Crater Lake
Crater Lake ( Klamath: ''Giiwas'') is a volcanic crater lake in south-central Oregon in the western United States. It is the main feature of Crater Lake National Park and is famous for its deep blue color and water clarity. The lake partly fills a caldera that was formed around 7,700 (± 150) years ago by the collapse of the volcano Mount Mazama. There are no rivers flowing into or out of the lake; the evaporation is compensated for by rain and snowfall at a rate such that the total amount of water is replaced every 250 years. With a depth of , the lake is the deepest in the United States. In the world, it ranks ninth for maximum depth, and third for mean (average) depth. Crater Lake features two small islands. Wizard Island, located near the western shore of the lake, is a cinder cone approximately 316 acres (128 ha) in size. Phantom Ship, a natural rock pillar, is located near the southern shore. Since 2002, one of Oregon's regular-issue license plate designs has featu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rim Village Historic District
Rim Village is the main area for tourist services in Crater Lake National Park in southern Oregon, United States. It is located on the southwest rim of the caldera overlooking Crater Lake. The National Park Service designed Rim Village to concentrate park services at a location that provided easy access to rim trails and view points. Because of the unique rustic architecture of the Rim Village structures and the surrounding park landscape, the area was listed as Rim Village Historic District on the National Register of Historic Places in 1997. Early history Crater Lake lies inside a caldera created 7,700 years ago when the high Mount Mazama collapsed following a large volcanic eruption. Over the following millennium, the caldera was filled with rain water forming today's lake. The Klamath Indians revered Crater Lake for its deep blue waters. In 1853, three gold miners found the lake, and named it Deep Blue Lake. However, because the lake was so high in the Cascade Mounta ...

Vehicle Registration Plates Of Oregon
The U.S. state of Oregon first required its residents to register their motor vehicles in 1905. Registrants provided their own license plates for display until 1911, when the state began to issue plates. , plates are issued by the Oregon Department of Transportation through its Driver & Motor Vehicle Services branch. Front and rear plates are required for most classes of vehicles, while only rear plates are required for motorcycles and trailers. Passenger baseplates 1911 to 1949 No slogans were used on passenger plates during the period covered by this subsection. 1950 to present In 1956, the United States, Canada, and Mexico came to an agreement with the American Association of Motor Vehicle Administrators, the Automobile Manufacturers Association and the National Safety Council that standardized the size for license plates for vehicles (except those for motorcycles) at in height by in width, with standardized mounting holes. The 1955 (dated 1956) issue was the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limnology
Limnology ( ; from Greek λίμνη, ''limne'', "lake" and λόγος, ''logos'', "knowledge") is the study of inland aquatic ecosystems. The study of limnology includes aspects of the biological, chemical, physical, and geological characteristics of fresh and saline, natural and man-made bodies of water. This includes the study of lakes, reservoirs, ponds, rivers, springs, streams, wetlands, and groundwater.Wetzel, R.G. 2001. Limnology: Lake and River Ecosystems, 3rd ed. Academic Press () Water systems are often categorized as either running (lotic) or standing (lentic). Limnology includes the study of the drainage basin, movement of water through the basin and biogeochemical changes that occur en route. A more recent sub-discipline of limnology, termed landscape limnology, studies, manages, and seeks to conserve these ecosystems using a landscape perspective, by explicitly examining connections between an aquatic ecosystem and its drainage basin. Recently, the need ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

O'Higgins/San Martín Lake
The lake known as O'Higgins in Chile and San Martín in Argentina is located around coordinates in Patagonia, between the Aysén del General Carlos Ibáñez del Campo Region and the Santa Cruz Province. General information The lake has a surface area of , an elevation of above mean sea level, and a shoreline length of . Viewed from above, the lake consists of a series of finger-shaped flooded valleys, of which are in Chile and in Argentina, although sources differ on the precise split, presumably reflecting water level variability. The lake is the deepest in the Americas with a maximum depth of near O'Higgins Glacier, and its characteristic milky light-blue color comes from rock flour suspended in its waters. It is mainly fed by the Mayer River and other streams, and its outlet, the Pascua River, discharges water from the lake towards the Pacific Ocean at a rate of . The O'Higgins Glacier flows eastwards towards the lake, as does the Chico Glacier. Both of these glacie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Depth Sounding
Depth sounding, often simply called sounding, is measuring the depth of a body of water. Data taken from soundings are used in bathymetry to make maps of the floor of a body of water, such as the seabed topography. Soundings were traditionally shown on nautical charts in fathoms and feet. The National Oceanic and Atmospheric Administration (NOAA), the agency responsible for bathymetric data in the United States, still uses fathoms and feet on nautical charts. In other countries, the International System of Units (metres) has become the standard for measuring depth. Terminology "Sounding" derives from the Old English ''sund'', meaning "swimming, water, sea"; it is not related to the word ''sound'' in the sense of noise or tones, but to ''sound'', a geographical term. Traditional terms for soundings are a source for common expressions in the English language, notably "deep six" (a sounding of 6 fathoms). On the Mississippi River in the 1850s, the leadsmen also used old-fash ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Vostok
Lake Vostok (russian: озеро Восток, ''ozero Vostok'') is the largest of Antarctica's almost 400 known subglacial lakes.
