Dallas Peak
Dallas Peak is a high mountain summit in the Sneffels Range of the Rocky Mountains of North America. The thirteener is located in the Mount Sneffels Wilderness of Uncompahgre National Forest, north by west (bearing 354°) of the Town of Telluride, Colorado, United States, on the drainage divide between Ouray and San Miguel counties. Etymology This mountain's name was officially adopted by the U.S. Board on Geographic Names to commemorate George M. Dallas (1792–1864), American politician and diplomat who served as mayor of Philadelphia from 1828 to 1829, and as the 11th vice president of the United States from 1845 to 1849. Stewart M. Green, ''Scenic Driving Colorado: Exploring the State's Most Spectacular Back Roads'', 2019, Globe Pequot, , page 254. Climate According to the Köppen climate classification system, Dallas Peak is located in an alpine subarctic climate zone with long, cold, snowy winters, and cool to warm summers. Due to its altitude, it receives preci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 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 NGVD29 was superseded by the North American Vertical Datum of 1988 (NAVD 88), based upon reference to a single benchmark (referenced to the new International Great Lakes Datum of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 by the set of elevations of all benc ...

Mount Sneffels Wilderness
The Mount Sneffels Wilderness is a wilderness area in southwest Colorado managed by the Uncompahgre National Forest. It is about west of the town of Ouray. The area is named for Mt. Sneffels, which at is a prominent fourteener in the San Juan Mountains. The word "Sneffels" is likely an Americanization of the Old Norse word for Snæfell "snow mountain," which is also the namesake of the Snæfellsnes The Snæfellsnes () is a peninsula situated to the west of Borgarfjörður, in western Iceland. The Snæfellsjökull volcano, regarded as one of the symbols of Iceland, can be found in the area. With its height of 1446 m, it is the highest ... peninsula and Snæfellsjökull volcano in Iceland.

List Of Mountain Ranges Of Colorado
This is a list of the major mountain ranges in the U.S. State of Colorado. All of these ranges are considered subranges of the Southern Rocky Mountains. As given in the table, topographic elevation is the vertical distance above the reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface. The topographic prominence of a summit is the elevation difference between that summit and the highest or key col to a higher summit. The topographic isolation of a summit is the minimum great-circle distance to a point of equal elevation. All elevations in this article include an elevation adjustment from the National Geodetic Vertical Datum of 1929 (NGVD 29) to the North American Vertical Datum of 1988 (NAVD 88). For further information, please see this United States National Geodetic Surveybr>note If an elevation or prominence is calculated as a range of values, the arithmetic mean is shown. __TOC__ Mountain ranges Gallery Image:Moun ...

