Glacial Erratic Boulders Of The Puget Sound Region
Many glacial erratic boulders (often simply called glacial erratics) can be found in the Puget Sound region as far south as the Yelm, Washington, Yelm area where the Puget Lobe of the glacier reached its maximum extent. The Pleistocene ice age glaciation of Puget Sound created many of the geographical features of the region, including Puget Sound itself, and the erratics are one of the remnants of that age. According to Nick Zentner of Central Washington University Department of Geological Sciences, "Canadian rocks [are] strewn all over the Puget lowland, stretching from the Olympic Peninsula clear over to the Cascade Range." Erratics can be found at altitudes up to about in the Enumclaw, Washington, Enumclaw area, along with kames, drumlins, and perhaps also the unique Mima mounds. The soil of Seattle, the state's largest city, is approximately 80% glacial drift, most of which is Vashon glacial deposits (till), and nearly all of the city's Seven hills of Seattle, major named hills ...

Glacial Erratic
A glacial erratic is a glacially deposited rock (geology), rock differing from the type of country rock (geology), rock native to the area in which it rests. Erratics, which take their name from the Latin word ' ("to wander"), are carried by glacial ice, often over distances of hundreds of kilometres. Erratics can range in size from pebbles to large boulders such as Okotoks Erratic, Big Rock (16,500 metric tons) in Alberta. Geologists identify erratics by studying the rocks surrounding the position of the erratic and the composition of the erratic itself. Erratics are significant because: *They can be transported by glaciers, and are thereby one of a series of indicators which mark the path of prehistoric Glacial motion, glacier movement. Their lithographic origin can be traced to the parent bedrock, allowing for confirmation of the ice flow route. *They can be transported by ice rafting, which allows quantification of the extent of glacial flooding resulting from ice dam failure ...

Greenschist
Greenschists are metamorphic rocks that formed under the lowest temperatures and pressures usually produced by regional metamorphism, typically and 2–10 kilobars (). Greenschists commonly have an abundance of green minerals such as Chlorite group, chlorite, Serpentine subgroup, serpentine, and epidote, and :wikt:platy, platy minerals such as muscovite and platy serpentine. The platiness gives the rock schistosity (a tendency to split into layers). Other common minerals include quartz, orthoclase, talc, carbonate minerals and amphibole (actinolite). Greenschist is a general field petrology, petrologic term for metamorphic rocks, metamorphic or altered mafic volcanic rock. In Europe, the term ''prasinite'' is sometimes used. A ''greenstone'' is sometimes a greenschist but can also be rock types without any schistosity, especially metabasalt (spilite). However, basalts may remain quite black if primary pyroxene does not revert to chlorite or actinolite. To qualify for the name, ...

Conglomerate (geology)
Conglomerate () is a sedimentary rock made up of rounded gravel-sized pieces of rock surrounded by finer-grained sediments (such as sand, silt, or clay). The larger fragments within conglomerate are called clasts, while the finer sediment surrounding the clasts is called the matrix. The clasts and matrix are typically cemented by calcium carbonate, iron oxide, silica, or hardened clay. Conglomerates form when rounded gravels deposited by water or glaciers become solidified and cemented by pressure over time. They can be found in sedimentary rock sequences of all ages but probably make up less than 1 percent by weight of all sedimentary rocks. They are closely related to sandstones in origin, and exhibit many of the same types of sedimentary structures, such as tabular and trough cross-bedding and graded bedding.Boggs, S.

Conservation Easement
In the United States, a conservation easement (also called conservation covenant, conservation restriction or conservation servitude) is a power invested in a qualified land conservation organization called a "land trust", or a governmental (municipal, county, state or federal) entity to constrain, as to a specified land area, the exercise of rights otherwise held by a landowner so as to achieve certain conservation purposes. It is an interest in real property established by agreement between a landowner and land trust or unit of government. The conservation easement "runs with the land", meaning it is applicable to both present and future owners of the land. The grant of conservation easement, as with any real property interest, is part of the chain of title for the property and is normally recorded in local land records. The conservation easement's purposes will vary depending on the character of the particular property, the goals of the land trust or government unit, and the ...

Coupeville, Washington
Coupeville is a town on Whidbey Island, in Island County, Washington, United States. It is the county seat of Island County. The population was 1,942 at the 2020 United States census, 2020 census. History Prior to European settlement, Coupeville and the bay in which it is located, Penn Cove, was inhabited by the Lower Skagit, a Lushootseed-speaking Coast Salish people. There were three villages around the bay, with the largest being at , meaning "snake place", the site of present day Coupeville. There was an abundance of salmon, clams, and other resources, as well as offering easy access to the water, making it an excellent village site. When Europeans arrived to explore the Puget Sound, it was Joseph Whidbey who first visited the bay, naming it Penn Cove in honor of his good friend. Captain George Vancouver later wrote after meeting the Skagit at the village that their population had quickly fallen due to disease. Coupeville was laid out in the 1850s by Captain Thomas Coupe, ...

Interchange (road)
In the field of road transport, an interchange (American English) or a grade-separated junction (British English) is a road junction that uses grade separations to allow for the movement of traffic between two or more roadways or highways, using a system of interconnecting roadways to permit traffic on at least one of the routes to pass through the junction without interruption from crossing traffic streams. It differs from a standard Intersection (road), intersection, where roads cross wikt:at-grade, at grade. Interchanges are almost always used when at least one road is a controlled-access highway (freeway) or a limited-access road, limited-access highway (expressway), though they are sometimes used at junctions between surface streets. Terminology ''Note:'' The descriptions of interchanges apply to countries where vehicles Left- and right-hand traffic, drive on the right side of the road. For left-side driving, the layout of junctions is mirrored. Both North American (NA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diorite
Diorite ( ) is an intrusive rock, intrusive igneous rock formed by the slow cooling underground of magma (molten rock) that has a moderate content of silica and a relatively low content of alkali metals. It is Intermediate composition, intermediate in composition between low-silica (mafic) gabbro and high-silica (felsic) granite. Diorite is found in mountain-building belts (''orogens'') on the margins of continents. It has the same composition as the fine-grained volcanic rock, andesite, which is also common in orogens. Diorite has been used since prehistoric times as decorative stone. It was used by the Akkadian Empire of Sargon of Akkad for funerary sculptures, and by many later civilizations for sculptures and building stone. Description Diorite is an intrusive rock, intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar (typically andesine), biotite, hornblende, and sometimes pyroxene. The chemical composition of diorite is Intermedia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
