Sandy River (Kennebec River)
The Sandy River is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed June 30, 2011 tributary of the Kennebec River in the U.S. state of Maine. The Sandy River originates in the Sandy River Ponds () at an elevation of in Sandy River Plantation. The river flows south to a confluence with Chandler Mill Stream in Maine Township E and then easterly to its confluence with Saddleback Stream in Madrid, and Orbeton Stream in Phillips. The river then flows southeasterly through the villages of Phillips and Strong. The river flows south from Strong to Farmington and flows northeasterly from Farmington Falls through New Sharon to discharge into the Kennebec River in Norridgewock a short distance south of the Madison town line. Maine State Route 4 follows the river from the Sandy River Ponds and bridges it at Strong along the way to Farmington, where it is again bridged. The river is bridged once more at Farmington by U. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stereoscopy
Stereoscopy (also called stereoscopics, or stereo imaging) is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. The word ''stereoscopy'' derives . Any stereoscopic image is called a stereogram. Originally, stereogram referred to a pair of stereo images which could be viewed using a stereoscope. Most stereoscopic methods present a pair of two-dimensional images to the viewer. The left image is presented to the left eye and the right image is presented to the right eye. When viewed, the human brain perceives the images as a single 3D view, giving the viewer the perception of 3D depth. However, the 3D effect lacks proper focal depth, which gives rise to the Vergence-Accommodation Conflict. Stereoscopy is distinguished from other types of 3D displays that display an image in three full dimensions, allowing the observer to increase information about the 3-dimensional objects being displayed by head and eye mov ...

Maine
Maine () is a state in the New England and Northeastern regions of the United States. It borders New Hampshire to the west, the Gulf of Maine to the southeast, and the Canadian provinces of New Brunswick and Quebec to the northeast and northwest, respectively. The largest state by total area in New England, Maine is the 12th-smallest by area, the 9th-least populous, the 13th-least densely populated, and the most rural of the 50 U.S. states. It is also the northeasternmost among the contiguous United States, the northernmost state east of the Great Lakes, the only state whose name consists of a single syllable, and the only state to border exactly one other U.S. state. Approximately half the area of Maine lies on each side of the 45th parallel north in latitude. The most populous city in Maine is Portland, while its capital is Augusta. Maine has traditionally been known for its jagged, rocky Atlantic Ocean and bayshore coastlines; smoothly contoured mountains; heavily f ...

Phillips And Rangeley Railroad
The Phillips and Rangeley Railroad was a narrow gauge common carrier railroad in the State of Maine. It connected the towns of Phillips and Rangeley and was built to serve the forestry and resort industries of Franklin County. This railroad pioneered the use of large gauge rolling stock in North America. Earlier freight cars built for the Billerica and Bedford Railroad, the Sandy River Railroad, the Bridgton and Saco River Railroad, the Monson Railroad, the Franklin and Megantic Railroad,''Railroad Commissioners' Report'' State of Maine 1908 p. 135 and the Kennebec Central Railroad had a maximum length of . Phillips and Rangeley Railroad ordered the first cars in 1890 and the subsidiary Eustis Railroad ordered the first cars in 1903. The Portland Company locomotive built in 1890 was 12.5% heavier than any previous gauge locomotive in Maine. The locomotive purchased from Baldwin Locomotive Works the following year was 28% heavier than the Portland locomotive; and its ...

Narrow Gauge Railway
A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge narrower than standard . Most narrow-gauge railways are between and . Since narrow-gauge railways are usually built with tighter curves, smaller structure gauges, and lighter rails, they can be less costly to build, equip, and operate than standard- or broad-gauge railways (particularly in mountainous or difficult terrain). Lower-cost narrow-gauge railways are often used in mountainous terrain, where engineering savings can be substantial. Lower-cost narrow-gauge railways are often built to serve industries as well as sparsely populated communities where the traffic potential would not justify the cost of a standard- or broad-gauge line. Narrow-gauge railways have specialised use in mines and other environments where a small structure gauge necessitates a small loading gauge. In some countries, narrow gauge is the standard; Japan, Indonesia, Taiwan, New Zealand, South Africa, and the Aust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Revolutionary War
The American Revolutionary War (April 19, 1775 – September 3, 1783), also known as the Revolutionary War or American War of Independence, was a major war of the American Revolution. Widely considered as the war that secured the independence of the United States, fighting began on April 19, 1775, followed by the Lee Resolution on July 2, 1776, and the Declaration of Independence on July 4, 1776. The American Patriots were supported by the Kingdom of France and, to a lesser extent, the Dutch Republic and the Spanish Empire, in a conflict taking place in North America, the Caribbean, and the Atlantic Ocean. Established by royal charter in the 17th and 18th centuries, the American colonies were largely autonomous in domestic affairs and commercially prosperous, trading with Britain and its Caribbean colonies, as well as other European powers via their Caribbean entrepôts. After British victory over the French in the Seven Years' War in 1763, tensions between the motherland and he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gravel
Gravel is a loose aggregation of rock fragments. Gravel occurs naturally throughout the world as a result of sedimentary and erosive geologic processes; it is also produced in large quantities commercially as crushed stone. Gravel is classified by particle size range and includes size classes from granule- to boulder-sized fragments. In the Udden-Wentworth scale gravel is categorized into granular gravel () and pebble gravel (). ISO 14688 grades gravels as fine, medium, and coarse, with ranges 2–6.3 mm to 20–63 mm. One cubic metre of gravel typically weighs about 1,800 kg (or a cubic yard weighs about 3,000 lb). Gravel is an important commercial product, with a number of applications. Almost half of all gravel production is used as aggregate for concrete. Much of the rest is used for road construction, either in the road base or as the road surface (with or without asphalt or other binders.) Naturally occurring porous gravel deposits have a ...