Uncompahgre River
The Uncompahgre River is a tributary of the Gunnison River, approximately 75 mi (121 km) long, in southwestern Colorado in the United States. Lake Como at 12,215 ft (3723m) in northern San Juan County, in the Uncompahgre National Forest in the northwestern San Juan Mountains is the headwaters of the river. It flows northwest past Ouray, Ridgway, Montrose, and Olathe and joins the Gunnison at Confluence Park in Delta. The river forms Poughkeepsie Gulch and the Uncompahgre Gorge. The major tributaries are all creeks draining the northwest San Juan Mountains. There are two dams on the Uncompahgre River, a small diversion dam in the Uncompahgre Gorge, and Ridgway Dam below the town of Ridgway which forms Ridgway Reservoir. The river is used for irrigation in the Uncompahgre Valley. Additionally, water from the Gunnison is diverted to the valley via the Gunnison Tunnel. The Uncompahgre is unnavigable except at high water. The name ''Uncompahgre'' () comes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Miguel River (Colorado)
The San Miguel River is a tributary of the Dolores River, approximately long, in southwestern Colorado in the United States. It rises in the San Juan Mountains southeast of Telluride and flows northwest, along the southern slope of the Uncompahgre Plateau, past the towns of Placerville and Nucla and joins the Dolores in western Montrose County approximately 15 miles (24 km) east of the state line with Utah. Geography and protected areas The San Miguel is more or less free-flowing; however, diversion dams dot the river and alter flows. In some parts it is however one of the few remaining naturally functioning rivers of the West. The San Miguel varies in gradient, from extremely steep in its upper reaches (forming a shallow, rocky, unnavigable stream) to more mellow in the lower sections ( of drop, which offers the whitewater boater a variety of runs all within the class II+--III range). All told, the San Miguel drops over from an alpine ecosystem to the desert. The av ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface Runoff
Surface runoff (also known as overland flow) is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or man-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry man-made contaminants or natural forms of pollution (such as rotting leaves). Man-made contaminants in runoff i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subarctic Climate
The subarctic climate (also called subpolar climate, or boreal climate) is a climate with long, cold (often very cold) winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of an ocean, generally at latitudes from 50° to 70°N, poleward of the humid continental climates. Subarctic or boreal climates are the source regions for the cold air that affects temperate latitudes to the south in winter. These climates represent Köppen climate classification ''Dfc'', ''Dwc'', ''Dsc'', ''Dfd'', ''Dwd'' and ''Dsd''. Description This type of climate offers some of the most extreme seasonal temperature variations found on the planet: in winter, temperatures can drop to below and in summer, the temperature may exceed . However, the summers are short; no more than three months of the year (but at least one month) must have a 24-hour average temperature of at least to fall into this category of climate, and the coldest month should a ...

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'' i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vice President Of The United States
The vice president of the United States (VPOTUS) is the second-highest officer in the executive branch of the U.S. federal government, after the president of the United States, and ranks first in the presidential line of succession. The vice president is also an officer in the legislative branch, as the president of the Senate. In this capacity, the vice president is empowered to preside over Senate deliberations at any time, but may not vote except to cast a tie-breaking vote. The vice president is indirectly elected together with the president to a four-year term of office by the people of the United States through the Electoral College. The modern vice presidency is a position of significant power and is widely seen as an integral part of a president's administration. While the exact nature of the role varies in each administration, most modern vice presidents serve as a key presidential advisor, governing partner, and representative of the president. The vice president ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mayor Of Philadelphia
The mayor of Philadelphia is the chief executive of the government of Philadelphia, Pennsylvania, as stipulated by the Charter of the City of Philadelphia. The current mayor of Philadelphia is Jim Kenney. History The first mayor of Philadelphia, Humphrey Morrey, was appointed by the city’s founder, William Penn. Subsequently, Edward Shippen was appointed by Penn as the first mayor under the charter of 1701 and second mayor overall, and then was elected to a second term by the City Council. Subsequent mayors, who held office for one year, were elected by the city council from among their number. No monetary compensation was paid to the earliest office-holders, and candidates often objected strongly to their being selected, sometimes choosing even to pay a fine rather than serve. In 1704 Alderman Griffith Jones was elected but declined to serve, for which he was fined twenty pounds. In 1706, Alderman Thomas Story was similarly fined for refusing office. In 1745, Alderman Abrah ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage Divide
A drainage divide, water divide, ridgeline, watershed, water parting or height of land is elevated terrain that separates neighboring drainage basins. On rugged land, the divide lies along topographical ridges, and may be in the form of a single range of hills or mountains, known as a dividing range. On flat terrain, especially where the ground is marshy, the divide may be difficult to discern. A triple divide is a point, often a summit, where three drainage basins meet. A ''valley floor divide'' is a low drainage divide that runs across a valley, sometimes created by deposition or stream capture. Major divides separating rivers that drain to different seas or oceans are continental divides. The term ''height of land'' is used in Canada and the United States to refer to a drainage divide. It is frequently used in border descriptions, which are set according to the "doctrine of natural boundaries". In glaciated areas it often refers to a low point on a divide where it ...
