History Of Ajax, Ontario
The town of Ajax, Ontario in Canada evolved out of the Defence Industries Limited Pickering Works munitions plant built during the World War II, but its history begins much earlier. The indigenous peoples in Canada, indigenous peoples were active in the watersheds of the Duffins Creek and the Carruthers Creek (Canada), Carruthers Creek since the Archaic period (North America), Archaic period (7000–1000 BCE), although they did not build any major settlements in the area. After the Conquest of New France (1758–1760), British conquest of New France in 1760, the area became part of the Pickering Township. The conversion of a local trail into the Ontario Highway 2, Kingston Road in 1799 contributed to increased settlement in area. In the first half of the 19th century, the Pickering Village, now a neighbourhood in Ajax, evolved as the major population centre of the Township, supported by a timber and agricultural boom. In the mid-19th century, Audley, Ontario, Audley, a smaller comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ajax, Ontario
Ajax (; 2021 Canadian census, 2021 population: 126,666) is a town in Regional Municipality of Durham, Durham Region in Southern Ontario, Canada, located in the eastern part of the Greater Toronto Area. The town is named for , a Royal Navy cruiser that served in the Second World War. It is approximately east of Toronto on the shores of Lake Ontario and is bordered by the City of Pickering, Ontario, Pickering to the west and north, and the Town of Whitby, Ontario, Whitby to the east. History The indigenous peoples in Canada, indigenous peoples were active in the watersheds of the Duffins Creek and the Carruthers Creek (Canada), Carruthers Creek since the Archaic period (North America), Archaic period (7000-1000 BCE), although they did not build any major settlements in the area, presumably because of the poor navigability of these streams. In 1760, French Canadians, French Sulpician missionaries from Ganatsekwyagon reached Duffins Creek area, but did not settle there. After the ...

University Of Toronto Ajax Division
The Ajax Division was the University of Toronto's campus in Ajax, an unincorporated community (now a town) within the Pickering Township of Ontario, Canada. It was located at the site of the defunct Defence Industries Limited Pickering Works munitions plant, which was leased by the federal government to the University for a nominal rent. The Ajax Division was set up to meet the increasing demand for engineering education from World War II veterans returning from the war theatre in Europe. The University's downtown Toronto campus accommodated 400 veterans who had completed at least 29 months of active service; the Ajax campus accommodated the rest of the engineering students, both veterans and non-veterans. The campus was active between January 1946 and April 1949, with approximately 6,000 students attending classes there. At its peak, during 1946-47, it had 3,312 students and 210 instructors. By 1949, the university had built new engineering facilities in downtown Toronto, and deci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodland Period
In the classification of :category:Archaeological cultures of North America, archaeological cultures of North America, the Woodland period of North American pre-Columbian cultures spanned a period from roughly 1000 Common Era, BCE to European contact in the eastern part of North America, with some archaeologists distinguishing the Mississippian period, from 1000 CE to European contact as a separate period. The term "Woodland Period" was introduced in the 1930s as a generic term for prehistoric, prehistoric sites falling between the Archaic period in the Americas, Archaic hunter-gatherers and the agriculturalist Mississippian cultures. The Eastern Woodlands cultural region covers what is now eastern Canada south of the Subarctic region, the Eastern United States, along to the Gulf of Mexico. This period is variously considered a developmental stage, a time period, a suite of technological adaptations or "traits", and a "family tree" of cultures related to earlier Archaic cultures. ...

Lake Ontario
Lake Ontario is one of the five Great Lakes of North America. It is bounded on the north, west, and southwest by the Canadian province of Ontario, and on the south and east by the U.S. state of New York. The Canada–United States border spans the centre of the lake. The Canadian cities of Toronto, Kingston, Mississauga, and Hamilton are located on the lake's northern and western shorelines, while the American city of Rochester is located on the south shore. In the Huron language, the name means "great lake". Its primary inlet is the Niagara River from Lake Erie. The last in the Great Lakes chain, Lake Ontario serves as the outlet to the Atlantic Ocean via the Saint Lawrence River, comprising the eastern end of the Saint Lawrence Seaway. The Moses-Saunders Power Dam regulates the water level of the lake. Geography Lake Ontario is the easternmost of the Great Lakes and the smallest in surface area (7,340 sq mi, 18,960 km2), although it exceeds Lake Eri ...

