North Arapaho Peak
North Arapaho Peak is the highest summit of the Indian Peaks in the northern Front Range of the Rocky Mountains of North America. The thirteener is located in the Indian Peaks Wilderness, west-southwest ( bearing 245°) of the Town of Ward, Colorado, United States, on the Continental Divide separating Roosevelt National Forest and Boulder County from Arapaho National Forest and Grand County. Between North Arapaho Peak and neighboring South Arapaho Peak sits Arapaho Glacier, which is owned by the City of Boulder as part of its water supply. North and South Arapahoe Peaks are connected by a 0.8 mile, Class 4 connecting ridge. West of these peaks is Arapaho Pass. Climate According to the Köppen climate classification system, the 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 thunderstorms in summer, with a dry period in late ...

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 NGVD29 was superseded by the North American Vertical Datum of 1988 (NAVD 88), based upon reference to a single benchmark (referenced to the new International Great Lakes Datum of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 ...

Indian Peaks Wilderness
The Indian Peaks Wilderness is a wilderness area in north central Colorado managed jointly by the United States Forest Service and the National Park Service within the Arapaho and Roosevelt National Forests and small parts of the southern section of Rocky Mountain National Park. It borders the James Peak Wilderness to the south, and straddles the Continental Divide. The area receives high visitation due to its proximity to the Denver metropolitan area. Geography The area encompasses a stretch of the Front Range. It includes 7 peaks over in elevation. The highest point is North Arapaho Peak at . The peaks are all within of elevation of each other. A portion of the area, encompassing the headwaters of North Boulder Creek, is closed to the public as it is the City of Boulder watershed. Peak names Many of the peaks inside the wilderness area are named after western Native American tribes. The naming scheme was the idea of botany teacher Ellsworth Bethel. By 1914, few of th ...

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 ave ...

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] |
