Great Michigan Fire
The Great Michigan Fire was a series of simultaneous forest fires in the state of Michigan in the United States in 1871. They were possibly caused (or at least reinforced) by the same winds that fanned the Great Chicago Fire, the Peshtigo Fire and the Port Huron Fire; some believe lightning or even meteor showers may have started the fires. Several cities, towns and villages, including Alpena, Holland, Manistee, and Port Huron, suffered serious damage or were lost. The concurrent Peshtigo Fire in Wisconsin also destroyed several towns in the Upper Peninsula of Michigan. In 1881, much more than half of "the Thumb" region was burned over by the Thumb Fire, which followed part of the same path as the 1871 fires. Origins In the mid-1830s logging began in Michigan and grew into a significant industry. Michigan was extensively logged for the Eastern white pine, measuring tall and exceeding in diameter, along with the hardwood forests. By 1854, sixteen sawmills were in operation ...

Forest Fire
A wildfire, forest fire, or a bushfire is an unplanned and uncontrolled fire in an area of combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire ( in Australia), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld fire. Some natural forest ecosystems depend on wildfire. Modern forest management often engages in prescribed burns to mitigate fire risk and promote natural forest cycles. However, controlled burns can turn into wildfires by mistake. Wildfires can be classified by cause of ignition, physical properties, combustible material present, and the effect of weather on the fire. Wildfire severity results from a combination of factors such as available fuels, physical setting, and weather. Climatic cycles with wet periods that create substantial fuels, followed by drought and heat, often precede severe wildfires. These cycles have been intensified by climate cha ...

Logging
Logging is the process of cutting, processing, and moving trees to a location for transport. It may include skidder, skidding, on-site processing, and loading of trees or trunk (botany), logs onto logging truck, trucksSociety of American Foresters, 1998. Dictionary of Forestry. or flatcar#Skeleton car, skeleton cars. In forestry, the term logging is sometimes used narrowly to describe the logistics of moving wood from the stump to somewhere outside the forest, usually a sawmill or a lumber yard. In common usage, however, the term may cover a range of forestry or silviculture activities. Logging is the beginning of a supply chain that provides raw material for many products societies worldwide use for housing, construction, energy, and consumer paper products.

Meteorite
A meteorite is a rock (geology), rock that originated in outer space and has fallen to the surface of a planet or Natural satellite, moon. When the original object enters the atmosphere, various factors such as friction, pressure, and chemical interactions with the atmospheric gases cause it to heat up and radiate energy. It then becomes a meteor and forms a Meteoroid#Fireball, fireball, also known as a shooting star; astronomers call the brightest examples "Bolide#Astronomy, bolides". Once it settles on the larger body's surface, the meteor becomes a meteorite. Meteorites vary greatly in size. For geologists, a bolide is a meteorite large enough to create an impact crater. Meteorites that are recovered after being observed as they transit the atmosphere and impact event, impact Earth are called meteorite falls. All others are known as meteorite finds. Meteorites have traditionally been divided into three broad categories: stony meteorites that are rocks, mainly composed of sil ...

Methane
Methane ( , ) is a chemical compound with the chemical formula (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas. The abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it is difficult because it is a gas at standard temperature and pressure. In the Earth's atmosphere methane is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. Methane is an Organic chemistry, organic Organic compound, compound, and among the simplest of organic compounds. Methane is also a hydrocarbon. Naturally occurring methane is found both below ground and under the seafloor and is formed by both geological and biological processes. The largest reservoir of methane is under the seafloor in the form of methane clathrates. When methane reaches the surface and the Atmosphere of Earth, atmosphere, it is known as atmospheric methane. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comet Biela
Biela's Comet or Comet Biela (official designation: 3D/Biela) was a periodic Jupiter-family comet first recorded in 1772 by Montaigne and Messier and finally identified as periodic in 1826 by Wilhelm von Biela. It was subsequently observed to split in two and has not been seen since 1852. As a result, it is currently considered to have been destroyed, although remnants have survived for some time as a meteor shower, the Andromedids which may show increased activity in 2023. Discovery The comet was first recorded on 8 March 1772 by Jacques Leibax Montaigne; during the same apparition it was independently discovered by Charles Messier. It was also recorded in 1805 by Jean-Louis Pons, but was not recognized as the same object. Around 9 December 1805 comet Biela passed about from Earth. After the 1805 apparition a number of attempts were made by Gauss (1806) and Bessel (1806) to calculate a definitive orbit. Gauss and Olbers both noted a similarity between the 1805 and 1772 ...

Lumberjack
Lumberjack is a mostly North American term for workers in the logging industry who perform the initial harvesting and transport of trees. The term usually refers to loggers in the era before 1945 in the United States, when trees were felled using hand tools and dragged by oxen to rivers. The work was difficult, dangerous, intermittent, low-paying, and involved living in primitive conditions. However, the men built a traditional culture that celebrated strength, masculinity, confrontation with danger, and resistance to modernization. Term The term lumberjack is of Canadian derivation. The first attested use of the term combining its two components comes from an 1831 letter to the Cobourg, Ontario, ''Star and General Advertiser'' in the following passage: "my misfortunes have been brought upon me chiefly by an incorrigible, though perhaps useful, race of mortals called lumberjacks, whom, however, I would name the Cossacks of Upper Canada, who, having been reared among the ...

Peshtigo Fire
The Peshtigo fire was a large forest fire on October 8, 1871, in northeastern Wisconsin, United States, including much of the southern half of the Door Peninsula and adjacent parts of the Upper Peninsula of Michigan. The largest community in the affected area was Peshtigo, Wisconsin, which had a population of approximately 1,700 residents. The fire burned about and is the deadliest wildfire in recorded history, with the number of deaths estimated between 1,500 and 2,500. The exact number of deaths is debated. Data from mass graves, both those already exhumed and those still being discovered, show that the death toll of the blaze was most likely greater than the 1889 Johnstown flood death toll of 2,200 people or more. Occurring on the same day as the more famous Great Chicago Fire, the Peshtigo fire has been largely forgotten, even though it killed at least five times as many people. Nonetheless, several cities in Michigan, including Holland and Manistee (across Lake Mic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Slash (logging)
In forestry, slash, or slashings are coarse and fine woody debris generated during logging operations or through wind, snow or other natural forest disturbances. Slash generated during logging operations may increase fire hazard, and some North American states have passed laws requiring the treatment of logging slash. Logging slash can be chipped and used (for example) in the production of electricity or heat in cogeneration power-plants, or simply burned onsite. Where logging takes place on soft ground, loggers can use the branches and tops of trees as part of the timber-harvesting process to provide a track for forest machines. Using slash in this manner reduces ground damage. See also * Coarse woody debris * Lignocellulosic biomass Lignocellulose refers to plant dry matter (biomass), so called lignocellulosic biomass. It is the most abundantly available raw material on the Earth for the production of biofuels. It is composed of two kinds of carbohydrate polymers, cel ...
