Dana Butte
Dana Butte is a prominence, (named for geologist and volcanologist James Dwight Dana), adjacent the course of the Colorado River, in the Grand Canyon and sits on the south side of Granite Gorge. The butte is roughly north-northwest of Grand Canyon Village of the central Grand Canyon, and lies about due north of Pima Point (South Rim). The butte lies at the end of a higher elevation bright-red, very narrow Supai Group ridgeline, and the spire of Dana Butte sits on the cliff-former Redwall Limestone that creates not only massive cliffs, but platforms that support younger rock units above. Dana Butte's prominence spire is dull gray, sitting on gray debris on the platform, and is composed of weathered Supai Group Manakacha Formation, also a cliff-former rock. Dana Butte drains west into the Salt Creek (Grand Canyon) drainage, and east into the adjacent canyon of the terminus of Salt Creek.

Grand Canyon
The Grand Canyon (, yuf-x-yav, Wi:kaʼi:la, , Southern Paiute language: Paxa’uipi, ) is a steep-sided canyon carved by the Colorado River in Arizona, United States. The Grand Canyon is long, up to wide and attains a depth of over a mile (). The canyon and adjacent rim are contained within Grand Canyon National Park, the Kaibab National Forest, Grand Canyon–Parashant National Monument, the Hualapai Indian Reservation, the Havasupai Indian Reservation and the Navajo Nation. President Theodore Roosevelt was a major proponent of the preservation of the Grand Canyon area and visited it on numerous occasions to hunt and enjoy the scenery. Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted.

Geologist
A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other terrestrial planets, as well as the processes that shape them. Geologists usually study geology, earth science, or geophysics, although backgrounds in physics, chemistry, biology, and other sciences are also useful. Field research (field work) is an important component of geology, although many subdisciplines incorporate laboratory and digitalized work. Geologists can be classified in a larger group of scientists, called geoscientists. Geologists work in the energy and mining sectors searching for natural resources such as petroleum, natural gas, precious and base metals. They are also in the forefront of preventing and mitigating damage from natural hazards and disasters such as earthquakes, volcanoes, tsunamis and landslides. Their studies are used to warn the general public of the occurrence of these events. Geologists are also important contributors to climate ch ...

Grand Canyon National Park
Grand Canyon National Park, located in northwestern Arizona, is the 15th site in the United States to have been named as a national park. The park's central feature is the Grand Canyon, a gorge of the Colorado River, which is often considered one of the Wonders of the World. The park, which covers of unincorporated area in Coconino and Mohave counties, received more than six million recreational visitors in 2017, which is the second highest count of all American national parks after Great Smoky Mountains National Park. The Grand Canyon was designated a World Heritage Site by UNESCO in 1979. The park celebrated its 100th anniversary on February 26, 2019. History The Grand Canyon became well known to Americans in the 1880s after railroads were built and pioneers developed infrastructure and early tourism. In 1903, President Theodore Roosevelt visited the site and said, The Grand Canyon fills me with awe. It is beyond comparison—beyond description; absolutely unparalleled ...

Buttes Of Arizona
__NOTOC__ In geomorphology, a butte () is an isolated hill with steep, often vertical sides and a small, relatively flat top; buttes are smaller landforms than mesas, plateaus, and tablelands. The word ''butte'' comes from a French word meaning knoll (but of any size); its use is prevalent in the Western United States, including the southwest where ''mesa'' (Spanish for "table") is used for the larger landform. Due to their distinctive shapes, buttes are frequently landmarks in plains and mountainous areas. To differentiate the two landforms, geographers use the rule of thumb that a mesa has a top that is wider than its height, while a butte has a top that is narrower than its height. Formation Buttes form by weathering and erosion when hard caprock overlies a layer of less resistant rock that is eventually worn away. The harder rock on top of the butte resists erosion. The caprock provides protection for the less resistant rock below from wind abrasion which leaves it standin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Battleship (Grand Canyon)
The Battleship is a -elevation summit located in central Grand Canyon, in Coconino County of northern Arizona, United States. The ridgeline, Battleship landform forms part of the western border of Garden Creek Canyon, which contains the Bright Angel Trail down to the Colorado River, and across it to Phantom Ranch. The east border of Garden Creek Canyon is the South Rim, with the overlooks of Grandeur Point and Yavapai Point. The Battleship is northwest of Yavapai Point, 1.5 miles due-north of Grand Canyon Village, and roughly southwest of the Colorado River. The long ridgeline of "the battleship", is oriented slightly southwest-by-northeast, with the "conning tower", (The Battleship prominence), at the southwest, making up about one fourth of the battleship landform. The striking west Redwall Limestone cliffs, surmounted by the orange-reddish slopes of Supai Group “redbeds”, of The Battleship landform, is offset at the east, by the same Redwall cliffs and orange-red ...

