The Mariana Trench is 1,580 miles (2,542 kilometers) long — more than five times the length of the Grand Canyon. However, the narrow trench averages only 43 miles (69 km) wide.

Called the Mariana Trench, the underwater canyon descends 35,827 feet (10,920 meters) — the Grand Canyon only averages about 4,000 feet (1,200 meters) in depth.

The Colorado River has been carving the Grand Canyon for a few million years now, such that the canyon floor is around 6000 feet lower in elevation than the surrounding area, at about 2400 feet above sea level.

Consider: The oceans are an average of 2.3 miles deep and cover 139.7 million square miles. The Grand Canyon covers 1904 square miles and has an average depth of 1 mile. So, there’s 321 million cubic miles of ocean to fit in 1,904 cubic miles of Grand Canyon.

We live along the South Rim of the Canyon at a 7000-foot elevation in the ponderosa pine forest. Most new employees will reside in dormitory style housing sharing a room with another employee.

The Havasupai Indians and the Hualapai Indians are two Native American tribes deeply embedded in the history and current culture of the Grand Canyon.

The Havasupai people (Havasupai: Havsuw’ Baaja) are an American Indian tribe who have lived in the Grand Canyon for at least the past 800 years. Throughout the 20th century, the tribe used the US judicial system to fight for the restoration of the land.

The Colorado River erodes soil, rock, and other materials, making the Grand Canyon deeper every day. The Grand Canyon’s walls have stripes of different colors. The stripes are layers of sediment that stacked on top of each other over millions of years. Each layer shows a different time in Earth’s history.

On the south side of the Canyon, the phone line left the South Rim developed area by Bright Angel Lodge, went down Pipe Creek, and crossed the Colorado River….

Angular unconformity also causes geologic tilting. Angular unconformity occurs when parallel strata of sedimentary rocks are deposited on layers that are tilted, perhaps as a result of erosion.

Grand Canyon National Park, where animals are protected, is part of the region. There is an abundance of elk and deer as a food source for wolves. The region is connected to where wolves now live in the Blue Range Wolf Recovery Areas. If allowed, wolves will disperse naturally to the Grand Canyon region.

Elk And Mule Deer The mule deer are amongst the most common mammals sighted in the Grand Canyon, especially in the South Rim of the Grand Canyon National Park.

The life and times of an unlikely resident of Grand Canyon-Parashant National Monument. No one had seen the alligator for years. Though alligators are native to wide swaths of the southeastern United States, their range doesn’t extend to the Arizona desert.

Mountain lions (Puma concolor) are the largest predators found in the Grand Canyon. There are 18 native South American, 25 native North American, and 40 English names for this species, and the most common are puma, cougar, panther, and catamount.

In Grand Canyon National Park, they most frequently live in the forests of the North and South Rims. Mountain lions have very large territories- their home range is usually around 150 square miles. This means that most mountain lions here live both in the Park and the surrounding Forest Service lands.

Fish native to Grand Canyon, from left to right: humpback chub, razorback sucker, bluehead sucker, flannelmouth sucker, speckled dace, and the three extirpated species: Colorado pikeminnow, roundtail chub and bonytail. Grand Canyon was once home to eight species of native fish.
