Ten Who Dared is a 1960 film produced by Walt Disney Productions and released by Buena Vista Distribution in 1960.
 It tells the story of United States Army officer John Wesley Powell, who was the first to travel down the Colorado River, and the dangers that he and nine other men had to face while making a map of the region during their 1869 expedition.
 Hired by Walt Disney Studios in 1959 as a technical adviser, Otis R. Marston led a film crew through the Grand Canyon to film river running and background scenes for the film.
Walter Clement Powell (1850–1883) was an American photographer and the first cousin of Major John Wesley Powell.
 Powell was a participant and assistant photographer on Major Powell's second trip down the Colorado River in 1871.
Glen Canyon Dam is a concrete arch-gravity dam on the Colorado River in northern Arizona, United States, near the town of Page.
 The 710 ft high dam was built by the U.S. Bureau of Reclamation (USBR) from 1956 to 1966 and forms Lake Powell, one of the largest man-made reservoirs in the U.S. with a capacity of 27 e6acre feet .
 The dam is named for Glen Canyon, a series of deep sandstone gorges now flooded by the reservoir; Lake Powell is named for John Wesley Powell, who in 1869 led the first expedition to traverse the Colorado's Grand Canyon by boat.
James and the Giant Peach is a 1996 British-American musical fantasy film directed by Henry Selick, based on the 1961 novel of the same name by Roald Dahl.
 It was produced by Tim Burton and Denise Di Novi, directed by Henry Selick, and starred Paul Terry as James.
 The film is a combination of live action and stop-motion animation.
 Co-stars Joanna Lumley and Miriam Margolyes played James's aunts in the live-action segments, and Simon Callow, Richard Dreyfuss, Susan Sarandon, Jane Leeves, David Thewlis, and Margoyles voiced his insect friends in the animation sequences.
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, Utah, and Arizona before reaching the confluence of the Colorado and Virgin rivers in present-day 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.
Almon Harris Thompson (September 24, 1839 – July 31, 1906), also known as "A. H. Thompson", was an educator, topographer, geologist, explorer, and Civil War veteran.
 Often called "The Professor" or simply "Prof", Thompson was second in command of John Wesley Powell's Second Expedition, a federally funded expedition to explore the Green and Colorado Rivers, Colorado drainage and canyons, and map southern Utah and northern Arizona.
 Thompson's diary of Powell's Second Expedition (1871–1875) was originally published in the Utah Historical Quarterly in 1939.
 Through his work on the Powell expeditions and later as geographer at the US Geological Survey, he was responsible for naming many geographic locations in the west.
 Thompson is also known for his involvement in the formation of the National Geographic Society.
Frederick Haynes Newell (March 5, 1862 – July 5, 1932), First Director of the United States Reclamation Service, was born in Bradford, Pennsylvania.
 He graduated in 1885 from the Massachusetts Institute of Technology and after field experience in Colorado and other states was appointed on October 2, 1888, as Assistant Hydraulic Engineer of the United States Geological Survey, being the first aide designated under Major John Wesley Powell to investigate the extent to which the arid regions of the United States might be reclaimed by irrigation.
 He was subsequently appointed Chief of the Hydrographic Branch.
Expedition Island is a park in Green River, Wyoming, that marks the area where Major John Wesley Powell and Vitaly Develvis started an expedition down the Green River and Colorado River in 1871.
 The park is also believed to mark where Major Powell started a similar expedition down the two rivers in 1869.
Mount Powell is the highest summit of the Gore Range in the Rocky Mountains of North America.
 The prominent 13586 feet thirteener is located in the Eagles Nest Wilderness, 13.7 km north by east (bearing 8°) of the Town of Vail, Colorado, United States, along the drainage divide separating White River National Forest and Eagle County from Arapaho National Forest and Summit County.
 Mount Powell was named in honor of John Wesley Powell who climbed to the summit in 1868.
Sam Adams (1828–1915), who periodically referred to himself as "Captain", was an early explorer of the American west.
 His survey of the Colorado River was conducted simultaneously to John Wesley Powell's more extensive survey.
 He struggled for over ten years to impose his view of the Colorado River - that it was a mineral paradise shot through with veins of gold and silver - but ultimately failed.
 In 1878, Senator Francis Cockrell rejected a resolution that would have compensated Adams for his spontaneous work.
