Sea Level Datum Of 1929
The National Geodetic Vertical Datum of 1929 is the official name since 1973 of the vertical datum established for vertical control surveying in the United States, United States of America by the General Adjustment of 1929. Originally known as Sea Level Datum of 1929, NGVD 29 was determined and published by the National Geodetic Survey and used to measure the elevation of a point above and depression (geology), depression below mean sea level (MSL). NGVD29 was superseded by the North American Vertical Datum of 1988 (NAVD 88), based upon reference to a single benchmark (referenced to the new International Great Lakes Datum of 1985 local mean sea level height value), although many cities and U.S. Army Corps of Engineers "legacy" projects with established data continued to use the older datum. Methodology Mean sea level was measured at 26 tide gauges: 21 in the United States and 5 in Canada. The datum was defined by the observed heights of mean sea level at the 26 tide gauges and ...

Cinnamon Mountain
Cinnamon Mountain is a summit in San Juan County, Colorado, United States. Description Cinnamon Mountain is located northeast of the community of Silverton and east of Animas Forks, on land administered by the Bureau of Land Management. Cinnamon is situated west of the Continental Divide in the San Juan Mountains which are a subrange of the Rocky Mountains. Precipitation runoff from the mountain drains into the Animas River and topographic relief is significant as the summit rises over above the river in one mile (1.6 km). Access to the mountain is via the Alpine Loop Back Country Byway at Cinnamon Pass. The mountain's toponym has been officially adopted by the United States Board on Geographic Names. Climate According to the Köppen climate classification system, Cinnamon Mountain is located in an alpine subarctic climate zone with cold, snowy winters, and cool to warm summers. Due to its altitude, it receives precipitation all year, as snow in winter and as thundersto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Folklore
Folklore is shared by a particular group of people; it encompasses the traditions common to that culture, subculture or group. This includes oral traditions such as tales, legends, proverbs and jokes. They include material culture, ranging from traditional building styles common to the group. Folklore also includes customary lore, taking actions for folk beliefs, the forms and rituals of celebrations such as Christmas and weddings, folk dances and initiation rites. Each one of these, either singly or in combination, is considered a folklore artifact or traditional cultural expression. Just as essential as the form, folklore also encompasses the transmission of these artifacts from one region to another or from one generation to the next. Folklore is not something one can typically gain in a formal school curriculum or study in the fine arts. Instead, these traditions are passed along informally from one individual to another either through verbal instruction or demonstr ...

Lincoln Memorial
The Lincoln Memorial is a U.S. national memorial built to honor the 16th president of the United States, Abraham Lincoln. It is on the western end of the National Mall in Washington, D.C., across from the Washington Monument, and is in the form of a neoclassical temple. The memorial's architect was Henry Bacon. The designer of the memorial interior's large central statue, ''Abraham Lincoln'' (1920), was Daniel Chester French; the Lincoln statue was carved by the Piccirilli brothers. The painter of the interior murals was Jules Guerin, and the epitaph above the statue was written by Royal Cortissoz. Dedicated in May 1922, it is one of several memorials built to honor an American president. It has always been a major tourist attraction and since the 1930s has sometimes been a symbolic center focused on race relations. The building is in the form of a Greek Doric temple and contains a large seated sculpture of Abraham Lincoln and inscriptions of two well-known speeches by L ...

