North Powder, Oregon
North Powder is a city in Union County, Oregon, United States. The population was 439 at the 2010 census. History North Powder was platted in 1885 or 1886 along the Oregon Railroad and Navigation Company rail line, having been a stage stop before then. David Eccles, a Mormon businessman, created the Hall Brothers Lumber Company in the town once the railway arrived. North Powder prospered because it had an icehouse that supplied the refrigerator cars of Pacific Fruit Express until the icehouse burned down in the 1930s.

City
A city is a human settlement of notable size.Goodall, B. (1987) ''The Penguin Dictionary of Human Geography''. London: Penguin.Kuper, A. and Kuper, J., eds (1996) ''The Social Science Encyclopedia''. 2nd edition. London: Routledge. It can be defined as a permanent and densely settled place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organisations and businesses, sometimes benefiting different parties in the process, such as improving efficiency of goods and service distribution. Historically, city-dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization, more than half of the world population now lives in cities, which has had profound consequ ...

Stage Stop
A stage station or relay station, also known as a staging post, a posting station, or a stage stop, is a place where exhausted horses could be replaced by fresh animals, since a long journey was much faster without delays when horses needed rest. Stage is the space between the places known as stations or stops—known to Europeans as posts or relays. Organised long-distance land travel became known as staging or posting. Stagecoaches, post chaises, private vehicles, individual riders and the like followed the already long-established system for messengers, couriers and letter-carriers. Through metonymy the name stage also came to be used for a stagecoach alone. Posting and staging Purpose Until well into the 19th century an overland traveller anxious to reach a destination as fast as possible depended on animals. Systems of arranging a supply of fresh horses to expedite travel along a particular route had been in use at least as far back as the ancient Romans when they were ...

Population Density
Population density (in agriculture: Stock (other), standing stock or plant density) is a measurement of population per unit land area. It is mostly applied to humans, but sometimes to other living organisms too. It is a key geographical term.Matt RosenberPopulation Density Geography.about.com. March 2, 2011. Retrieved on December 10, 2011. In simple terms, population density refers to the number of people living in an area per square kilometre, or other unit of land area. Biological population densities Population density is population divided by total land area, sometimes including seas and oceans, as appropriate. Low densities may cause an extinction vortex and further reduce fertility. This is called the Allee effect after the scientist who identified it. Examples of the causes of reduced fertility in low population densities are * Increased problems with locating sexual mates * Increased inbreeding Human densities Population density is the number of people pe ...

Census
A census is the procedure of systematically acquiring, recording and calculating information about the members of a given population. This term is used mostly in connection with national population and housing censuses; other common censuses include censuses of agriculture, traditional culture, business, supplies, and traffic censuses. The United Nations (UN) defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory, simultaneity and defined periodicity", and recommends that population censuses be taken at least every ten years. UN recommendations also cover census topics to be collected, official definitions, classifications and other useful information to co-ordinate international practices. The UN's Food and Agriculture Organization (FAO), in turn, defines the census of agriculture as "a statistical operation for collecting, processing and disseminating data on the structure of agriculture, coverin ...

Mediterranean Climate
A Mediterranean climate (also called a dry summer temperate climate ''Cs'') is a temperate climate sub-type, generally characterized by warm, dry summers and mild, fairly wet winters; these weather conditions are typically experienced in the majority of Mediterranean-climate regions and countries, but remain highly dependent on proximity to the ocean, altitude and geographical location. This climate type's name is in reference to the coastal regions of the Mediterranean Sea within the Mediterranean Basin, where this climate type is most prevalent. The "original" Mediterranean zone is a massive area, its western region beginning with the Iberian Peninsula in southwestern Europe and coastal regions of northern Morocco, extending eastwards across southern Europe, the Balkans, and coastal Northern Africa, before reaching a dead-end at the Levant region's coastline. Mediterranean climate zones are typically located along the western coasts of landmasses, between roughly 30 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pacific Fruit Express
Pacific Fruit Express was an American railroad refrigerator car leasing company that at one point was the largest refrigerator car operator in the world. History The company was founded on December 7, 1906, as a joint venture between the Union Pacific and Southern Pacific railroads. It began operation on October 1, 1907, with a fleet of 6,600 refrigerator cars built by the American Car and Foundry Company (ACF). In 1923, the Western Pacific Railroad joined the venture by leasing its own new fleet of 2775 reefers to PFE. They were painted in standard PFE colors with only WP heralds on the cars instead of the paired UP-SP markings. The WP cars were all retired by the late 1950s, among the last wooden reefers in PFE's fleet. WP ended its partnership with PFE in late 1967 and joined Fruit Growers Express instead. PFE's assets were divided between the UP and SP when the company was split on April 1, 1978. It is now a UP subsidiary. On September 1, 2022 Union Pacific closed the f ...

Refrigerator Car
A refrigerator car (or "reefer") is a refrigerated boxcar (U.S.), a piece of railroad rolling stock designed to carry perishable freight at specific temperatures. Refrigerator cars differ from simple insulated boxcars and ventilated boxcars (commonly used for transporting fruit), neither of which are fitted with cooling apparatus. Reefers can be ice- cooled, come equipped with any one of a variety of mechanical refrigeration systems, or utilize carbon dioxide (either as dry ice, or in liquid form) as a cooling agent. Milk cars (and other types of "express" reefers) may or may not include a cooling system, but are equipped with high-speed trucks and other modifications that allow them to travel with passenger trains. History Background: North America After the end of the American Civil War, Chicago, Illinois emerged as a major railway center for the distribution of livestock raised on the Great Plains to Eastern markets. Transporting the animals to market required herds to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice House (building)
An ice house, or icehouse, is a building used to store ice throughout the year, commonly used prior to the invention of the refrigerator. Some were underground chambers, usually man-made, close to natural sources of winter ice such as freshwater lakes, but many were buildings with various types of insulation. During the winter, ice and snow would be cut from lakes or rivers, taken into the ice house, and packed with insulation (often straw or sawdust). It would remain frozen for many months, often until the following winter, and could be used as a source of ice during the summer months. The main application of the ice was the storage of foods, but it could also be used simply to cool drinks, or in the preparation of ice-cream and sorbet desserts. During the heyday of the ice trade, a typical commercial ice house would store of ice in a and building. History A cuneiform tablet from c. 1780 BC records the construction of an icehouse by Zimri-Lim, the King of Mari, in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