Lithic Flake
In archaeology, a lithic flake is a "portion of rock removed from an objective piece by percussion or pressure,"Andrefsky, W. (2005) ''Lithics: Macroscopic Approaches to Analysis''. 2d Ed. Cambridge, Cambridge University Press and may also be referred to as simply a ''flake'', or collectively as debitage. The objective piece, or the rock being reduced by the removal of flakes, is known as a core.Andrefsky, W. (2005) ''Lithics: Macroscopic Approaches to Analysis''. 2d Ed. Cambridge, Cambridge University Press Once the proper tool stone has been selected, a percussor or pressure flaker (e.g., an antler tine) is used to direct a sharp blow, or apply sufficient force, respectively, to the surface of the stone, often on the edge of the piece. The energy of this blow propagates through the material, often ( but not always) producing a Hertzian cone of force which causes the rock to fracture in a controllable fashion. Since cores are often struck on an edge with a suitable angle (<90°) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flint
Flint, occasionally flintstone, is a sedimentary cryptocrystalline form of the mineral quartz, categorized as the variety of chert that occurs in chalk or marly limestone. Flint was widely used historically to make stone tools and start fires. It occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones.''The Flints from Portsdown Hill'' Inside the nodule, flint is usually dark grey, black, green, white or brown in colour, and often has a glassy or waxy appearance. A thin layer on the outside of the nodules is usually different in colour, typically white and rough in texture. The nodules can often be found along s and |
Chert
Chert () is a hard, fine-grained sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO2). Chert is characteristically of biological origin, but may also occur inorganically as a precipitation (chemistry), chemical precipitate or a diagenesis, diagenetic replacement, as in petrified wood. Chert is typically composed of the petrified remains of siliceous ooze, the biogenic sediment that covers large areas of the deep ocean floor, and which contains the silicon skeletal remains of diatoms, Dictyochales, silicoflagellates, and radiolarians. Precambrian cherts are notable for the presence of fossil cyanobacteria. In addition to Micropaleontology, microfossils, chert occasionally contains macrofossils. However, some chert is devoid of any fossils. Chert varies greatly in color (from white to black), but most often manifests as gray, brown, grayish brown and light green to rusty redW.L.

Projectile Point
In North American archaeological terminology, a projectile point is an object that was hafted to a weapon that was capable of being thrown or projected, such as a javelin, dart, or arrow. They are thus different from weapons presumed to have been kept in the hand, such as knives, spears, axes, hammers, and maces. Stone tools, including projectile points, can survive for long periods, were often lost or discarded, and are relatively plentiful, especially at archaeological sites. They provide useful clues to the human past, including prehistoric trade. A distinctive form of point, identified though lithic analysis of the way it was made, is often a key diagnostic factor in identifying an archaeological industry or culture. Scientific techniques exist to track the specific kinds of rock or minerals that were used to make stone tools in various regions back to their original sources. As well as stone, projectile points were also made of worked wood, bone, antler, horn, or ivory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archaeological Site
An archaeological site is a place (or group of physical sites) in which evidence of past activity is preserved (either prehistoric or historic or contemporary), and which has been, or may be, investigated using the discipline of archaeology and represents a part of the archaeological record. Sites may range from those with few or no remains visible above ground, to buildings and other structures still in use. Beyond this, the definition and geographical extent of a "site" can vary widely, depending on the period studied and the theoretical approach of the archaeologist. Geographical extent It is almost invariably difficult to delimit a site. It is sometimes taken to indicate a settlement of some sort although the archaeologist must also define the limits of human activity around the settlement. Any episode of deposition such as a hoard or burial can form a site as well. Development-led archaeology undertaken as cultural resources management has the disadvantage (or the ben ...
