Barkway Chalk Pit
Barkway Chalk Pit is a small (0.3 hectare) nature reserve in Barkway in North Hertfordshire. It was managed by the Herts and Middlesex Wildlife Trust (HMWT). In February 2016 HMWT announced that three sites, Barkway Chalk Pit, Hill End Pit and Pryor's Wood, which HMWT managed on behalf of their owner, North Hertfordshire District Council, were to return to Council management as the Trust was no longer able to meet the cost. The site has been designated a Regionally important geological site (RIGS) by the Hertfordshire RIGS Group. It exposes a chalk block which is out of position because it was displaced by the Anglian stage, Anglian ice sheet which covered Hertfordshire around 450,000 years ago. The vegetation is chalk scrub, and there are many species of birds, including yellowhammer, spotted flycatcher, blue tit and tawny owl. The entrance to the site is a short distance along an unnamed road which goes north from the junction of The Joint and Royston Road. References

Herts And Middlesex Wildlife Trust
Herts and Middlesex Wildlife Trust manages over 40 nature reserves covering nearly north of London, in Hertfordshire and the historic county of Middlesex, part of which is divided between the London boroughs of Barnet, Enfield, Harrow and Hillingdon. It has over 21,000 members, and is one of 46 Wildlife Trusts across the UK. It is a Registered Charity, with its Registered Office in St Albans, and had an income in the year to 31 March 2014 of over £1.5 million. The trust's activities include managing nature reserves, advising landowners on how to manage their land for wildlife, commenting on planning applications, advising planning authorities and campaigning to protect wildlife. The trust also encourages people to be active volunteers helping to maintain nature reserves. The first preparatory meeting of what was to become the trust was held on 16 November 1963, and the Hertfordshire & Middlesex Trust for Nature Conservation was incorporated on 9 October 1964. By 1970 i ...

North Hertfordshire District Council
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography. Etymology The word ''north'' is related to the Old High German ''nord'', both descending from the Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Greek '' boreas'' "north wind, north", which, according to Ovid, was personified as the wind-god Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. Other languages have other derivations. For example, in Lezgian, ''kefer'' can mean ...

Regionally Important Geological Site
Regionally important geological and geomorphological sites (RIGS) (also known as regionally important geological sites or, especially in Wales, regionally important geodiversity sites) are locally designated sites of local, national and regional importance for geodiversity (geology and geomorphology) in the United Kingdom and Isle of Man. RIGS may be designated for their value to Earth Science, and to Earth heritage in general, and may include cultural, educational, historical and aesthetic resources. The concept was introduced by the Nature Conservancy Council's publication ''Earth Science Conservation in Great Britain – A Strategy'' (1990). They are conserved and protected from development as a material consideration through the planning system by the Town and Country Planning Act 1990. They do not have the statutory management protection enjoyed by Sites of Special Scientific Interest (SSSIs) or Areas of Special Scientific Interest (Isle of Man). Local geological sites includ ...

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.

Hertfordshire ( or ; often abbreviated Herts) is one of the home counties in southern England. It borders Bedfordshire and Cambridgeshire to the north, Essex to the east, Greater London to the south, and Buckinghamshire to the west. For government statistical purposes, it forms part of the East of England region. Hertfordshire covers . It derives its name – via the name of the county town of Hertford – from a hart (stag) and a ford, as represented on the county's coat of arms and on the flag. Hertfordshire County Council is based in Hertford, once the main market town and the current county town. The largest settlement is Watford. Since 1903 Letchworth has served as the prototype garden city; Stevenage became the first town to expand under post-war Britain's New Towns Act of 1946. In 2013 Hertfordshire had a population of about 1,140,700, with Hemel Hempstead, Stevenage, Watford and St Albans (the county's only ''city'') each having between 50,000 and 100,000 resi ...

Chalk Pits
Chalk is a soft, white, porous, sedimentary carbonate rock. It is a form of limestone composed of the mineral calcite and originally formed deep under the sea by the compression of microscopic plankton that had settled to the sea floor. Chalk is common throughout Western Europe, where deposits underlie parts of France, and steep cliffs are often seen where they meet the sea in places such as the Dover cliffs on the Kent coast of the English Channel. Chalk is mined for use in industry, such as for quicklime, bricks and builder's putty, and in agriculture, for raising pH in soils with high acidity. It is also used for " blackboard chalk" for writing and drawing on various types of surfaces, although these can also be manufactured from other carbonate-based minerals, or gypsum. Description Chalk is a fine-textured, earthy type of limestone distinguished by its light color, softness, and high porosity. It is composed mostly of tiny fragments of the calcite shells or ...

Geology Of Hertfordshire
The geology of Hertfordshire describes the rocks of the English county of Hertfordshire which are a northern part of the great shallow syncline known as the London Basin. The beds dip in a south-easterly direction towards the syncline's lowest point roughly under the River Thames. The most important formations are the Cretaceous chalks, which are exposed as the high ground in the north and west of the county, and the Cenozoic rocks made up of the Paleocene age Reading beds and Eocene age London Clay that occupies the remaining southern part.Hertfordshire Geological Society The Cretaceous On the northern boundary and just inside the county, at the foot of the chalk Chiltern Hills, near Tring and Ashwell, there is a small strip of exposed Cretaceous Gault Clay and Upper Greensand. At 100 million years old, these are the oldest rocks in the county. Rocks get progressively younger as one moves in a south easterly direction through the county. The lowest layer of the chalk is the ...