The Alligator (Grand Canyon)
The Alligator (Grand Canyon), is a -elevation summit, a large ridgeline butte, connected to, and below Mohave Point (South Rim), approximately northwest of Grand Canyon Village, Grand Canyon. The ridgeline trends north, and the lower elevation cliff, the tail of the alligator, turns northwest. The Alligator landform is about from the west-flowing Colorado River, and Vishnu Basement Rocks, Granite Gorge. The Alligator lies between the Monument Creek (Grand Canyon) drainage, west, and the Salt Creek (Grand Canyon) drainage, east, both short, south tributaries to the Colorado. The Alligator is composed of bright red-orange Supai Group (four members), (cliff-former, cliffs, and slope-former, slopes), upon a red, Redwall Limestone, large cliff. Also being a cliff-former, the curving "tail-of-the-alligator" is a flat-topped platform of the Redwall Limestone. Geology The Alligator landform is composed of two basic rock units: the prominence-Supai Group (roughly thick), and below ...

Geology Of The Grand Canyon Area
The geology of the Grand Canyon area includes one of the most complete and studied sequences of rock (geology), 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 lithified sand dunes from an extinct desert. There are at least 14 known Unconformity, unconformities in the geologic record found in the Grand Canyon. Uplift of the region started about 75 million years ago during the Laramide orogeny; a mountain-building event that is largely responsible for creating the Rocky Mountains to the east. In total, the Colorado Plateau was uplifted an estimated . The adjacent Basin and Range Province to the west started to form about 18 million years ago as th ...

Supai Group
The Supai Group is a slope-forming section of red bed deposits found in the Colorado Plateau. The group was laid down during the Pennsylvanian to Lower Permian. Cliff-forming interbeds of sandstone are noticeable throughout the group. The Supai Group is especially exposed throughout the Grand Canyon in northwest Arizona, as well as local regions of southwest Utah, such as the Virgin River valley region. It occurs in Arizona at Chino Point, Sycamore Canyon, and famously at Sedona as parts of Oak Creek Canyon. In the Sedona region, it is overlain by the Hermit Formation, and the colorful Schnebly Hill Formation. The Supai Group is coeval with the Hermosa Group of east and south Utah; the Hermosa Group extended southeastwards from Utah to Durango, extreme southwest Colorado, and adjacent to the Hermosa type section. The Supai Group was originally designated as the Supai Formation by N.H. Darton in 1910 for exposures at Supai, Arizona. It was first raised to group stratigrap ...

Colorado River
The Colorado River ( es, Río Colorado) is one of the principal rivers (along with the Rio Grande) in the Southwestern United States and northern Mexico. The river drains an expansive, arid drainage basin, watershed that encompasses parts of seven U.S. states and two Mexican states. The name Colorado derives from the Spanish language for "colored reddish" due to its heavy silt load. Starting in the central Rocky Mountains of Colorado, it flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the Mexico–United States border, international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora. Known for its dramatic canyons, whitewater rapids, and eleven National parks of the United States, U.S. National Parks, the Colorado River and its tributaries are a v ...

James Dwight Dana
James Dwight Dana Royal Society of London, FRS FRSE (February 12, 1813 – April 14, 1895) was an American geologist, mineralogist, volcanologist, and zoologist. He made pioneering studies of mountain-building, volcano, volcanic activity, and the origin and structure of continents and oceans around the world. His zoological author abbreviation is Dana. Early life and career Dana was born February 12, 1813, in Utica, New York. His father was merchant James Dana (1780–1860) and his mother was Harriet Dwight (1792–1870). Through his mother he was related to the Dwight New England family of missionaries and educators including uncle Harrison Gray Otis Dwight and first cousin Henry Otis Dwight. He showed an early interest in science, which had been fostered by Fay Edgerton, a teacher in the Utica high school, and in 1830 he entered Yale College in order to study under Benjamin Silliman the elder. Graduating in 1833, for the next two years he was teacher of mathematics to midshi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanologist
A volcanologist, or volcano scientist, is a geologist who focuses on understanding the formation and eruptive activity of volcanoes. Volcanologists frequently visit volcanoes, sometimes active ones, to observe and monitor volcanic eruptions, collect eruptive products including tephra (such as ash or pumice), rock and lava samples. One major focus of inquiry in recent times is the prediction of eruptions to alleviate the impact on surrounding populations and monitor natural hazards associated with volcanic activity. Geologists who research volcanic materials that make up the solid Earth are referred to as igneous petrologists. Etymology The word ''volcanologist'' (or ''vulcanologist'') is derived from the English volcanology (volcano + -logy), which was derived from the French volcanologie (or vulcanologie), which was further derived from the French word volcan (volcano), which was even further derived from Vulcanus, the Latin name of the Roman god of fire and metalworking.
