Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Alaska Range
The Alaska Range is a relatively narrow, 600-mile-long (950 km) mountain range in the southcentral region of the U.S. state of Alaska, from Lake Clark at its southwest endSources differ as to the exact delineation of the Alaska Range. ThBoard on Geographic Namesentry is inconsistent; part of it designates Iliamna Lake as the southwestern end, and part of the entry has the range ending at the Telaquana and Neacola Rivers. Other sources identify Lake Clark, in between those two, as the endpoint. This also means that the status of the Neacola Mountains is unclear: it is usually identified as the northernmost subrange of the Aleutian Range, but it could also be considered the southernmost part of the Alaska Range. to the White River in Canada's Yukon Territory in the southeast. The highest mountain in North America, Denali, is in the Alaska Range. It is part of the American Cordillera. The Alaska range is one of the higher ranges in the world after the Himalayas and the Andes. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 upgraded ...

Summit Lake (Paxson, Alaska)
Summit Lake is located above the tree line on the south slope of the Alaska Range between miles 192 and 196 of the Richardson Highway (AR-4). It is about north of Valdez, south of Fairbanks, and just south of Isabel Pass at an elevation of . It is also situated within the northeast corner of the census-designated place of Paxson, about upstream (north) of Paxson Lake. It is glacier-fed by several creeks to the north, including Gunn Creek (which flows from the Gulkana Glacier). There are also additional creeks that feed into the lake from the west and southeast. The lake is up to deep and is covered with ice up to thick from November until mid-June. It is also the headwaters of the Gulkana River (a main tributary of the Copper River) well known for its "Copper River Reds" salmon, which migrate in late September to spawn in Gunn Creek on the north end of the lake. The lake is long, wide, and has a surface area of . The area is known for the annual Arctic Man Summit L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Denali Highway
Denali Highway (Alaska Route 8) is a lightly traveled, mostly gravel highway in the U.S. state of Alaska. It leads from Paxson on the Richardson Highway to Cantwell on the Parks Highway. Opened in 1957, it was the first road access to Denali National Park. Since 1971, primary park access has been via the Parks Highway, which incorporated a section of the Denali Highway from Cantwell to the present-day park entrance. The Denali Highway is in length. Conditions The highway is now little used and poorly maintained, and closed to all traffic from October to mid-May each year. Whitfield, p. 399 Only the easternmost and westernmost are paved; whether the remainder should be paved as well is a continual source of debate. Washboarding and extreme dust are common, and the recommended speed limit is . Route description Traveling west, the Denali Highway leaves the Richardson Highway (Alaska Route 4) at Paxson, and climbs steeply up into the foothills of the central Alaska Range. The ...

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

Moraine
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Provenà ...
