Semisopochnoi Island
Semisopochnoi Island or Unyak Island (obsolete russian: Семисопочной, modern russian: Семисопочный Semisopochny "having seven hills"; ale, Unyax̂) is part of the Rat Islands group in the western Aleutian Islands of Alaska. The island is uninhabited and provides an important nesting area for maritime birds. The island is of volcanic origin, containing several volcanoes including Mount Cerberus. It has a land area of 85.558 square miles (221.59 square km), measuring 11 miles (18 km) in length and 12 miles (20 km) in width. At 179°46' East (+179.7667) (in the Eastern Hemisphere), the easternmost tip of Semisopochnoi is, by longitude, the easternmost land location in the United States and North America. Semisopochnoi sits only 14 minutes (0.2333 degrees) or west of the 180th meridian. Wildlife Semisopochnoi has no native land mammals.

Aleutian Islands
The Aleutian Islands (; ; ale, Unangam Tanangin,”Land of the Aleuts", possibly from Chukchi language, Chukchi ''aliat'', "island"), also called the Aleut Islands or Aleutic Islands and known before 1867 as the Catherine Archipelago, are a chain of 14 large volcanic islands and 55 smaller islands. Most of the Aleutian Islands belong to the U.S. state of Alaska, but some belong to the Russian Federal subjects of Russia, federal subject of Kamchatka Krai. They form part of the Aleutian Arc in the Northern Pacific Ocean, occupying a land area of 6,821 sq mi (17,666 km2) and extending about westward from the Alaska Peninsula toward the Kamchatka Peninsula in Russia, and act as a border between the Bering Sea to the north and the Pacific Ocean to the south. Crossing 180th meridian, longitude 180°, at which point east and west longitude end, the archipelago contains both the westernmost part of the United States by longitude (Amatignak Island) and the easternmost by longitude ( ...

Red-faced Cormorant
The red-faced cormorant (''Urile urile''), red-faced shag or violet shag, is a bird species of the family Phalacrocoracidae. Its range spans from the eastern tip of Hokkaidō in Japan, northern korean peninsula, via the Kuril Islands, the southern tip of the Kamchatka Peninsula and the Aleutian Arc to the Alaska Peninsula and Gulf of Alaska. Taxonomy The red-faced cormorant was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's '' Systema Naturae''. He placed it in the genus '' Pelecanus'' and coined the binomial name ''Pelecanus urile''. Gmelin based his description on the "red faced shag" of John Latham and the "red faced corvarant" of Thomas Pennant. The authors cited different translations of an account of Georg Wilhelm Steller's exploration of the Kamchatka Peninsula. The red-faced cormorant was formerly classified in the genus '' Phalacrocorax''; it was moved to the resurrected genus ''U ...

Cape St
A cape is a clothing accessory or a sleeveless outer garment which drapes the wearer's back, arms, and chest, and connects at the neck. History Capes were common in medieval Europe, especially when combined with a hood in the chaperon. They have had periodic returns to fashion - for example, in nineteenth-century Europe. Roman Catholic clergy wear a type of cape known as a ferraiolo, which is worn for formal events outside a ritualistic context. The cope is a liturgical vestment in the form of a cape. Capes are often highly decorated with elaborate embroidery. Capes remain in regular use as rainwear in various military units and police forces, in France for example. A gas cape was a voluminous military garment designed to give rain protection to someone wearing the bulky gas masks used in twentieth-century wars. Rich noblemen and elite warriors of the Aztec Empire would wear a tilmàtli; a Mesoamerican cloak/cape used as a symbol of their upper status. Cloth and clothing ...

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Newfoundland (island)
Newfoundland (, ; french: link=no, Terre-Neuve, ; ) is a large island off the east coast of the North American mainland and the most populous part of the Canadian province of Newfoundland and Labrador. It has 29 percent of the province's land area. The island is separated from the Labrador Peninsula by the Strait of Belle Isle and from Cape Breton Island by the Cabot Strait. It blocks the mouth of the Saint Lawrence River, creating the Gulf of Saint Lawrence, the world's largest estuary. Newfoundland's nearest neighbour is the French overseas collectivity of Saint Pierre and Miquelon. With an area of , Newfoundland is the world's 16th-largest island, Canada's fourth-largest island, and the largest Canadian island outside the North. The provincial capital, St. John's, is located on the southeastern coast of the island; Cape Spear, just south of the capital, is the easternmost point of North America, excluding Greenland.

