The Grand Canyon, in Arizona which follows the Colorado River is a large gorge carved by said river and is millions of years old. The canyon is very large, and was made one of the first national parks in the United States of America by the president Franklin Delano Roosevelt, but was also previously a target of conservation by the previous Theodore Roosevelt some two decades earlier.

The Grand Canyon attracts more than five million tourists a year who take hiking treks down into the canyon along with rafting in the Colorado River. The canyon itself is dated at being over six million years old and well over 270 miles long. The rocks exposed by the Grand Canyon range from 2 billion years old to 230 million years old, and are easily seen in the layers of rocks exposed by the ever-cutting Colorado River. The only threat to this location is air pollution and increased human presence, but due to its vast size and with proper human control littering is the most pervasive problem.