Spawn (biology)
Spawn is the Egg cell, eggs and Spermatozoa, sperm released or deposited into water by aquatic animals. As a verb, ''to spawn'' refers to the process of releasing the eggs and sperm, and the act of both sexes is called spawning. Most aquatic animals, except for aquatic mammals and marine reptile, reptiles, reproduce through the process of spawning. Spawn consists of the reproductive cells (gametes) of many aquatic animals, some of which will become fertilized and produce offspring. The process of spawning typically involves females releasing Ovum, ova (unfertilized eggs) into the water, often in large quantities, while males simultaneously or sequentially release spermatozoa (milt) to fertilize the eggs. Most fish reproduce by spawning, as do most other aquatic animals, including crustaceans such as crabs and shrimps, molluscs such as oysters and squid, echinoderms such as sea urchins and sea cucumbers, amphibians such as frogs and newts, aquatic insects such as mayflies and mos ...

Fish Migration
Fish migration is mass relocation by fish from one area or body of water to another. Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousands of kilometres. Such migrations are usually done for better feeding or to reproduce, but in other cases the reasons are unclear. Fish migrations involve movements of schools of fish on a scale and duration larger than those arising during normal daily activities. Some particular types of migration are ''anadromous'', in which adult fish live in the sea and migrate into fresh water to spawn; and ''catadromous'', in which adult fish live in fresh water and migrate into salt water to spawn. Marine forage fish often make large migrations between their spawning, feeding and nursery grounds. Movements are associated with ocean currents and with the availability of food in different areas at different times of year. The migratory movements m ...

Fishing
Fishing is the activity of trying to catch fish. Fish are often caught as wildlife from the natural environment, but may also be caught from stocked bodies of water such as ponds, canals, park wetlands and reservoirs. Fishing techniques include hand-gathering, spearing, netting, angling, shooting and trapping, as well as more destructive and often illegal techniques such as electrocution, blasting and poisoning. The term fishing broadly includes catching aquatic animals other than fish, such as crustaceans ( shrimp/ lobsters/crabs), shellfish, cephalopods (octopus/squid) and echinoderms ( starfish/ sea urchins). The term is not normally applied to harvesting fish raised in controlled cultivations ( fish farming). Nor is it normally applied to hunting aquatic mammals, where terms like whaling and sealing are used instead. Fishing has been an important part of human culture since hunter-gatherer times, and is one of the few food production activities that have persisted ...

Canoe
A canoe is a lightweight narrow water vessel, typically pointed at both ends and open on top, propelled by one or more seated or kneeling paddlers facing the direction of travel and using a single-bladed paddle. In British English, the term ''canoe'' can also refer to a kayak, while canoes are called Canadian or open canoes to distinguish them from kayaks. Canoes were developed by cultures all over the world, including some designed for use with sails or outriggers. Until the mid-19th century, the canoe was an important means of transport for exploration and trade, and in some places is still used as such, sometimes with the addition of an outboard motor. Where the canoe played a key role in history, such as the Northern United States, Canada, and New Zealand, it remains an important theme in popular culture. Canoes are now widely used for competition and pleasure, such as racing, whitewater, touring and camping, freestyle and general recreation. Canoeing has been part ...

Abenaki People
The Abenaki (Abenaki: ''Wαpánahki'') are an Indigenous peoples of the Northeastern Woodlands of Canada and the United States. They are an Algonquian-speaking people and part of the Wabanaki Confederacy. The Eastern Abenaki language was predominantly spoken in Maine, while the Western Abenaki language was spoken in Quebec, Vermont, and New Hampshire. While Abenaki peoples have shared cultural traits, they did not historically have a centralized government. They came together as a post-contact community after their original tribes were decimated by colonization, disease, and warfare. Names The word ''Abenaki'' and its syncope, ''Abnaki,'' are both derived from ''Wabanaki'', or ''Wôbanakiak,'' meaning "People of the Dawn Land" in the Abenaki language. While the two terms are often confused, the Abenaki are one of several tribes in the Wabanaki Confederacy. The name is spelled several ways including Abnaki, Abinaki, and Alnôbak. ''Wôbanakiak'' is derived from ''wôban'' ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maine State Route 4
State Route 4 (SR 4) is a long state highway located in southern and western Maine. It is a major interregional route and the first such route to be designated in the state. The southern terminus is at the New Hampshire border in South Berwick, where it connects to New Hampshire Route 4, and the northern terminus is at Haines Landing on Mooselookmeguntic Lake in Rangeley. Major cities and towns along the length of SR 4 include Sanford, Gorham, Windham, Auburn and Farmington. Route description South Berwick to Alfred SR 4 begins at the New Hampshire state line where NH 4 crosses into South Berwick. It has a brief concurrency with SR 236 in the downtown area before splitting off to the northeast. SR 4 runs in a northeasterly direction, running along the southeastern edge of Berwick and into the town of North Berwick, where it junctions with SR 9 and has a concurrency through downtown, then turns nearly due north.
