The Grand Canyon Inn and Campground, also known as the North Rim Inn, were built by the William W. Wylie and the Utah Parks Company as inexpensive tourist accommodations on the North Rim of the Grand Canyon, in Grand Canyon National Park.
 Intended to complement the more expensive Grand Canyon Lodge, the cabins and Inn were located near Bright Angel Point, but father back than their more expensive counterparts, near the Grand Canyon North Rim Headquarters.
 The design of the cabins and the redesign of the Inn building were undertaken by architect Gilbert Stanley Underwood.
Duane Tolbert Gish (February 17, 1921 – March 5, 2013) was an American biochemist and a prominent member of the creationist movement.
 A Young Earth creationist, Gish was a former vice-president of the Institute for Creation Research (ICR) and the author of numerous publications about creation science.
 Gish was called "creationism's T. H. Huxley" for the way he "relished the confrontations" of formal debates with prominent evolutionary biologists, usually held on university campuses.
 A creationist publication noted in his obituary that "it was perhaps his personal presentation that carried the day.
 In short, the audiences liked him."
Grand Canyon Village Historic District comprises the historic center of Grand Canyon Village, on the South Rim of the Grand Canyon in Grand Canyon National Park, Arizona.
 The district includes numerous landmark park structures, many of which are National Historic Landmarks themselves, or are listed on the National Register of Historic Places.
 The town design as a whole is also significant for its attention to integration with the Grand Canyon landscape, its incorporation of National Park Service Rustic design elements, and for the idiosyncratic design of park concessioner structures such as the El Tovar Hotel.
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.
John Hance (1840 – January 8, 1919) is thought to be the first non-Native American resident of the Grand Canyon, US.
 He opened the first tourist trail in the canyon in the late nineteenth century.
 He started giving tours of the canyon after his attempts at mining asbestos failed, largely due to the expense of removing the asbestos from the canyon.
 "Captain" John Hance was said to be one of the Grand Canyon's most colorful characters, and it had been declared by one early visitor that "To see the canyon only and not to see Captain John Hance, is to miss half the show."
 Hance delighted in telling canyon stories to visitors, favoring the whopper of a tale over mere facts.
 With a straight face, Hance told travelers how he had dug the canyon himself, piling the excavated earth down near Flagstaff (a dirt pile now known as the San Francisco Peaks).
 Despite such questionable claims, Hance left a lasting legacy at the Grand Canyon, dying in 1919, the year the Grand Canyon became a National Park.
 Hance was the first person buried in what would become the Grand Canyon Pioneer Cemetery.
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.
Grand Canyon Depot, also known as Grand Canyon Railroad Station, was constructed in 1909-10 for the Atchison, Topeka and Santa Fe Railway at the South Rim of the Grand Canyon, in what is now Grand Canyon National Park.
 It is one of three remaining railroad depots in the United States built with logs as the primary structure material.
 The station is within 100 m of the rim of the canyon, opposite the El Tovar Hotel, also built by the railroad.
 The depot is designated a National Historic Landmark.
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.
