Grand Canyon

The Grand Canyon (Hopi: Ongtupqa; Yavapai: Wi:kaʼi:la, Spanish: Gran Cañón) is a steep-sided canyon carved by the Colorado River in the U.S. state of Arizona. It is contained within and managed by Grand Canyon National Park, the Kaibab National Forest, Grand Canyon-Parashant National Monument, the Hualapai Tribal Nation, the Havasupai people and the Navajo Nation. President Theodore Roosevelt was a major proponent of preservation of the Grand Canyon area, and visited it on numerous occasions to hunt and enjoy the scenery.

The Grand Canyon is 277 miles (446 km) long, up to 18 miles (29 km) wide and attains a depth of over a mile (6,093 feet or 1,857 meters).[1] Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted. While the specifics are open to debate, the best evidence suggests that the river established its course through the canyon at least 17 million years ago, and subsequent erosion formed the canyon's present-day configuration.

For thousands of years, the area has been continuously inhabited by Native Americans, including the Pueblos who considered it a holy site, and made pilgrimages to it. The first European known to have viewed the Grand Canyon was García López de Cárdenas from Spain, who arrived in 1540.

Grand Canyon in "Down in the Bottomlands"
There was a notable geological depression in the Empire of Stekia. It was the largest such feature in that continent, but paled in comparison to the Bottomlands.
