Garoutte Creek
Garoutte Creek is a tributary of the Little River in the U.S. state of Oregon. Rising along the Calapooya Divide near the border between Lane and Douglas counties, it flows generally northeast to meet the larger stream near Black Butte. The butte is a dark-colored mountain, the site of a former mine, and the site of a former post office. Little River joins Big River a few miles downstream to form the Coast Fork Willamette River. On older maps, Little River appears as a tributary of Garoutte Creek, also known as Saroutte Creek. However, in 1988 the United States Board on Geographic Names renamed the lower reach of Garoutte Creek so that it became part of Little River. The change rendered the upper reach of Garoutte Creek a tributary of Little River. The only named tributary of Garoutte Creek is Carlson Creek, which enters from the left. Post office The Black Butte Mine, developed by S. P. Garoutte in the 1890s, led to the establishment of a post office at Black Butte. William Ha ...

Cinnabar
Cinnabar (), or cinnabarite (), from the grc, κιννάβαρι (), is the bright scarlet to brick-red form of Mercury sulfide, mercury(II) sulfide (HgS). It is the most common source ore for refining mercury (element), elemental mercury and is the historic source for the brilliant red or scarlet pigment termed vermilion and associated red mercury pigments. Cinnabar generally occurs as a vein-filling mineral associated with recent volcanic activity and alkaline hot springs. The mineral resembles quartz in symmetry and in its exhibiting birefringence. Cinnabar has a mean refractive index near 3.2, a mohs scale of mineral hardness, hardness between 2.0 and 2.5, and a specific gravity of approximately 8.1. The color and properties derive from a structure that is a hexagonal crystalline bravais lattice, lattice belonging to the trigonal crystal system, crystals that sometimes exhibit Crystal twinning, twinning. Cinnabar has been used for its color since antiquity in the Near East ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coast Fork Willamette River
The Coast Fork Willamette River is one of two forks that unite to form the Willamette River in western Oregon in the United States. It is about long, draining an area of the mountains at the south end of the Willamette Valley south of Eugene. Course The Coast Fork Willamette River is formed in southwestern Lane County, in the Calapooya Mountains, by the confluence of the Little River and the Big River. The Coast Fork flows north through the mountains, through the Cottage Grove Lake reservoir, to Cottage Grove, where it receives the Row River from the southeast. It continues north past Creswell and joins the Middle Fork from the south, about southeast of Eugene, to form the Willamette.

Mercury (element)
Mercury is a chemical element with the symbol Hg and atomic number 80. It is also known as quicksilver and was formerly named hydrargyrum ( ) from the Greek words, ''hydor'' (water) and ''argyros'' (silver). A heavy, silvery d-block A block of the periodic table is a set of elements unified by the atomic orbitals their valence electrons or vacancies lie in. The term appears to have been first used by Charles Janet. Each block is named after its characteristic orbital: s-blo ... element, mercury is the only metallic element that is known to be liquid at standard temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature. Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is obtained by Mill (grinding), grinding natural cinnabar or synthetic mercuric sulfide. Mercury is used in ...

Methylmercury
Methylmercury (sometimes methyl mercury) is an organometallic cation with the formula . It is the simplest organomercury compound. Methylmercury is extremely toxic, and its derivatives are the major source of organic mercury for humans. It is a bioaccumulative environmental toxicant. Structure and chemistry "Methylmercury" is a shorthand for the hypothetical "methylmercury cation", sometimes written "''methylmercury(1+) cation''" or "''methylmercury(II) cation''". This functional group is composed of a methyl group bonded to an atom of mercury. Its chemical formula is (sometimes written as ).The Methylmercury compound has an overall charge of +1, with Hg in the +2 oxidation state.Methylmercury exists as a substituent in many complexes of the type (L = Lewis base) and MeHgX (X = anion). As a positively charged ion it readily combines with anions such as chloride (), hydroxide () and nitrate (). It has particular affinity for sulfur-containing anions, particularly thiols (). ...

Environmental Protection Agency
A biophysical environment is a biotic and abiotic surrounding of an organism or population, and consequently includes the factors that have an influence in their survival, development, and evolution. A biophysical environment can vary in scale from microscopic to global in extent. It can also be subdivided according to its attributes. Examples include the marine environment, the atmospheric environment and the terrestrial environment. The number of biophysical environments is countless, given that each living organism has its own environment. The term ''environment'' can refer to a singular global environment in relation to humanity, or a local biophysical environment, e.g. the UK's Environment Agency. Life-environment interaction All life that has survived must have adapted to the conditions of its environment. Temperature, light, humidity, soil nutrients, etc., all influence the species within an environment. However, life in turn modifies, in various forms, its conditions. ...

Superfund Site
Superfund sites are polluted locations in the United States requiring a long-term response to clean up hazardous material contaminations. They were designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980. CERCLA authorized the United States Environmental Protection Agency (EPA) to create a list of such locations, which are placed on the National Priorities List (NPL). The NPL guides the EPA in "determining which sites warrant further investigation" for environmental remediation. , there were 1,329 Superfund sites on the National Priorities List in the United States. Forty-three additional sites have been proposed for entry on the list, and 452 sites have been cleaned up and removed from the list. New Jersey, California, and Pennsylvania have the most sites.

Blackbutte, Oregon
Black Butte was an unincorporated community in Lane County, Oregon, United States. It was located near Black Butte, a dark-colored mountain at the headwaters of the Coast Fork Willamette River, about 20 miles south of Cottage Grove, at the confluence of Garoutte Creek and the Little River. The Black Butte Mine, which operated from the 1890s to the 1960s, was one of the largest mercury mines in the state. Mercury contamination from abandoned mine tailings continues to be a health concern in the area, including mercury-contaminated runoff from Furnace Creek that has made its way to Cottage Grove Lake. The post office at Black Butte was originally named Harris, after William Harris, the first postmaster. Harris post office was established in 1898, and the name changed to Blackbutte in 1901. The office ran until 1957. At one time there was a Black Butte School; in 1932 the Black Butte School District was consolidated with the London School District. See also *List of Superfund site ...

United States Board On Geographic Names
The United States Board on Geographic Names (BGN) is a federal body operating under the United States Secretary of the Interior. The purpose of the board is to establish and maintain uniform usage of geographic names throughout the federal government of the United States. History On January 8, 1890, Thomas Corwin Mendenhall, superintendent of the US Coast and Geodetic Survey Office, wrote to 10 noted geographers "to suggest the organization of a Board made up of representatives from the different Government services interested, to which may be referred any disputed question of geographical orthography." President Benjamin Harrison signed executive order 28 on September 4, 1890, establishing the ''Board on Geographical Names''. "To this Board shall be referred all unsettled questions concerning geographic names. The decisions of the Board are to be accepted y federal departmentsas the standard authority for such matters." The board was given authority to resolve all unsettled ques ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
