Devils Paw
Devils Paw (or Devil's Paw, or Boundary Peak 93) is the high point of the Juneau Icefield, on the Alaska-British Columbia border. It is a part of the Boundary Ranges of the Coast Mountains. It is notable for its steep rise above the low local terrain. Its height is sometimes given as 8,507 feet (2,593 m). Devils Paw is located on the northeast side of the Juneau Icefield, and its north slopes feed Tulsequah Lake and the Tulsequah Glacier. Its south slope forms the head of the picturesquely-named "Hades Highway", which is the eastern extremity of the Icefield. To illustrate the steepness of the peak: the north face drops in approximately three miles (4.8 km), and the southeast side drops in about seven miles (11.3 km). __NOTOC__ Climate Based on the Köppen climate classification, Devils Paw is located in a subpolar oceanic climate zone, with long, cold, snowy winters, and cool summers. Temperatures can drop below −20 °C with wind chill factors below −30 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devils Thumb
Devils Thumb, or Taalkhunaxhkʼu Shaa in Tlingit language, Tlingit, is a mountain in the Stikine Icecap region of the Alaska–British Columbia border, near Petersburg, Alaska, Petersburg. It is named for its projected thumb-like appearance. Its name in the Tlingit language means "the mountain that never flooded" and is said to have been a refuge for people during Aangalakhu ("the Great Flood"). It is one of the peaks that marks the border between the United States and Canada, and is also listed on maps as Boundary Peak 71. Devils Thumb is a very challenging climb even for advanced Mountaineering, mountain climbers. Location Devils Thumb is part of a group of striking, difficult rock peaks on the western edge of the Stikine Icecap. The Stikine Icecap occupies the crest of the Boundary Ranges, a subrange of the Coast Mountains spanning the Canada–United States border, north of the mouth of the Stikine River. Other peaks in the area include the Witches Tits and Cat's Ears Spi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Canada–United States Border
The border between Canada and the United States is the longest international border in the world. The terrestrial boundary (including boundaries in the Great Lakes, Atlantic, and Pacific coasts) is long. The land border has two sections: Canada's border with the contiguous United States to its south, and with the U.S. state of Alaska to its west. The bi-national International Boundary Commission deals with matters relating to marking and maintaining the boundary, and the International Joint Commission deals with issues concerning boundary waters. The agencies currently responsible for facilitating legal passage through the international boundary are the Canada Border Services Agency (CBSA) and U.S. Customs and Border Protection (CBP). History 18th century The Treaty of Paris of 1783 ended the American Revolutionary War between Great Britain and the United States. In the second article of the Treaty, the parties agreed on all boundaries of the United States, including, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Alaska
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Oceanic Climate
An oceanic climate, also known as a marine climate, is the humid temperate climate sub-type in Köppen classification ''Cfb'', typical of west coasts in higher middle latitudes of continents, generally featuring cool summers and mild winters (for their latitude), with a relatively narrow annual temperature range and few extremes of temperature. Oceanic climates can be found in both hemispheres generally between 45 and 63 latitude, most notably in northwestern Europe, northwestern America, as well as New Zealand. Precipitation Locations with oceanic climates tend to feature frequent cloudy conditions with precipitation, low hanging clouds, and frequent fronts and storms. Thunderstorms are normally few, since strong daytime heating and hot and cold air masses meet infrequently in the region. In most areas with an oceanic climate, precipitation comes in the form of rain for the majority of the year. However, some areas with this climate see some snowfall annually during winter. ...

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] |
