Desert View Watchtower, also known as the Indian Watchtower at Desert View, is a 70 ft -high stone building located on the South Rim of the Grand Canyon within Grand Canyon National Park in Arizona, United States.
 The tower is located at Desert View, more than 20 mi to the east of the main developed area at Grand Canyon Village, toward the east entrance to the park.
 The four-story structure, completed in 1932, was designed by American architect Mary Colter, an employee of the Fred Harvey Company who also created and designed many other buildings in the Grand Canyon vicinity including Hermit's Rest and the Lookout Studio.
 The interior contains murals by Fred Kabotie.
Otis Reed "Dock" Marston (February 11, 1894 – August 30, 1979) was an American author, 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.
Grand Canyon: A Different View is a 2003 book edited by Tom Vail.
 The book features a series of photographs of the Grand Canyon illustrating 20 essays by creationists Steve Austin, John Baumgardner, Duane Gish, Ken Ham, Russell Humphreys, Henry Morris, John D. Morris, Andrew A. Snelling, Larry Vardiman, John Whitcomb, and Kurt Wise.
 It presents the Young Earth creationist perspective that the canyon is no more than a few thousand years old and was formed by the Global Flood or Noachian flood of the Bible.
Hopi House is located on the South Rim of the Grand Canyon, within Grand Canyon National Park in the U.S. state of Arizona.
 Built in 1904 as concessioner facilities at the South Rim were being developed, it is the first of eight projects at the Grand Canyon that were designed by architect Mary Colter, along with Bright Angel Lodge, Hermit's Rest, Lookout Studio, Phantom Ranch, Desert View Watchtower, Colter Hall and Victor Hall, (the latter two being employee dormitories).
 Hopi House was built by the Fred Harvey Company as a market for Native American crafts, made by artisans on the site.
 The Hopi, as the historic inhabitants of the area, were chosen as the featured artisans, and the building was designed to closely resemble a traditional Hopi pueblo.
 Hopi House opened on January 1, 1905, two weeks before the El Tovar Hotel, located just to the west, was opened.
The known 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 Cinchona, 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.
Kenneth Alfred Ham (born 20 October 1951) is an Australian Christian fundamentalist and young Earth creationist living in the United States.
 He is president of Answers in Genesis (AiG), a Creationist apologetics organization that operates the Creation Museum and the Ark Encounter.
The geology of the Grand Canyon area includes one of the most complete and studied sequences of rock on Earth.
 The nearly 40 major sedimentary rock layers exposed in the Grand Canyon and in the Grand Canyon National Park area range in age from about 200 million to nearly 2 billion years old.
 Most were deposited in warm, shallow seas and near ancient, long-gone sea shores in western North America.
 Both marine and terrestrial sediments are represented, including fossilized sand dunes from an extinct desert.
 There are at least 14 known unconformities in the geologic record found in the Grand Canyon.
Lookout Studio, known also as The Lookout, is a stone building located on the South Rim of the Grand Canyon, within Grand Canyon National Park in Arizona.
 It is part of the Grand Canyon Village Historic District, and is part of the Mary Jane Colter Buildings National Historic Landmark.
 It currently operates as a gift shop and observation station for visitors, with telescopes on its outdoor terrace.
 Lookout Studio was constructed by the Santa Fe Railway in 1914 and was established as a photography studio to compete with Kolb Studio.
 It is one of six buildings at the Grand Canyon that were designed by architect Mary Colter, along with Bright Angel Lodge, Hermit's Rest, Hopi House, Phantom Ranch, and Desert View Watchtower.
 Lookout Studio employs her signature rustic style of using jagged native rocks to imitate indigenous structures of the region and to blend in with the environment.
The Grand Canyon National Park is a U.S. National Park located in the state of Arizona.
 The Park encompasses the Grand Canyon and the surrounding rim areas.
 The Park maintains an intricate trail system both above and below the rims of the canyon.
 To properly maintain and supervise the many trails and campgrounds in the backcountry of the Grand Canyon, Park implemented a system of zoning the different areas of the canyon and the surrounding rim area into backcountry "use areas," designated by a two-letter, one-number code system.
Palo Duro Canyon is a canyon system of the Caprock Escarpment located in the Texas Panhandle near the cities of Amarillo and Canyon.
 As the second-largest canyon in the United States, it is roughly 120 mi long and has an average width of 6 mi , but reaches a width of 20 mi at places.
 Its depth is around 820 ft , but in some locations, it can increase up to 1000 ft .
 Palo Duro Canyon (from the Spanish meaning "hard wood") has been named "The Grand Canyon of Texas" both for its size and for its dramatic geological features, including the multicolored layers of rock and steep mesa walls similar to those in the Grand Canyon.
