Steamboat Mountain (Coconino County, Arizona)
Steamboat Mountain is a summit located in the Grand Canyon, in Coconino County, Arizona, Coconino County of northern Arizona, Southwestern United States, US. It is situated four miles northwest of Holy Grail Temple, and 2.5 miles west-southwest of Timp Point on the North Rim. George Wharton James described it as a "majestic butte", nearly encircled by Galloway and Saddle Canyons. Topographic relief is significant as it rises over above the Colorado River in three miles. According to the Köppen climate classification system, Steamboat Mountain is located in a Cold semi-arid climate zone, with precipitation Surface runoff, runoff draining west to the Colorado River via Tapeats Creek and Stone Creek. This feature's name was officially adopted in 1932 by the U.S. Board on Geographic Names. History In 1858, Lieutenant Joseph Christmas Ives, Joseph Ives led an expedition up the Colorado River, starting at the river's mouth and making it to the lower Grand Canyon. The mode of transpor ...

Powell Plateau (Arizona)
Powell Plateau, named for geologist and explorer John Wesley Powell, is a 7,661-foot-elevation plateau-summit located in western Grand Canyon, about 13 mi northwest of Grand Canyon Village in Coconino County, Arizona, Coconino County of northern Arizona, Southwestern United States, USA. Being a large plateau. (~300 acres, 0.47 mi2), the plateau causes a large west-northeast-north excursion of the west-flowing Colorado River, caused by the southwest arm of the plateau. There is a slightly-southeast trending arm, and the main plateau then trends north to higher elevations. The east side of Powell Plateau is drained by White Creek (Muav Canyon), and is traversed by the North Bass Trail. The high point prominence is at the plateau's north terminus, opposite Swamp Point, (North Rim). The high point at the southeast arm's terminus adjacent Dutton Point is 7,538 ft. The high point of the southwest arm is 6,883 ft. References External links {{commons catego ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaibab Limestone
The Kaibab Limestone is a resistant cliff-former, cliff-forming, Permian geologic formation that crops out across the U.S. states of northern Arizona, southern Utah, east central Nevada and southeast California. It is also known as the Kaibab Formation in Arizona, Nevada, and Utah. The Kaibab Limestone forms the rim of the Grand Canyon. In the Big Maria Mountains, California, the Kaibab Limestone is highly metamorphic, metamorphosed and known as the Kaibab Marble. Nomenclature The Kaibab Limestone was named by Darton in 1910 for the Kaibab Plateau, which is on the north side of Grand Canyon in Coconino County, Arizona. In his definition of the Kaibab Limestone formation, no type locality (geology), type locality was designated. He also designated the Kaibab Limestone as the upper formation of the Aubrey Group, a now-abandoned stratigraphic unit. In 1921, Bassler and Reeside revised Darton's work and defined the Harrisburg Member of the Kaibab Limestone.Bassler, H., and J. B. R ...

Permian
The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the sauropsids ( reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these drier conditions, rose to dominance in place of their am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Explorers Monument is a 4,572-foot-elevation (1,394 meter) summit located in the Grand Canyon, in Coconino County, Arizona, Coconino County of northern Arizona, Southwestern United States, US. It is situated 3.5 miles due west of Mount Huethawali, within a meander of the Colorado River. It towers over 2,400 feet (730 meters) directly above the river, providing Rafting, rafters a view of this landmark. Explorers Monument is topped by rock of the Pennsylvanian (geology), Pennsylvanian-Permian Supai Group which overlays cliff-forming Mississippian (geology), Mississippian Redwall Limestone, which in turn overlays Cambrian Tonto Group. According to the Köppen climate classification system, Explorers Monument is located in a cold semi-arid climate zone. History Explorers Monument was originally named "Marcos Monument" by George Wharton James because it adjoins Marcos Terrace, which is named for Marcos de Niza, a Franciscan friar and explorer. Subsequently, the United St ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Fitzgerald Beale
Edward Fitzgerald "Ned" Beale (February 4, 1822 – April 22, 1893) was a national figure in the 19th-century United States.

He fought in the United States-Mexican War, emerging as a hero of the Battle of San Pasqual in 1846. He achieved national fame in 1848 in carrying to the east the first gold samples from California, contributing to the gold rush. In the late 1850s, Beale surveyed and built Beale's Wagon Road, which many settlers used to move to the West, and which became part of Route 66 and the route for the Transcontinental railroad.

Almon Harris Thompson
Almon Harris Thompson (September 24, 1839 – July 31, 1906), also known as A. H. Thompson, was an American topographer, geologist, explorer, educator and Civil War veteran. Often called "The Professor" or simply "Prof", Thompson is perhaps best known for being second in command of John Wesley Powell's Second Geographical Expedition (1871–1875), a federally funded scientific expedition that retraced the route of Powell's original expedition in order to further explore and map the drainages and canyons of the Green and Colorado Rivers in what is now southern Utah and northern Arizona. Thompson's diary of the expedition was originally published in the Utah Historical Quarterly in 1939. Through his work on the Powell expeditions and later as a geographer at the U.S. Geological Survey, he was responsible for naming many geographic locations in the Western United States. Thompson is also known for being a founding member of the National Geographic Society. Early life and education ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

George Montague Wheeler (October 9, 1842 – May 3, 1905) was an American pioneering explorer and cartographer, leader of the Wheeler Survey, one of the major surveys of the western United States in the late nineteenth century. Wheeler was born in Hopkinton, Massachusetts, the son of John Wheeler and Miriam P. Daniels. He graduated from West Point in 1866, ranked sixth in his class, and was commissioned as a lieutenant in the US Army United States Army Corps of Engineers, Corps of Engineers.
