Question: The Expedition that fought the Tiguex war also was the same expedition that marked the first European sightings of the Grand Canyon and what other notable American landmark?
Context: The Grand Canyon of the Stikine is a 45-mile (72 km) stretch of the Stikine River in northern British Columbia, Canada.  It has been compared to the Grand Canyon of the Colorado.  The canyon is home to a large population of mountain goats and other wildlife.  Officially the canyon is described as unnavigable by any watercraft, however there have been numerous successful descents made by expert whitewater paddlers since the first attempt in 1981.  Since it was first attempted, the Grand Canyon of the Stikine has maintained a legendary reputation among whitewater experts as the 'Mt. Everest' of big water expedition whitewater boating against which all other navigable rivers are measured. Grand Canyon Village is a census-designated place (CDP) located on the South Rim of the Grand Canyon, in Coconino County, Arizona, in the United States.  Its population was 2,004 at the 2010 Census.  Located in Grand Canyon National Park, it is wholly focused on accommodating tourists visiting the canyon.  Its origins trace back to the railroad completed from Williams, Arizona, to the canyon's South Rim by the Santa Fe Railroad in 1901.  Many of the structures in use today date from that period.  The village contains numerous landmark buildings, and its historic core is a National Historic Landmark District, designated for its outstanding implementation of town design. 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. 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 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. 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. 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. Francisco Vázquez de Coronado y Luján (1510 – 22 September 1554) was a Spanish conquistador and explorer who led a large expedition from Mexico to present-day Kansas through parts of the southwestern United States between 1540 and 1542.  Vázquez de Coronado had hoped to reach the Cities of Cíbola, often referred to now as the mythical Seven Cities of Gold, which is a term not invented until American gold-rush days in the 1800s.  His expedition marked the first European sightings of the Grand Canyon and the Colorado River, among other landmarks.  His name is often Anglicized as "Vasquez de Coronado". The Tiguex War was the second named war – after the Battle of Mabila Oct 1540 – between Europeans and Native Americans in what is now the United States.  It was fought in the winter of 1540-41 by the expedition of Francisco Vázquez de Coronado against the twelve or thirteen pueblos of Tiwa Indians as well as other Puebloan tribes along both sides of the Rio Grande, north and south of present-day Bernalillo, New Mexico, in what was called the Tiguex Province.  The only book-length treatment of the Tiguex War is in the historical novel, Winter of the Metal People.