Cape Spear
Cape Spear (french: Cap d'Espoir) is a headland located on the Avalon Peninsula of Newfoundland near St. John's in the Canadian province of Newfoundland and Labrador. At a longitude of 52°37'W, it is the easternmost point in Canada and North America, excluding Greenland. Cape Spear is within the municipal boundaries of the city of St. John's, located about from downtown St. John's. The Portuguese named this location , meaning "cape of hope", which became in French and finally "Cape Spear". Cape Spear is the trailhead/trail end for two components of the East Coast Trail.

Greenland
Greenland ( kl, Kalaallit Nunaat, ; da, Grønland, ) is an island country in North America that is part of the Kingdom of Denmark. It is located between the Arctic and Atlantic oceans, east of the Canadian Arctic Archipelago. Greenland is the world's largest island. It is one of three constituent countries that form the Kingdom of Denmark, along with Denmark and the Faroe Islands; the citizens of these countries are all citizens of Denmark and the European Union. Greenland's capital is Nuuk. Though a part of the continent of North America, Greenland has been politically and culturally associated with Europe (specifically Norway and Denmark, the colonial powers) for more than a millennium, beginning in 986.The Fate of Greenland's Vikings , by Dale Mackenzie Brown, ''Archaeological Institute of America'', ...

Nordost Rundingen
Nordostrundingen (corrupted from da, Nordøstrundingen which means Northeastern rounding, in English Northeast Foreland), is a headland located at the northeastern end of Greenland. Administratively it is part of the Northeast Greenland National Park. This headland was named by the Denmark expedition 1906–1908. It is an inconspicuous point where the ice slope of the Flade Isblink meets the frozen sea. Easterly point At 11°19'W it is the most easterly point of land relative to either of the Americas (North and South America). Nordøstrundingen is further east than three countries in Africa and even further east than the westernmost point in Europe (excluding the Azores), which is Látrabjarg in Iceland. It is only 1° 49′ from the westernmost point of the European mainland which is in Portugal. Greenland is not part of North America politically, which leads some people to assert that the most easterly point of the continent is the easternmost point in Canada − Cape Spear ...

Anvil Peak
Anvil Peak is a cone volcano located in Aleutian Islands, Alaska, United States. Etymology The volcano was originally named in 1951, on a map by the United States Geological Survey. Its name was taken after a plateau located on the northern side of the volcano's main summit, taking the appearance of an anvil. Location Anvil Peak is located on Semisopochnoi Island, in the Rat Islands of the western Aleutian Islands. It is one of the seven hills with a summit crater on the island. It is the highest point on the island as well as the highest point on all of the Rat Islands. It is located further north than any of the other hills on the island, taking up a large amount of the northern part of the island. The volcano is located away from Atka, from Shemya, and from Attu. Geology Anvil Peak has two summits, which are both volcanic cones. The larger main summit is tall, making it the highest point on the island. This summit is surrounded by ravines, which contain snow at cer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pumice
Pumice (), called pumicite in its powdered or dust form, is a volcanic rock that consists of highly vesicular rough-textured volcanic glass, which may or may not contain crystals. It is typically light-colored. Scoria is another vesicular volcanic rock that differs from pumice in having larger vesicles, thicker vesicle walls, and being dark colored and denser.Jackson, J.A., J. Mehl, and K. Neuendorf (2005) ''Glossary of Geology'' American Geological Institute, Alexandria, Virginia. 800 pp. McPhie, J., M. Doyle, and R. Allen (1993) ''Volcanic Textures A guide to the interpretation of textures in volcanic rocks'' Centre for Ore Deposit and Exploration Studies, University of Tasmania, Hobart, Tasmania..198 pp. Pumice is created when super-heated, highly pressurized rock is violently ejected from a volcano. The unusual foamy configuration of pumice happens because of simultaneous rapid cooling and rapid depressurization. The depressurization creates bubbles by lowering the solubi ...

Dacite
Dacite () is a volcanic rock formed by rapid solidification of lava that is high in silica and low in alkali metal oxides. It has a fine-grained (aphanitic) to porphyritic texture and is intermediate in composition between andesite and rhyolite. It is composed predominantly of plagioclase feldspar and quartz. Dacite is relatively common, occurring in many tectonic settings. It is associated with andesite and rhyolite as part of the subalkaline volcanic rock, subalkaline tholeiite, tholeiitic and calc-alkaline magma series. Composition Dacite consists mostly of plagioclase feldspar and quartz with biotite, hornblende, and pyroxene (augite or enstatite). The quartz appears as rounded, corroded phenocrysts, or as an element of the ground-mass. The plagioclase in dacite ranges from oligoclase to andesine and labradorite. Sanidine occurs, although in small proportions, in some dacites, and when abundant gives rise to rocks that form rhyodacite, transitions to the rhyolites. The rel ...
