Mauna Kea

Mauna Kea. Mauna Kea is an inactive volcano in the Hawai islands, one of five volcanic tips that together form the island of Hawaii. It is the highest mountain of the world when it is measured of base to the tip, his base that is about 19,678 feet (5998 ms) under surface of the Pacific Ocean, that would bring its overall height on 33,474 feet (10,203 ms). In they hawaiian, the kea of mauna means the "white mountain", a reference to the fact that it is regularly snow or freezing-capsulado during the northern winter of the hemisphere. Its higher point, Puu Wekiu (one of numerous cones of the ash in the summit), is the highest point of the state of Hawaii in 13.796 feet (4,205 ms). After the hundreds of thousands of years of the building itself for above by volcanic activity, the height of the mountain it is diminishing slowly whereas its massive weight presses the seafloor Pacific. Although the snow and the ice now happen mainly in the period as of November with march, Mauna Kea had ice sockets (throughout all the year) permanent during the Pleistocene ages of ice (Woodcock ET al., 1970). The summit has been demonstrating the evidence of four periods of glaciation during the 200,000 last years, the last conclusion for approximately 11,000 years, when the age of more recent ice finished. The dense rock in the well-known mine of adz near the summit is created to be formed when lava entered eruption underneath a glacier. The hills (of the east) of windward are covered in tropical forest between near 1500 and 5200 feet (m) the elevation 450-1600. Underneath this they are the extensive agricultural regions that before included extensive areas of the sugar cane. With the collapse of the sugar industry in years 90, much of this earth is idling or used for the eucalyptus that cultivate for the wood pulp, the cattles which they pastan, or to cultivate in reduced scale. Between 5200 and 8000 feet (1600 and 2400 m) it is an Earth bandage of the farm, that was before forest of koa-mamane but it has become almost entirely the grass. This area has suffered of the heavy infestaciones of gorse, an invading species in Hawaii. Most of the hills of the north and the west they are also grass. Palila, put in danger pinzo'n-like honeycreeper, feeds almost exclusively in the seeds on mamane and lives in forest on mamane-naio in the hill of the west. A great amount of wild ewes inhabits the superior elevations, and has had a severe impact in the native vegetation. The elevation and the location of Mauna Kea have made him an important location for the atmospheric and astronomical observations. The summit is on approximately 40% of the Earth atmosphere and 90% of the water steam, considering exceptionally clear images. In addition, the tip is on the investment layer, giving a term of up to 300 nights clear per year well. Also, in the latitude 20°N, of northern and southern skies is visible much. The fact that it is a volcano of the protector has meant who the transport of the way to the summit is relatively easy. All these factors have made Mauna Kea a target first for astronomy outpost, and the summit is homemade to many diverse observatories. The construction of telescopes in Mauna Kea has been a source of the controversy in recent years due to the enumerated qualities above, it is a location highly favored and the area of the summit is [ [ ian ] ] tight groups that turn has protested that construction of telescopes additional, which it implies considerable environmental damage in the form of cones of the ash which they describe and as condensations, is affecting sacred sites (the summit of Mauna Kea is the home of the goddess of the snow, Poliahu). In addition, the area of the summit is homemade to a unique insect, the insect of wekiu, that it feeds in the insects blown until the cold summit and taken in snow. The studies in the impact of telescopes in populations of the insect of wekiu have been little conclusive, with accusations of overcollecting and diagonal between the diverse parties.
