It is considered one of the 7 wonders of the world and continually gathers an audiance of more than four million people anually. The Grand Canyon became a national park in 1919. President Woodrow Wilson signs the Grand Canyon Park bill, February 26th after both the house and the senate passed the bill.
When you gaze down thousands of feet, you see what appears to be a blue ribbon. That blue ribbon just happens to be the Colorado River. Recently, in 2007, they added a sky walk. This skywalk hangs over a side of the Grand Canyon. It is a little over four thousand feet from the bottom with the bottom being glass. However, the Grand Canyon was not always like this. It was once a flat piece of land that was eroded away by the river. Now, thousand of years later, it has become a place everyone should see before they die.

Here are a few pictures :)
