Salmons Brook
Salmons Brook is a minor tributary of the River Lea, located in the London Borough of Enfield. Etymology Salmons Brook is marked thus on Rocque's map of 1754, probably named from the family of John ''Salemon'' of Edmonton mentioned in 1274. Course The brook rises in Enfield Chase on the borders of the former Enfield Old Park, and flows east close to Trent Park and to Bush Hill where it passes under the New River to enter Edmonton. The brook is culverted under Edmonton Green to emerge at Plevna Road, where it runs alongside of the Pymmes Brook Trail. It skirts the walled Edmonton Federation Jewish Cemetery and the Tottenham Park Cemetery before flowing under Montagu Road to be joined by the culverted Saddlers Mill Stream in an area prone to serious flooding. Running in a westerly direction through wasteland and under the Lea Valley Lines railway it is quickly joined by the outflow of the Deephams Sewage Treatment Works.

River Lea
The River Lea ( ) is in South East England. It originates in Bedfordshire, in the Chiltern Hills, and flows southeast through Hertfordshire, along the Essex border and into Greater London, to meet the River Thames at Bow Creek. It is one of the largest rivers in London and the easternmost major tributary of the Thames. The river's significance as a major east–west barrier and boundary has tended to obscure its importance as north–south trade route. Below Hertford the river has since medieval times had alterations made to make it more navigable for boats between the Thames and eastern Hertfordshire and Essex, known as the Lee Navigation. This stimulated much industry along its banks. The navigable River Stort, the main tributary, joins it at Hoddesdon. While the lower Lea remains somewhat polluted, its upper stretch and tributaries, classified as chalk streams, are a major source of drinking water for London. An artificial waterway known as the New River, opened in 1613, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eley Industrial Estate
Eley Industrial Estate is in Edmonton, London. Bordered by the Angel Road which is part of the A406 road, North Circular Road A406 road, the River Lee Navigation, and the Lea Valley Lines railway line. The estate is named after Eley Brothers who manufactured Cartridge (firearms), firearms cartridges here. Today The estate is now mostly used for warehousing and retail outlets. The former B&I Nathan furniture factory is now used to manufacture the Parker Knoll range of furniture. Coca-Cola are a major employer with a manufacturing plant on the estate. The estate still has some functional brick built factories from the 1950s.Cherry.

Finchley
Finchley () is a large district of north London, England, in the London Borough of Barnet. Finchley is on high ground, north of Charing Cross. Nearby districts include: Golders Green, Muswell Hill, Friern Barnet, Whetstone, Mill Hill and Hendon. It is predominantly a residential suburb, with three town centres: North Finchley, East Finchley and Finchley Church End (Finchley Central). Made up of four wards, the population of Finchley counted 65,812 as of 2011. History Finchley probably means "Finch's clearing" or "finches' clearing" in late Anglo-Saxon; the name was first recorded in the early 13th century. Finchley is not recorded in Domesday Book, but by the 11th century its lands were held by the Bishop of London. In the early medieval period the area was sparsely populated woodland, whose inhabitants supplied pigs and fuel to London. Extensive cultivation began about the time of the Norman conquest. By the 15th and 16th centuries the woods on the eastern side of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watford
Watford () is a town and borough in Hertfordshire, England, 15 miles northwest of Central London, on the River Colne. Initially a small market town, the Grand Junction Canal encouraged the construction of paper-making mills, print works, and breweries. While industry has declined in Watford, its location near London and transport links has attracted several companies to site their headquarters in the town. Cassiobury Park is a public park that was once the manor estate of the Earls of Essex. The town developed next to the River Colne on land belonging to St Albans Abbey. In the 12th century, a charter was granted allowing a market, and the building of St Mary's Church began. The town grew partly due to travellers going to Berkhamsted Castle and the royal palace at Kings Langley. A mansion was built at Cassiobury in the 16th century. This was partly rebuilt in the 17th century and another country house was built at The Grove. The Grand Junction Canal in 1798 and th ...

