Hi. My name is Katrina, and I will tell you about the Grand Canyon. It is one of the natural wonders of the world. The Grand Canyon is in Arizona. It is a very big gorge of the Colorado River. It is about 1 mile deep, 4-18 miles wide, and about 217 miles long.

Some people like to go to the Grand Canyon since it is a natural wonder. In 1540, a Spanish explorer, Garcia Lopez de Cardenas, was the first European to see the canyon. A US explorer, John Wesley Powell, became the first person the lead a group of people through the bottom of the canyon in a boat.

In 1908, the Grand Canyon became a national monument. A big area was titled the Grand Canyon National Park. In 1975, the park got bigger to add areas like the Marble Canyon, Lake Mead, and parts of the Glen Canyon. Riding rafts and boats along the river at the bottom of the Grand Canyon are popular.
