the Colorado River. In many areas of fast-flowing water, a boat could be turned over by a wave as high as a house.
Soon after starting, Powell's group lost some of its food and equipment. Then three members of the group left. As they walked up and out of the canyon, they were killed by Indians. The rest of the group was lucky to survive. Starving and tired, they reached the end of the canyon. They had traveled on the Colorado River for more than three months. John Wesley Powell's reports and maps from the trip made him famous. They also greatly increased interest in the Grand Canyon. But visitors did not begin to go to there in large numbers until nineteen-oh-one. That was when a railroad reached the area.
Today, the Grand Canyon is known as one of the seven wonders of the natural world. About five million people visit the canyon each year. Most visitors walk along paths part way down into the canyon. It takes several hours to walk to the bottom. It takes two times as long to get back up. Some visitors ride mules to the bottom and back. The mules are strong animals that look like horses. They are known for their ability to walk slowly and safely on the paths.
America's National Park Service is responsible for protecting the Grand Canyon from the effects of so many visitors. All waste material must be carried out of the canyon. All rocks, historical objects, plants, and wildlife must be left untouched. As the National Park Service tells visitors: "Take only photographs. Leave only footprints. "
There are several other ways to visit the Grand Canyon. Hundreds of thousands of people see the canyon by air each year. They pay a helicopter or airplane pilot to fly them above and around the canyon.
About twenty thousand people a year see the Grand Canyon from the Colorado River itself. They ride boats over the rapid, rocky water. These trips last from one week to three weeks.
