The Grand Canyon is a deep indention in the Earth's surface, also known as a chasm which is 277 miles long and 18 miles wide. It took 3-6 million years to form the Grand Canyon and it is still being changed by erosion. The Grand Canyon covers 1,218,375 acres. Erosion of the Colorado River is shaping the Grand Canyon as we speak. Other factors changing the shape of the Grand Canyon over time are rain, snow, heat, frost, and wind. The canyon shows traces of the Paleo-Indians. Rock art and artifacts show many traces of the Paleo people. The first Europeans to explore the canyon were the party of Francisco Vasquez de Coronado monumental southwest entrada. His group of explores were first to see the canyon. The Grand Canyon is millions of years old so it is hard to tell who exactly discovered it first. Throughout the Grand Canyon there are specific places such as the North Rim, the South Rim, the Havasupai Indian Reservation, the Hualapai Indian Reservation, and the Tuweep.


Some Economic Impact Analysis (EIA) of outdoors have studied the impact of the Grand Canyon to the area surrounding it. Tourism affects the economy because of the many people visiting the Grand Canyon and spending their money there. Outdoor activities not only are "green" activities by being good for the environment but they are also generating resources in beneficial socioeconomic impacts of the communities. The state of Arizona is highly dependent on the tourism and recreational activities the Grand Canyon Resort attracts to the area. According to IMPLAN more than 20,000 people rafted on the Colorado River that is throughout the Grand Canyon National Park in 2001. This popularity had an outcome of $21,100,000 benefiting the Grand Canyon. Considering the economy tourism has a great impact on the economy of the state of Arizona regardless. In 2008 Arizona had 37.4 million tourist and travelers resulting in billions of dollars. In 2007 traveling was the top industry bringing in money into Arizona. Obviously the Grand Canyon is extremely important in generating careers and revenue. The Grand Canyon supports almost 170,000 jobs and generates about $5 million dollars.

Geologist have predicted the natural water resources will be implicated because of the extreame climate change and drought. They will try to find a way to manage this problem to attempt to save the future of the Grand Canyon water resources.

The Talampaya Canyon in Argentina is a remarkable canyon similar to the Grand Canyon; it has formed by erosion just as well as the Grand Canyon. The walls of the canyon are as high as 143 meters. This is tiny compared to the Grand Canyon but still is similar in many ways.

Mountains are ever changing because of erosion; this causes many things to change the appearance of the mountains and rock. So this chasm will not always be a major landmark in the United States. Mountains begin as formations of sediments. These formations will eventually be changed by erosion which is also apart of the rock cycle. These rocks are lifted up and "distorted" forming mountain ranges. After millions of years these mountains will be changed and no longer be the mountains we know them as. We do now.
