The Grand Canyon is a steep-sided canyon carved by the Colorado River in Arizona, United States. The Grand Canyon is 277 miles (446 km) long, up to 18 miles (29 km) wide and attains a depth of over a mile.
A canyon, gorge or chasm, is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering.
Thomas Moran was an American painter and printmaker of the Hudson River School in New York whose work often featured the Rocky Mountains. Moran and his family, wife Mary Nimmo Moran and daughter Ruth took residence in New York where he obtained work as an artist. He was a younger brother of the noted marine artist Edward Moran, with whom he shared a studio. A talented illustrator and exquisite colorist, Thomas Moran was hired as an illustrator at Scribner's Monthly. During the late 1860s, he was appointed the chief illustrator for the magazine, a position that helped him launch his career as one of the premier painters of the American landscape, in particular, the American West.
The Grand Canyon of the Yellowstone is the first large canyon on the Yellowstone River downstream from Yellowstone Falls in Yellowstone National Park in Wyoming. The canyon is approximately 24 miles (39 km) long, between 800 and 1,200 ft deep and from 0.25 to 0.75 mi wide.
Rocky Nelson, an Arizona entrepreneur, formed Arizona Airways in 1942, using Douglas DC-3 aircraft to fly passengers from Sky Harbor International Airport in Phoenix, to other, nearby destinations, including Prescott Municipal Airport in Prescott, Arizona, and Tucson International Airport in Tucson, Arizona.
Astronomy Picture of the Day (APOD) is a website provided by NASA and Michigan Technological University (MTU). It reads: "Each day a different image or photograph of our universe is featured, along with a brief explanation written by a professional astronomer." The photograph does not necessarily correspond to a celestial event on the exact day that it is displayed, and images are sometimes repeated. These often relate to current events in astronomy and space exploration. The text has several hyperlinks to more pictures and websites for more information. The images are either visible spectrum photographs, images taken at non-visible wavelengths and displayed in false color, video footage, animations, artist's conceptions, or micrographs that relate to space or cosmology.
U.S. Route 89 is a north–south United States Numbered Highway with two sections, and one former section. The southern section runs for 848 miles (1,365 km) from Flagstaff, Arizona, to the southern entrance of Yellowstone National Park. The northern section runs for 404 miles (650 km) from the northern entrance of Yellowstone National Park in Montana, ending at the Canadian border. Unnumbered roads through Yellowstone connect the two sections. Before 1992, US 89 was a Canada–Mexico, border-to-border highway that ended at Nogales, Arizona, on its southern end.
U.S. Route 191 is a spur of U.S. Route 91 that has two segments. The southern segment runs for 1,102 miles (1,773 km) from Douglas, Arizona on the Mexican border to the southern part of Yellowstone National Park. The northern segment runs for 442 miles (711 km) from the northern part of Yellowstone National Park to Loring, Montana, at the Canada–US border. Unnumbered roads within Yellowstone National Park connect the two segments. The highway passes through the states of Arizona, Utah, Wyoming, and Montana.
The known human history of the Grand Canyon area stretches back 10,500 years, when the first evidence of human presence in the area is found. Native Americans have inhabited the Grand Canyon and the area now covered by Grand Canyon National Park for at least the last 4,000 of those years. Ancestral Pueblo peoples, first as the Basketmaker culture and later as the more familiar Pueblo people, developed from the Desert Culture as they became less nomadic and more dependent on agriculture. A similar culture, the Cochimi also lived in the canyon area. Drought in the late 13th century likely caused both groups to move on. Other people followed, including the Paiute, Cerbat, and the Navajo, only to be later forced onto reservations by the United States Government.

Tower Fall is a waterfall on Tower Creek in the northeastern region of Yellowstone National Park, in the U.S. state of Wyoming. Approximately 1,000 yards (910 m) upstream from the creek's confluence with the Yellowstone River, the fall plunges 132 feet (40 m). Its name comes from the rock pinnacles at the top of the fall. Tower Creek and Tower Fall are located approximately three miles south of Roosevelt Junction on the Tower-Canyon road.
The Coprates quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Coprates quadrangle is also referred to as MC-18. The Coprates quadrangle contains parts of many of the old classical regions of Mars: Sinai Planum, Solis Planum, Thaumasia Planum, Lunae Planum, Noachis Terra, and Xanthe Terra.
Ius Chasma is a large canyon in the Coprates quadrangle of Mars at 7° south latitude and 85.8° west longitude. It is about 938 km long and was named after a classical albedo feature name.
Grand Canyon Scenic Airlines is an American regional airline based in Paradise, Nevada, United States. It operates sightseeing flights from Boulder City Municipal Airport in Boulder City, Nevada. Scenic has been owned by Grand Canyon Airlines since 2008.
The Vishnu Basement Rocks is the name recommended for all Early Proterozoic crystalline rocks exposed in the Grand Canyon region. They form the crystalline basement rocks that underlie the Bass Limestone of the Unkar Group of the Grand Canyon Supergroup and the Tapeats Sandstone of the Tonto Group. These basement rocks have also been called either the Vishnu Complex or Vishnu Metamorphic Complex. These Early Proterozoic crystalline rocks consist of metamorphic rocks that are collectively known as the Granite Gorge Metamorphic Suite; sections of the Vishnu Basement Rocks contain Early Paleoproterozoic granite, granitic pegmatite, aplite, and granodiorite that have intruded these metamorphic rocks, and also, intrusive Early Paleoproterozoic ultramafic rocks.
Tower of Set is a 6,012-foot-elevation (1,832-meter) summit located in the Grand Canyon, in Coconino County of Arizona, US. This butte is situated four miles north of Hopi Point overlook on the canyon's South Rim, two miles southeast of Tower of Ra, and three miles south-southwest of Shiva Temple, where it towers 3,600 feet above the Colorado River. Tower of Set was originally named Temple of Sett in 1879 by Thomas Moran, for the Egyptian deity of war, Set, because a niche worn into its wall evoked temples in the valley of the Nile. Another source states it was named by George Wharton James, in keeping with Clarence Dutton's tradition of naming geographical features in the Grand Canyon after mythological deities. This mountain's name was officially adopted in 1906 by the U.S. Board on Geographic Names. In 1919, Harriet Williams Russell Strong proposed connecting Hopi Point and Tower of Set across the river via an aerial tramway, an idea that never came to fruition. The first ascent was made in November 1977 by Bruce Grubbs and Jim Haggart. According to the Köppen climate classification system, Tower of Set is located in a cold semi-arid climate zone.
Dox Castle is a 4,780-foot-elevation (1,460-meter) summit located in the Grand Canyon, in Coconino County of northern Arizona, US. It is situated four miles north-northeast of Havasupai Point, two miles northwest of Evans Butte, and 2.5 miles southwest of Holy Grail Temple, where it towers 2,500 feet above the Colorado River.
