John Quincy Adams Rollins
Rollins Pass, elevation , is a mountain pass and active archaeological siteLaBelle, Jason M. & Pelton, Spencer R. "Communal hunting along the Continental Divide of Northern Colorado: Results from the Olson game drive (5BL147)", 2013 in the Southern Rocky Mountains of north-central Colorado in the United States. The pass is located on and traverses the Continental Divide of the Americas at the crest of the Front Range southwest of Boulder and is located approximately five miles east and opposite the resort in Winter Park—in the general area between Winter Park and Rollinsville. Rollins Pass is at the boundaries of Boulder, Gilpin, and Grand counties. Over the past 10,000 years, the pass provided a route over the Continental Divide between the Atlantic Ocean watershed of South Boulder Creek (in the basin of the South Platte River) with the Pacific Ocean watershed of the Fraser River, a tributary of the Colorado River. The abandoned rail route over Rollins Pass was nominated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleo-Indian
Paleo-Indians were the first peoples who entered and subsequently inhabited the Americas towards the end of the Late Pleistocene period. The prefix ''paleo-'' comes from . The term ''Paleo-Indians'' applies specifically to the lithic period in the Western Hemisphere and is distinct from the term ''Paleolithic''.''Paleolithic'' specifically refers to the period between million years ago and the end of the Pleistocene in the Eastern Hemisphere. It is not used in New World archaeology. Traditional theories suggest that big-animal hunters crossed the Bering Strait from North Asia into the Americas over a land bridge (Beringia). This bridge existed from 45,000 to 12,000 BCE (47,000–14,000 BP). Small isolated groups of hunter-gatherers migrated alongside herds of large herbivores far into Alaska. From BCE ( BP), ice-free corridors developed along the Pacific coast and valleys of North America. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Platte River
The South Platte River is one of the two principal tributaries of the Platte River. Flowing through the U.S. states of Colorado and Nebraska, it is itself a major river of the American Midwestern United States, Midwest and the American Southwestern United States, Southwest/Mountain States, Mountain West. Its drainage basin includes much of the eastern flank of the Rocky Mountains in Colorado, much of the populated region known as the Colorado Front Range and Colorado Eastern Plains, Eastern Plains, and a portion of southeastern Wyoming in the vicinity of the city of Cheyenne, Wyoming, Cheyenne. It joins the North Platte River in western Nebraska to form the Platte, which then flows across Nebraska to the Missouri River, Missouri. The river serves as the principal source of water for eastern Colorado. In its valley along the foothills in Colorado, it has permitted agriculture in an area of the Colorado Piedmont and Great Plains that is otherwise arid. Description The rive ...

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 United States Coast and 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 five in Canada. The datum was defined by the observed heights of mean sea level at the ...

La Veta Pass
La Veta Pass is the name associated with two mountain passes in the Sangre de Cristo Mountains of south-central Colorado in the United States, both on the boundary between Costilla and Huerfano counties. Old La Veta Pass (officially La Veta Pass), elevation , was at one time a main travel route between the San Luis Valley and Walsenburg, first on the narrow gauge Denver and Rio Grande Railway, and later on a wagon road and then highway following the same alignment. The route featured two tight curves on the eastern approach to the summit, making the grade feasible for railroad operation, but leaving the route less than satisfactory as a highway. It is now an unpaved and lightly traveled back road. New La Veta Pass (officially North La Veta Pass), elevation , lies about 1.6 miles northeast of the old pass and is now the principal highway route through this part of the mountain range, carrying U.S. Highway 160. While this new route is slightly higher, it has no sharp curves and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fremont Pass (Colorado)
Fremont Pass is a mountain pass in central Colorado, in the Rocky Mountains of the western United States. It forms the continental divide on the border between Lake County and Summit County. The pass is named for John C. Frémont, an explorer of the American West who discovered the pass while traversing present-day Colorado during the 1840s. The pass provides a route between the upper valley of the Blue River, a tributary of the Colorado River, with the headwaters of the Arkansas River to the south. The pass summit is the site of Climax Mine, a molybdenum mine. The pass is traversed by State Highway 91. Despite being one of the highest mountain passes in the state, the only steep part is the switchback on the final ascent toward the Climax mine on the south side. The rest of the pass is gentle. Climate Railway The Denver, South Park and Pacific Railroad built a narrow gauge railway over Fremont Pass in 1884. It was sold in foreclosure proceedings to the Denver ...

Sobriquet
A sobriquet ( ) is a descriptive nickname, sometimes assumed, but often given by another. A sobriquet is distinct from a pseudonym in that it is typically a familiar name used in place of a real name without the need for explanation; it may become more familiar than the original name. An example is Mohandas Gandhi, who is better known as Mahatma Gandhi ("mahatma" means "great soul" in Sanskrit). The term ''sobriquet'' is equally applicable as a name for a person, group of people, historical event, or place. Well-known places often have sobriquets, such as New York City, often called the " Big Apple", or Rome, the "Eternal City", or Vienna, the "Golden Apple". Etymology The modern French and English spelling is . Two earlier variants are and . The first variant, "soubriquet", dates from the 15th century and is rarely used now, in English or French. The early 14th-century ''soubzsbriquez'' meant a "little blow under the chin" in French, also described as a chuck under the ch ...

Geographic Names Information System
The Geographic Names Information System (GNIS) is a database of name and location information about more than two million physical and cultural features, encompassing the United States and its territories; the Compact of Free Association, associated states of the Marshall Islands, Federated States of Micronesia, and Palau; and Antarctica. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names. Data were collected in two phases. Although a third phase was considered, which would have handled name changes where local usages differed from maps, it was never begun. The database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Board On Geographic Names
The United States Board on Geographic Names (BGN) is a Federal government of the United States, federal body operating under the United States Secretary of the Interior. The purpose of the board is to establish and maintain uniform usage of geography, geographic names throughout the federal government of the United States. History Following the American Civil War, more and more American pioneer, American settlers began moving westward, prompting the Federal government of the United States, U.S. federal government to pursue some sort of consistency for referencing landmarks on maps and in official documents. As such, on January 8, 1890, Thomas Corwin Mendenhall, superintendent of the United States Coast and Geodetic Survey Office, wrote to 10 noted geographers "to suggest the organization of a Board made up of representatives from the different Government services interested, to which may be referred any disputed question of geographical orthography." President Benjamin Harrison si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on its hundredth anniversary, was "Earth Science in the Pub ...
