The Grand Canyon 1: A Sight Beyond Words
EDITOR'S NOTE: This year, the U.S. National Park Service turns 100. American’s 28th President, Woodrow Wilson, formed the National Park Service in 1916 to “protect the wild and wonderful landscapes” in the United States. President Ulysses Grant established Yellowstone National Park as the country’s first national park in 1872. Today, the National Park Service protects over 400 parks and historical sites from coast to coast. Every week, VOA Learning English will profile one of the sites within the National Park Service.
Our National Parks journey continues this week in one of the most popular and beautiful places in America: Grand Canyon National Park in the state of Arizona.
The Grand Canyon is one of the seven natural wonders of the world, and one of the largest canyons 2 on Earth. It stretches for 450 kilometers. Parts of the canyon are more than 30 kilometers wide and one kilometer deep.
Many writers have tried to describe the wonder of the Grand Canyon. They use words like mysterious, overpowering, and strange. But it is not possible to put human meaning to such a place. The Grand Canyon truly is beyond words.
"Is this your first time at the Grand Canyon?"
“Yes...."
And what do you think (of the Grand Canyon)? Do you have a few words to describe it?”
“Beautiful. Amazing."
"What do you think of the Grand Canyon?"
"Very huge. Very colorful.”
"Do you have some words to describe what you are seeing?"
“Magic. It’s so magic(al) when I see it at first look.”
A look back in time
The canyons of America’s Southwest are deep, ancient openings in the Earth. They look as if they formed as the earth split apart.
In reality, rivers formed these canyons.
Forty million years ago, the Colorado River began cutting through the area around the present-day Grand Canyon. The river carried dirt and pieces of stone that slowly ate away at the surrounding rock. It left a pathway of enormous rock openings. At the same time, forces deep within the Earth pushed up the surrounding land.
Rain, snow, ice, wind and plant roots rubbed away at the top of this new canyon. Below, the river continued to uncover more and more levels of ancient rock.
Some of the exposed rocks along the Grand Canyon’s walls are nearly 2 billion years old. They are among the oldest rocks on earth, with many levels of granite 3, schist, limestone 4 and sandstone.
Environment
The Grand Canyon measures 2,500 meters from the canyon floor to its highest point.
Because of its size, the weather at the top of the canyon is often much different from the bottom.
On some winter days, for example, you may find cold winds and snow at the top. But at the bottom of the canyon, you may find warm winds and flowers.
?The Grand Canyon is home to some 2,000 plant species. Some of these species can only be found in the park.
The Park is also home to more than 370 species of bird, 90 kinds of mammals and 40 kinds of reptiles 5.
Many of the birds spend the whole lives in the Grand Canyon. Others species depend of the Canyon for food and shelter during large migrations 6.
The Grand Canyon was named a Globally Important Bird Area in 2014 because of the role it plays in protecting many species of birds.
Humans in the Grand Canyon
Native American occupied the Grand Canyon 3,000 years ago. Bones, hair, feathers and the remains 7 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 700 years.
In 1869, American John Wesley Powell explored the Grand Canyon. He recorded much of what we know today about the area.?
Powell and his group traveled in four boats along the Colorado River. He and his group of explorers knew very little about getting over the fast, rocky waters of the Colorado River. In many places, boast could be turned over by giant waves.
Soon after they started their journey, Powell’s group lost some of its food and equipment. Three members decided 8 to leave the group. As they walked up and out of the Grand Canyon, they were killed by Native Americans.
The rest of Powell's group survived the journey. Starved and tired, Powell and his group reached the end of the canyon. They had traveled by boat down the Colorado for more than three months.
?John Wesley Powell’s reports and maps from the trip greatly increased interest in the Grand Canyon. But visitors did not begin to go there in large numbers until 1901. That year, a railway was built that reached the area.
Visiting the Grand Canyon
Five million people visit the Grand Canyon National Park every year. The first sight of the canyon can leave visitors speechless.
Depending on the time of day, the sun lights up the rock walls in red, orange, and golden colors. The bright colors are the result of minerals in the rock. Their appearance changes endlessly -- with the light, the time of year, and the weather.
At sunset, the canyon walls display fiery 9 red and gold hues 10. Then they take on softer colors of blue, purple, and green.
Most visitors walk along paths partway down the canyon. It takes several hours to walk to the bottom, and even longer to climb back up. Some visitors choose to ride mules 11 to the bottom of the canyon. Mules are strong, sturdy animals that look similar to horses.
Visitors can also explore the Grand Canyon in other ways. Hundreds of thousands of people see the canyon by air each year. They pay a helicopter or an airplane pilot to fly them above and around the canyon.
Thousands of people every year choose to explore the Grand Canyon by boat from the Colorado River. These trips last one to three weeks.
Most people who come to the Grand Canyon National Park visit an area known as the “South Rim 12.” That area has shuttle buses that take visitors to overlooks.
Fewer people see the canyon from the “North Rim.” The North Rim is less than 20 kilometers across the canyon from the South Rim, but visitors must drive more than 350 kilometers by car from the South Rim to access the North Rim.
Visitors can also see the Grand Canyon from a huge glass walkway called the Skywalk. The Skywalk is on the Hualapai Indian Reservation in the western part of the canyon. The Hualapai Indians built it to increase tourism at the reservation. It opened in 2007.
The Skywalk extends more than 20 meters from the canyon’s rim. It is suspended more than 1,200 meters above the bottom of the canyon, and is shaped like a giant horseshoe.
Many call the skywalk an engineering wonder. But others have criticized the skywalk and its development. They say it reduces the enjoyment 13 of nature in the Grand Canyon.
For visitors hoping to get a view of the entire Grand Canyon, they will have to travel well beyond the state of Arizona.
The only place to see the entire canyon at once is from outer space.
