Hall Island (Alaska)
Hall Island (russian: Холл) is a small island located to the northwest of St. Matthew Island in the Bering Sea in Alaska, United States. It serves as a haulout site for Pacific walrus. It is in length and has a land area of . The highest point is . Hall Island is uninhabited. It is part of the Bering Sea unit of the Alaska Maritime National Wildlife Refuge. It is one of three hall islands. History Early Russian hunters knew this island as "Ostrov Morzhovoy" ('Walrus Island') (Tevenkov, 1852, mpa 20). The Imperial Russian Hydrographic Department Chart 1427 called it "Ostrov Sindsha" probably for Lt. Sind, its alleged discoverer, in 1764. Commodore Joseph Billings of the Imperial Russian Navy and Lt. Gavril Sarychev anchored between this island and St. Matthew on July 14, 1791 (O.S.). Since 1875, this island has been called "Hall" on American maps, presumably for Lt. Robert Hall, who was with Captain Billings, or also for Cape Hall. Gallery Hall Island, Bering Sea.jpg, ...

Island
An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental and oceanic. There are also artificial islands, which are man-made. Etymology The word ''island'' derives from Middle English ''iland'', from Old English ''igland'' (from ''ig'' or ''ieg'', similarly meaning 'island' when used independently, and -land carrying its contemporary meaning; cf. Dutch ''eiland'' ("island"), German ''Eiland'' ("small island")). However, the spelling of the word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedicularis
''Pedicularis'' is a genus of perennial green root parasite plants currently placed in the family Orobanchaceae (the genus previously having been placed in Scrophulariaceae ''sensu lato''). Description Between 350 and 600 species are accepted by different authorities, mostly from the wetter northern temperate zones, as well as from South America. The highest diversity is in eastern Asia, with 352 species accepted in China alone. Taxonomy The common name lousewort, applied to several species, derives from an old belief that these plants, when ingested, were responsible for lice infestations in livestock. The genus name ''Pedicularis'' is from the Latin ''pediculus'' meaning louse. Selected species *''Pedicularis acaulis'' *''Pedicularis amoena'' *''Pedicularis arguteserrata'' *''Pedicularis ascendens'' *''Pedicularis asparagoides'' *''Pedicularis asplenifolia'' *''Pedicularis attollens'' (little elephant's head) *''Pedicularis baumgartenii'' *''Pedicularis bhutanomuscoide ...

Protected Areas Of Bethel Census Area, Alaska
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark (botany), bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like Scale (anatomy), scales and hair offer further protection from the elements and from predators, with some animals having features such ...

United States Geological Survey
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 hundredt ...

Geographic Names Information System
The Geographic Names Information System (GNIS) is a database of name and locative information about more than two million physical and cultural features throughout the United States and its territories, Antarctica, and the associated states of the Marshall Islands, Federated States of Micronesia, and Palau. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names. Data were collected in two phases. Although a third phase was considered, which would have handled name changes where local usages differed from maps, it was never begun. The database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recorded. Each feature receives a per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polemonium
''Polemonium'', commonly called Jacob's ladders or Jacob's-ladders (the name derived from the Biblical story), is a genus of between 25 and 40 species of flowering plants in the family Polemoniaceae, native to cool temperate to arctic regions of the Northern Hemisphere. One species also occurs in the southern Andes in South America. Many of the species grow at high altitudes, in mountainous areas. Most of the uncertainty in the number of species relates to those in Eurasia, many of which have been synonymized with '' Polemonium caeruleum''. ''Polemonium'' are perennial plants (rarely annual plants) growing 10–120 cm tall with bright green leaves divided into lance-shaped leaflets. They produce blue (rarely white or pink) flowers in the spring and summer. Some species are used as food plants by the larvae of some Lepidoptera species including '' Coleophora polemoniella''. Species Kew's Plants of the World Online accepts 37 species. Many are locally known sim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
