Mount Jarvis
Mount Jarvis is an eroded shield volcano in the Wrangell Mountains of eastern Alaska. It is located in Wrangell-Saint Elias National Park about east of the summit of Mount Wrangell. The mountain sits at the northeastern edge of the massive ice-covered shield of Wrangell, rising nearly above it in a spectacular series of cliffs and icefalls. When seen from above, Mount Jarvis is distinctly dumbbell-shaped, with two prominent peaks connected by a narrower ridge. The mountain's main summit is , making it one of numerous thirteeners (peaks between 13,000 and 13,999 feet in elevation) in Alaska. The second summit is located about to the north-northwest, reaching with over of prominence above the connecting saddle, thus qualifying it as an independent peak on the list of thirteeners as well. The entire summit area including both peaks and the ridge is covered in glacial ice. The steep, rocky eastern and western faces of Mount Jarvis form headwalls above the cirques of the ...

David H
David (; , "beloved one") (traditional spelling), , ''Dāwūd''; grc-koi, Δαυΐδ, Dauíd; la, Davidus, David; gez , ዳዊት, ''Dawit''; xcl, Դաւիթ, ''Dawitʿ''; cu, Давíдъ, ''Davidŭ''; possibly meaning "beloved one". was, according to the Hebrew Bible, the Kings of Israel and Judah, third king of the Kingdom of Israel (united monarchy), United Kingdom of Israel. In the Books of Samuel, he is described as a young shepherd and Lyre, harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges David and Jonathan, a notably close friendship with Jonathan (1 Samuel), Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

USGS
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredth anniv ...

Point Barrow
Point Barrow or Nuvuk is a headland on the Arctic coast in the U.S. state of Alaska, northeast of Utqiaġvik (formerly Barrow). It is the northernmost point of all the territory of the United States, at , south of the North Pole. (The northernmost point on the North American mainland, Murchison Promontory in Canada, is farther north.) Point Barrow is an important geographical landmark, marking the limit between two marginal seas of the Arctic Ocean, the Chukchi Sea to the west and the Beaufort Sea to the east. It was named by English explorer Frederick William Beechey in 1826 for Sir John Barrow, a statesman and geographer of the British Admiralty. The water around it is normally ice-free for two or three months a year, but this was not the experience of the early explorers. Beechey could not reach it by ship and had to send a ship's boat ahead. In 1826 John Franklin tried to reach it from the east and was blocked by ice. In 1837 Thomas Simpson walked 50 miles west to Poin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctic Ocean
The Arctic Ocean is the smallest and shallowest of the world's five major oceans. It spans an area of approximately and is known as the coldest of all the oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea. It has been described approximately as an estuary of the Atlantic Ocean. It is also seen as the northernmost part of the all-encompassing World Ocean. The Arctic Ocean includes the North Pole region in the middle of the Northern Hemisphere and extends south to about 60°N. The Arctic Ocean is surrounded by Eurasia and North America, and the borders follow topographic features: the Bering Strait on the Pacific side and the Greenland Scotland Ridge on the Atlantic side. It is mostly covered by sea ice throughout the year and almost completely in winter. The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; its salinity is t ...

Overland Relief Expedition
The Overland Relief Expedition, also called the Alaska Relief Expedition or Point Barrow-Overland Relief Expedition, was an expedition in the winter of 1897–1898 by officers of the United States Revenue Cutter Service to save the lives of 265 whalers trapped in the Arctic Ocean by ice around their ships near Point Barrow, Alaska. Background In 1892, the government began a project of importing reindeer from Siberia to Alaska, and teaching the natives how to raise the animals in order to have a steady and dependable food supply. The reindeer were obtained by Captain Michael Healy, who was known and trusted by the Siberian natives. Sheldon Jackson, the General Superintendent of Alaska, used his influence in the United States Congress to raise funds to purchase and care for the animals, and was placed in overall charge of training the herders.Noble, p 3 The project started with seventeen reindeer. From 1892 to 1906, cutters would cruise up the Siberian coast and barter with Chukchi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Copper Glacier
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form (native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create bronze, c. 350 ...