Granite Dome
Granite domes are domical hills composed of granite with bare rock exposed over most of the surface. Generally, domical features such as these are known as bornhardts. Bornhardts can form in any type of plutonic rock but are typically composed of granite and granitic gneiss. As granitic plutons cool kilometers below the Earth's surface, minerals in the rock crystallize under uniform confining pressure. Erosion brings the rock closer to Earth's surface and the pressure from above the rock decreases; as a result the rock fractures. These fractures are known as exfoliation joints, or sheet fractures, and form in onionlike patterns that are parallel to the land surface. These sheets of rock peel off the exposed surface and in certain conditions develop domical structures. Additional theories on the origin of granite domes involve scarp-retreat and tectonic uplift. Sheet fractures Sheet fractures are arcuate fractures defining slabs of rock that range from 0.5 to 10 meters thic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tertiary
Tertiary ( ) is a widely used but obsolete term for the geologic period from 66 million to 2.6 million years ago. The period began with the demise of the non-avian dinosaurs in the Cretaceous–Paleogene extinction event, at the start of the Cenozoic Era, and extended to the beginning of the Quaternary glaciation at the end of the Pliocene Epoch. The time span covered by the Tertiary has no exact equivalent in the current geologic time system, but it is essentially the merged Paleogene and Neogene periods, which are informally called the Early Tertiary and the Late Tertiary, respectively. The Tertiary established the Antarctic as an icy island continent. Historical use of the term The term Tertiary was first used by Giovanni Arduino during the mid-18th century. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in Northern Italy. Later a fourth period, the Quaternary, was applied. In the early d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Contact Metamorphism
Metamorphism is the transformation of existing rock (the protolith) to rock with a different mineral composition or texture. Metamorphism takes place at temperatures in excess of , and often also at elevated pressure or in the presence of chemically active fluids, but the rock remains mostly solid during the transformation. Metamorphism is distinct from weathering or diagenesis, which are changes that take place at or just beneath Earth's surface. Various forms of metamorphism exist, including regional, contact, hydrothermal, shock, and dynamic metamorphism. These differ in the characteristic temperatures, pressures, and rate at which they take place and in the extent to which reactive fluids are involved. Metamorphism occurring at increasing pressure and temperature conditions is known as ''prograde metamorphism'', while decreasing temperature and pressure characterize ''retrograde metamorphism''. Metamorphic petrology is the study of metamorphism. Metamorphic petrologists re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mississippian Age
The Mississippian ( , also known as Lower Carboniferous or Early Carboniferous) is a subperiod in the geologic timescale or a subsystem of the geologic record. It is the earlier of two subperiods of the Carboniferous period lasting from roughly 358.9 to 323.2 million years ago. As with most other geochronologic units, the rock beds that define the Mississippian are well identified, but the exact start and end dates are uncertain by a few million years. The Mississippian is so named because rocks with this age are exposed in the Mississippi Valley. The Mississippian was a period of marine transgression in the Northern Hemisphere: the sea level was so high that only the Fennoscandian Shield and the Laurentian Shield were dry land. The cratons were surrounded by extensive delta systems and lagoons, and carbonate sedimentation on the surrounding continental platforms, covered by shallow seas. In North America, where the interval consists primarily of marine limestones, it is treate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yule Creek
Yule, actually Yuletide ("Yule time") is a festival observed by the historical Germanic peoples, later undergoing Christianised reformulation resulting in the now better-known Christmastide. The earliest references to Yule are by way of indigenous Germanic month names ' (Before Yule) or ' and ' (After Yule). Scholars have connected the celebration to the Wild Hunt, the god Odin and the pagan Anglo-Saxon Mōdraniht. Terms with an etymological equivalent to ''Yule'' are used in the Nordic countries for Christmas with its religious rites, but also for the holidays of this season. ''Yule'' is also used to a lesser extent in English-speaking countries to refer to Christmas. Customs such as the Yule log, Yule goat, Yule boar, Yule singing, and others stem from Yule. A number of Neopagans have introduced their own rites. Etymology ''Yule'' is the modern English representation of the Old English words ' or ' and ' or ''ġéoli'', with the former indicating the 12-day festival of "Y ...

Slate River (Colorado)
Slate River is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed March 18, 2011 tributary of the East River in Gunnison County, Colorado, United States. It flows south from a source near Yule Pass in the Raggeds Wilderness to a confluence with the East River southeast of Crested Butte, Colorado. A BLM-managed campground named Oh Be Joyful lies along the river. Usage and conservation Recreational use of the Slate River has risen rapidly during the 2010s. In response, the nearby town of Crested Butte, the Crested Butte Land Trust, the Bureau of Land Management, Colorado Parks and Wildlife, and other people and organizations formed a working group to focus on preserving the river's water quality and ecosystem.