Anglian Stage
The Anglian Stage is the name used in the British Isles for a middle Pleistocene glaciation. It precedes the Hoxnian Stage and follows the Cromerian Stage in the British Isles. The Anglian Stage is correlated to Marine Isotope Stage 12 (MIS 12), which started about 478,000 years ago and ended about 424,000 years ago. Lisiecki, L.E. (2005Ages of MIS boundaries.

Alluvium
Alluvium (from Latin ''alluvius'', from ''alluere'' 'to wash against') is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not consolidated into solid rock. Sediments deposited underwater, in seas, estuaries, lakes, or ponds, are not described as alluvium. Floodplain alluvium can be highly fertile, and supported some of the earliest human civilizations. Definitions The present consensus is that "alluvium" refers to loose sediments of all types deposited by running water in floodplains or in alluvial fans or related landforms. However, the meaning of the term has varied considerably since it was first defined in the French dictionary of Antoine Furetière, posthumously published in 1690. Drawing upon concepts from Roman law, Furetière defined ''alluvion'' (the F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Till
image:Geschiebemergel.JPG, Closeup of glacial till. Note that the larger grains (pebbles and gravel) in the till are completely surrounded by the matrix of finer material (silt and sand), and this characteristic, known as ''matrix support'', is diagnostic of till. image:Glacial till exposed in roadcut-750px.jpg, Glacial till with tufts of grass Till or glacial till is unsorted glacier, glacial sediment. Till is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines. Till is classified into primary deposits, laid down directly by glaciers, and secondary deposits, reworked by fluvial transport and other processes. Description Till is a form of '' glacial drift'', which is rock material transported by a glacier and deposited directly from the ice or from running water emerging from the ice. It is distinguished from other forms of drift in that it is depos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today, although a third epoch, the Anthropocene, has been proposed but is not yet officially recognised by the ICS). The Quaternary Period is typically defined by the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four successive formations or "orders" ( it, quattro ordini). The term "quaternary" was introduced by Jules Desnoye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Clay
The London Clay Formation is a marine geological formation of Ypresian (early Eocene Epoch, c. 56–49 million years ago) age which crops out in the southeast of England. The London Clay is well known for its fossil content. The fossils from the lower Eocene rocks indicate a moderately warm climate, the tropical or subtropical flora. Though sea levels changed during the deposition of the clay, the habitat was generally a lush forest – perhaps like in Indonesia or East Africa today – bordering a warm, shallow ocean. The London Clay is a stiff bluish clay which becomes brown when weathered and oxidized. Nodular lumps of pyrite are frequently found in the clay layers. Pyrite was produced by microbial activity (sulfate reducing bacteria) during clay sedimentation. Once clay is exposed to atmospheric oxygen, framboidal pyrite with a great specific surface is rapidly oxidized. Pyrite oxidation produces insoluble brown iron oxyhydroxide (FeOOH) and sulfuric acid leading to the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Popigai impact structure, Siberia and in what is now ...

Pymmes Brook
Pymmes Brook is located in North London and named after William Pymme, a local land owner. It is a minor tributary of the River Lea. The brook mostly flows through urban areas and is particularly prone to flooding in its lower reaches. To alleviate the problem the brook has been culverted in many areas. Part of it is a Site of Borough Importance for Nature Conservation, Grade II. Course The source of the brook are underground springs at Hadley Common which are mentioned in reference to the penultimate battle in the Wars of the Roses at the Battle of Barnet. At this point it is known as Monken Mead Brook before flowing in a south-easterly direction to merge with the River Lee Navigation at Tottenham. It flows through East Barnet, where it is joined by a small tributary, the Shirebourne brook before flowing through New Southgate, Arnos Grove, Palmers Green and Edmonton. After flowing through Pymmes Park the brook can be seen at Fore Street, Edmonton before it flows undergr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
