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.
John Wesley Powell was an American geologist, U.S. Army soldier, explorer of the American West, professor at Illinois Wesleyan University, and director of major scientific and cultural institutions. He is famous for his 1869 geographic expedition, a three-month river trip down the Green and Colorado rivers, including the first official U.S. government-sponsored passage through the Grand Canyon.
The Little Colorado River is a tributary of the Colorado River in the U.S. state of Arizona, providing the principal drainage from the Painted Desert region. Together with its major tributary, the Puerco River, it drains an area of about 26,500 square miles (69,000 km2) in eastern Arizona and western New Mexico. Although it stretches almost 340 miles (550 km), only the headwaters and the lowermost reaches flow year-round. Between St. Johns and Cameron, most of the river is a wide, braided wash, only containing water after heavy snowmelt or flash flooding.
The Green River, located in the western United States, is the chief tributary of the Colorado River. The watershed of the river, known as the Green River Basin, covers parts of the U.S. states of Wyoming, Utah, and Colorado. The Green River is 730 miles (1,170 km) long, beginning in the Wind River Mountains of Wyoming and flowing through Wyoming and Utah for most of its course, except for a short segment of 40 miles (64 km) in western Colorado. Much of the route traverses the arid Colorado Plateau, where the river has carved some of the most spectacular canyons in the United States. The Green is slightly smaller than Colorado when the two rivers merge but typically carries a larger load of silt. The average yearly mean flow of the river at Green River, Utah is 6,121 cubic feet (173.3 m3) per second.
Clyde Martin Litton was a Grand Canyon river runner and a longtime conservationist, best known as a staunch opponent of the construction of Glen Canyon Dam and other dams on the Colorado River.
Glen and Bessie Hyde were newlyweds who disappeared while attempting to run the rapids of the Colorado River through Grand Canyon, Arizona in 1928. Had the couple succeeded, Bessie Hyde would have been the first woman known to accomplish this feat.
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.
Glen Canyon is a natural canyon carved by a 169.6-mile (272.9 km) length of the Colorado River, mostly in southeastern and south-central Utah, in the United States. Glen Canyon starts where Narrow Canyon ends, at the confluence of the Colorado River and the Dirty Devil River. A small part of the lower end of Glen Canyon extends into northern Arizona and terminates at Lee's Ferry, near the Vermilion Cliffs. Like the Grand Canyon farther downstream, Glen Canyon is part of the immense system of canyons carved by the Colorado River and its tributaries.
The Powell Geographic Expedition of 1869, led by American naturalist John Wesley Powell, was the first thorough cartographic and scientific investigation of long segments of the Green and Colorado rivers in the southwestern United States, including the first recorded passage of white men through the entirety of the Grand Canyon. The expedition, which lasted approximately three months during the summer of 1869, embarked from Green River Station, Wyoming Territory and traveled downstream through parts of the present-day states of Colorado and Utah before reaching the confluence of the Colorado and Virgin rivers in present-day Arizona and Nevada. Despite a series of hardships, including losses of boats and supplies, near-drownings, and the eventual departures of several crew members, the voyage produced the first detailed descriptions of much of the previously unexplored canyon country of the Colorado Plateau.
Wrong Again is a 1929 American two-reel silent comedy film directed by Leo McCarey and starring Laurel and Hardy. It was filmed in October and November 1928, and released February 23, 1929, by Metro-Goldwyn-Mayer. Although a silent film, it was released with a synchronized music and sound-effects track in theaters equipped for sound.
Lewis Ransome Freeman was an American explorer, journalist and war correspondent who wrote over twenty books chronicling his many travels, as well as numerous articles.
Stanley Davis Jones was an American songwriter and actor, primarily writing Western music. He is best remembered for writing "Ghost Riders in the Sky".
Haldane "Buzz" Holmstrom (1909–1946) was a pioneer of running the Colorado River through the Grand Canyon. He was the first person to float all the way from Green River, Wyoming to Boulder Dam solo. He built his own rowboats, often of his own design, to run whitewater rivers.
Norman D. Nevills was a pioneer of commercial river-running in the American Southwest, particularly the Colorado River through the Grand Canyon. He led trips including Dr. Elzada Clover and Lois Jotter, the first two women to successfully float the Grand Canyon, and Barry Goldwater.
Albert A. "Bert" Loper was a pioneer of the sport of whitewater river-running in the American Southwest, particularly the Colorado River and its tributaries. He, along with many of the noted boatmen of his era, including Charles Russell, Julius Stone, Ellsworth Kolb, and others, were among the first people to navigate the Colorado River before the construction of Glen Canyon Dam and Navajo Dam.
Facing Your Danger is a 1946 American short film. The cameraman was amateur filmmaker Edwin E. Olsen. Using a Cine-Kodak and 16mm Kodachrome film, Olsen shot the film in 1942 on a Grand Canyon river trip conducted by Norman Nevills. Another amateur cameraman on the trip was Otis R. Marston. When Olsen ran out of film, Marston, who had brought 6,000 feet of Kodachrome magazines, provided Olsen with what he needed. Olsen edited the film and sold it to Warner Brothers in 1946. Lee Anthony and Gordon Hollingshead collaborated to re-edit and shorten the film to a one reel for theater release.
Cataract Canyon is a 46-mile-long (74 km) canyon of the Colorado River located within Canyonlands National Park and Glen Canyon National Recreation Area in southern Utah. It begins at Colorado's confluence with the Green River, and its downstream terminus is the confluence with the Dirty Devil River. The lower half of the canyon is submerged beneath Lake Powell when the lake is at its normal high water elevation of 3,700 feet (1,100 m).
The Exploration of the Colorado River and Its Canyons by John Wesley Powell is a classic of American exploration literature. It is about the Powell Geographic Expedition of 1869 which was the first trip down the Colorado River by boat, including the first trip through the Grand Canyon.
Otis Reed "Dock" Marston was an American writer, historian and Grand Canyon river runner who participated in a large number of river-running firsts. Marston was the eighty-third person to successfully complete the water transit of the Grand Canyon. He spent the last thirty years of his life writing his magnum opus on the history of the first 100 Grand Canyon river runners. In researching his book, he amassed a vast collection of material on early river runners in the American Southwest, especially runners of the Green and Colorado Rivers. His collection is housed in the Huntington Library in San Marino, California.
John Colton Sumner (1840–1907) was an American explorer who took part in the Powell Geographic Expedition of 1869. An experienced marksman and boatman, he was chosen by John Wesley Powell to lead the first boat of the expedition. He eventually had a falling out with Powell over differences in personality, and was troubled through the rest of his life over the disappearance and deaths of three other men in the expedition. His remorse and resentment became so great that, in 1902, he castrated himself.
