The Grand Canyon is a massive geological feature in the American state of Arizona. Due to efforts of conservationists, the region became a Forest Preserve in 1893 and was protected from unrestricted hunting and logging. Later, because of its popularity, the region was made into Grand Canyon National Park. The park covers over 1.2 million acres of land, and hosts nearly 5 million visitors annually.

The Grand Canyon provides a tremendous example of the results of large-scale erosion, which is important in developing an understanding of the mechanisms likely to have been active in the Biblical global flood. For many years creation scientists have taught that the Grand Canyon was formed rapidly when a large lake on the northern border of the Colorado Plateau broke through its natural dam. In contrast, secular science has taught that the Colorado river eroded the canyon gradually over millions of years based on the uniformitarian assumptions. However, researchers have recently determined that the Grand Canyon is a geologic infant in comparison to previous estimates, and it has been concluded that indeed much of the canyon was eroded rapidly as a result of dam failure.
