A designated UNESCO World Heritage Site, Grand Canyon is famous for the rock coloration and formation that is unique to the site. This steep sided gorge has a width of 0.2-29 km and extends from the Grand Wash Cliffs to northern Arizona which is about 446 km. The deepest part of the canyon is situated at the center of the Grand Canyon National Park and has a depth of 90km. This section covers the length of the rivers from Lake Mead to Lake Powell.
Grand Canyon is composed of semi-arid land and consists of structural basins and raised plateaus that are typical to this region. There are also a number of steep-walled canyons caused by drainage systems that have deeply cut through the rocks. Despite knowing this, there are still parts of the history of this site that remains a mystery and is still the subject of many debates. Apparently, despite the information gathered about this site, the geologists and scientist still cannot arrive at a consensus for example, about the age of the Canyon. However, they cannot deny that this site is geologically significant. It is like a natural museum full of diverse fossil records, a wide variety of rock types, an outstanding record book of the past three to four geologic eras and a number of caves rich in biological, paleontological, archeological and geological information and resources.
