Thompson Pass (Canada)
Thompson Pass is a 2,600 foot-high (855 meter-high) gap in the Chugach Mountains northeast of Valdez, Alaska.Geographic Names Information Service"Thompson Pass, Alaska" U.S. Geological Survey. Accessed July 2, 2009. It is the snowiest weather station in Alaska, recording of snow per year on average.Desert Research Institute Western Regional Climate Center. Accessed July 2, 2009. In the winter of 1952–1953, of snow fell—the most ever recorded in one season at one location in Alaska. It is not the most snow ever recorded in one season at one location anywhere in the fifty states as that record belongs to Mount Baker Ski Resort at in 1998–99. The pass also holds the Alaska record for the most snow in a single day: fell on December 29, 1955. The pass was named in 1899 by U.S. Army captain William Abercrombie "in compliment to Hon. Frank Thomson, of Pennsylvania", but he spelled the name "Thompson" on his sketched map, and that spelling stuck. The pass had been used ...

Richardson Highway
The Richardson Highway is a highway in the U.S. state of Alaska, running 368 miles (562 km) and connecting Valdez to Fairbanks. It is marked as Alaska Route 4 from Valdez to Delta Junction and as Alaska Route 2 from there to Fairbanks. It also connects segments of Alaska Route 1 between the Glenn Highway and the Tok Cut-Off. The Richardson Highway was the first major road built in Alaska. History A pack trail from the port at Valdez to Eagle, a distance of about 409 miles (660 km), was built in 1898 by the U.S. Army to provide an "all-American" route to the Klondike gold fields. After the rush ended, the Army kept the trail open in order to connect its posts at Fort Liscum, in Valdez, and Fort Egbert, in Eagle. The Fairbanks gold rush in 1902, and the construction of a WAMCATS telegraph line along the trail in 1903, made the Valdez-to-Eagle trail one of the most important access routes to the Alaska Interior, so in 1910, the Alaska Road Commission up ...

Snowboarding
Snowboarding is a recreational and competitive activity that involves descending a snow-covered surface while standing on a snowboard that is almost always attached to a rider's feet. It features in the Winter Olympic Games and Winter Paralympic Games. Snowboarding was developed in the United States, inspired by skateboarding, sledding, surfing, and skiing. It became popular around the globe, and was introduced as a Winter Olympic Sport at Nagano in 1998 and featured in the Winter Paralympics at Sochi in 2014. , its popularity (as measured by equipment sales) in the United States peaked in 2007 and has been in a decline since. History The first snowboards were developed in 1965 when Sherman Poppen, an engineer in Muskegon, Michigan, invented a toy for his daughters by fastening two skis together and attaching a rope to one end so he would have some control as they stood on the board and glided downhill. Dubbed the " snurfer" (combining snow and surfer) by his wife Nanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keystone Canyon
Keystone Canyon is a gorge near Valdez in the U.S. state of Alaska. Situated at an elevation of , its walls are almost perpendicular. It measures in length, connecting the upper and lower valleys of Lowe River. Geography In Keystone Canyon, the mother rock of the country shows up to good advantage. It is all slate. Its cleavage is nearly vertical and easy to drill, except where small seams of quartz exist. The slate rock on the south side of the summit is firm and solid as a rule, but on the north side it is very much disintegrated. The bed of the canyon varies from in width. The vegetation growing on the low bottoms, consisting of grass, brush, and trees, indicates that, as a rule, the water does not rise more than in nearly the whole length of the canyon. Keystone Canyon is entered by going through a low pass in a spur divide, which forms the west side of the mouth of the canyon. The east wall is more abrupt than the west wall. There is but little side drainage to the canyon, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Billy Mitchell (Chugach Mountains)
Mount Billy Mitchell is a prominent peak located in the Chugach Mountains, east of Valdez and west of the Copper River in the U.S. state of Alaska. This mountain forms a prominent and easily visible landmark between mile markers 43 and 51 of the Richardson Highway, as the highway passes just to its west between Tonsina and the Thompson Pass (see photograph). Mount Billy Mitchell was named for William "Billy" Mitchell (18791936), a brigadier general of the United States Army Air Service who is often referred to as the "father of the United States Air Force". Naming In response to the Klondike Gold Rush, the United States Army established numerous military outposts throughout the District of Alaska. As a lieutenant in the United States Army Signal Corps, Mitchell was stationed in Alaska at that time. On May 26, 1900, the United States Congress appropriated $450,000 in order to establish a communications system to connect the many isolated and widely separated ...

Color Post Card
Color (American English) or colour (British English) is the visual perceptual property deriving from the spectrum of light interacting with the photoreceptor cells of the eyes. Color categories and physical specifications of color are associated with objects or materials based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space, colors can be identified numerically by their coordinates. Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully explain the psychophysical perception of color appearance. Color science includes the perception of color by the eye and brain, the origin of color in materials, color theory in art, and the physics of electromagne ...

SNOTEL
300px, Data from a SNOTEL site in Elko County, Nevada SNOTEL is an automated system of snowpack and related climate sensors operated by the Natural Resources Conservation Service (NRCS) of the United States Department of Agriculture in the Western United States. There are over 730 SNOTEL (or snow telemetry) sites in 11 states, including Alaska. The sites are generally located in remote high-mountain watersheds where access is often difficult or restricted. Access for maintenance by the NRCS includes various modes from hiking and skiing to helicopters. All SNOTEL sites measure snow water content, accumulated precipitation, and air temperature. Some sites also measure snow depth, soil moisture and temperature, wind speed, solar radiation, humidity, and atmospheric pressure. These data are used to forecast yearly water supplies, predict floods, and for general climate research. History Installation of SNOTEL began in the mid-1960s. Its use in climate forecasting was not ori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snow

A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low. ...—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or Sublimation (phase transition), sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air.

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] |
Tundra
In physical geography, tundra () is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. The term ''tundra'' comes through Russian (') from the Kildin Sámi word (') meaning "uplands", "treeless mountain tract". There are three regions and associated types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra. Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline. The tundra soil is rich in nitrogen and phosphorus. The soil also contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide in the permafrost, making the tundra soil a carbon sink. As global warming heats the ecosystem and causes soil thawing, the permafrost carbon cycle accelerates and releases much of these soil-conta ...

The Milepost
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a v ...
