Context paragraphs:
Grand Canyon Village Historic District: 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.

Yarlung Tsangpo Grand Canyon: The Yarlung Tsangpo Grand Canyon or Yarlung Zangbo Grand Canyon () or simply the Tsangpo Canyon, Brahmaputra Canyon or Tsangpo Gorge, along the Yarlung Tsangpo River in Tibet, China, is the deepest canyon in the world, and at 504.6 km (314 miles) is slightly longer than the Grand Canyon in the United States, making it one of the world's largest.  The Yarlung Tsangpo (Tibetan name for the upper course of the Brahmaputra) originates near Mount Kailash and runs east for about 1700 km, draining a northern section of the Himalayas before it enters the gorge just downstream of Pei, Tibet near the settlement of Zhibe.  The canyon has a length of about 150 miles (240 km) as the gorge bends around Mount Namcha Barwa (7782 m) and cuts its way through the eastern Himalayan range.  Its waters drop from about 2,900 m near Pei to about 1,500 m at the end of the Upper Gorge where the Po Tsangpo River enters.  The river continues through the Lower Gorge to the Indian border at an elevation of 660 m.  The river then enters Arunachal Pradesh and eventually becomes the Brahmaputra.

John Hance: 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.

Grand Canyon Inn and Campground: 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.

The design of the cabins and the redesign of the Inn building were undertaken by architect Gilbert Stanley Underwood.

Grand Canyon Depot: 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.

Toroweap Formation: The Middle Permian Toroweap Formation is a thin, darker geologic unit, between the brighter colored units of the Kaibab Limestone above, and Coconino Sandstone below.  It is a prominent unit in Grand Canyon, Arizona, USA, found through sections of the South Rim, Grand Canyon, and the North Rim, of the Kaibab Plateau; also the Kaibab's southeast extension to Cape Royal, the Walhalla Plateau.  The Colorado River of the Grand Canyon makes its excursion from due-south to due-west around the Walhalla Plateau, as it enters the east end of the Grand Canyon's interior, Granite Gorge.  The formation is also found in southeast Utah.
