River Seven
The River Seven is a river in North Yorkshire, England. It rises on Danby High Moor, in the middle of the North York Moors, and flows south for about to meet the River Rye, at Brawby. After leaving Danby High Moor, the river flows through Rosedale and passes Rosedale Abbey. In its lower course, it meanders due to interlocking spurs. A number of villages lie along the lower course of the River Seven. Some of these date from the 12th century or earlier, and likely none of them would exist if not for the river. For early settlers, the river may have been the only source of water and fertile land in its flood plains. They relied on the river for fishing, and washing. There are fossils in the sedimentary layers in the river, in the Jurassic layer of rock. Geology The River Seven is a small river, with not much influence on the geology of the area, although over time it has exposed various rock zones. The lacustrine deposits from the last ice age are exposed and visible ...

Normanby, Ryedale
Normanby is a village and civil parish in the Ryedale district of North Yorkshire, England. It is about west of Pickering. It lies on the main road between Malton and Kirkbymoorside. In the old days Normanby had 14 alehouses and was a major stopping point due to its location halfway between Teesside and Humberside. These days Normanby has only one pub and a church. All the houses in Normanby are built along the busy main road. The bridge to the south of the village was built in the mid 18th century and is narrow, so in recent years it has been the scene of many accidents. The bridge takes traffic over the River Seven which runs to the east of the village on its way from Rosedale to the River Rye further south. History The manor of Normanby is mentioned in the Domesday Book in 1086. It was granted by the Crown to St. Mary's Abbey, York. At the dissolution of the monasteries, Henry VIII granted the manor to William Romesden of Longley and Richard Vavasour of Ripon. It was ...

Lower Jurassic
The Early Jurassic Epoch (in chronostratigraphy corresponding to the Lower Jurassic Series) is the earliest of three epochs of the Jurassic Period. The Early Jurassic starts immediately after the Triassic-Jurassic extinction event, 201.3 Ma (million years ago), and ends at the start of the Middle Jurassic 174.1 Ma. Certain rocks of marine origin of this age in Europe are called " Lias" and that name was used for the period, as well, in 19th-century geology. In southern Germany rocks of this age are called Black Jurassic. Origin of the name Lias There are two possible origins for the name Lias: the first reason is it was taken by a geologist from an English quarryman's dialect pronunciation of the word "layers"; secondly, sloops from north Cornish ports such as Bude would sail across the Bristol Channel to the Vale of Glamorgan to load up with rock from coastal limestone quarries (lias limestone from South Wales was used throughout North Devon/North Cornwall as it c ...

Sinnington
Sinnington is a village and civil parish in the Ryedale district of the county of North Yorkshire, England. It is located on the southern boundary of the North York Moors National Park. According to the 2001 UK census, the parish has a total population of 318 people living in 148 households, reduced to a population of 287, at the 2011 Census. The nineteenth century agricultural writer, William Marshall, was born here in 1745. The village was formerly served by a railway station on the Gilling and Pickering (G&P) railway line which opened in 1875 and closed on 31 January 1953 for both passengers and freight. Typical of the area are the medieval cruck-built longhouses of Sinnington. These were constructed as single storey combined dwelling and beast houses and made of the local Jurassic limestone. Originally they had ling thatched roofs, but they were mostly re-roofed in the 19th century with grey slate or red pantiles. All Saints' Church has in its fabric an ...

Appleton-le-Moors
Appleton-le-Moors is a village and civil parish in the Ryedale district of North Yorkshire, England. According to the 2001 census it had a population of 183, reducing to 164 in the 2011 census. Historically part of the North Riding of Yorkshire, the village is in the North York Moors National Park, and is near to Pickering and Kirkbymoorside. This ancient village is recorded in the ''Domesday Book'' and retains its classic mediaeval layout. It is a site of archaeological interest, being a rich source of finds such as flint tools, Roman coins and a mediaeval oven. It is particularly noted for its exceptionally fine 19th century church which has earned the description "the little gem of moorland churches" and is Grade I listed. It was designed by the architect J.L. Pearson in French Gothic style with elaborate decoration, a tower surmounted with a spire, and a beautiful west-facing rose window of the 10-part (i.e. botanical) design similar to the White Rose of York, with stai ...

Cropton
Cropton is a village and civil parish in the Ryedale district of North Yorkshire, England. It is on the border of the North York Moors National Park, north-west of Pickering. History The village is mentioned in the Domesday Book as having three ploughlands, but it does not list any inhabitants. The name of the village derives from Old English (''cropp tūn''), which means a swelling, mound or hill with a farmstead, settlement or village. At the 2001 census, the parish (including Aislaby) had a population of 354, decreasing to 321 (including Stape) at the 2011 Census. The Great Yorkshire Brewery, a microbrewery, is located to the rear of the New Inn on the edge of the village. The owners of the pub started brewing their own beer in 1984, though beer had been brewed in the village as far back as 1613. To the rear of the brewery is the site of a Motte-and-bailey castle, known as the Round Hill, which is scheduled ancient monument. Just outside the village and to the north, is ...

Gauging Station
A stream gauge, streamgage or stream gauging station is a location used by hydrologists or environmental scientists to monitor and test terrestrial bodies of water. Hydrometric measurements of water level surface elevation (" stage") and/or volumetric discharge (flow) are generally taken and observations of biota and water quality may also be made. The locations of gauging stations are often found on topographical maps. Some gauging stations are highly automated and may include telemetry capability transmitted to a central data logging facility. Measurement equipment Automated direct measurement of streamflow discharge is difficult at present. In place of the direct measurement of streamflow discharge, one or more surrogate measurements can be used to produce discharge values. In the majority of cases, a stage (the elevation of the water surface) measurement is used as the surrogate. Low gradient (or shallow-sloped) streams are highly influenced by variable downstream ...

Catchment
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 but ...

Ironstone
Ironstone is a sedimentary rock, either deposited directly as a ferruginous sediment or created by chemical replacement, that contains a substantial proportion of an iron ore compound from which iron (Fe) can be smelted commercially. Not to be confused with native or telluric iron, which is very rare and found in metallic form, the term ''ironstone'' is customarily restricted to hard, coarsely banded, non-banded, and non-cherty sedimentary rocks of post-Precambrian age. The Precambrian deposits, which have a different origin, are generally known as banded iron formations. The iron minerals comprising ironstones can consist either of oxides, i.e. limonite, hematite, and magnetite; carbonates, i.e. siderite; silicates, i.e. chamosite; or some combination of these minerals.U.S. Bureau of Mines Staff (1996) ''Dictionary of Mining, Mineral, & Related Terms.''

Shales
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable bedding p ...

Oxford Clay
The Oxford Clay (or Oxford Clay Formation) is a Jurassic marine sedimentary rock formation underlying much of southeast England, from as far west as Dorset and as far north as Yorkshire. The Oxford Clay Formation dates to the Jurassic, specifically, the Callovian and Oxfordian ages, and comprises two main facies. The lower facies comprises the Peterborough Member, a fossiliferous organic-rich mudstone. This facies and its rocks are commonly known as lower Oxford Clay. The upper facies comprises the middle Oxford Clay, the Stewartby Member, and the upper Oxford Clay, the Weymouth Member. The upper facies is a fossil poor assemblage of calcareous mudstones. Oxford Clay appears at the surface around Oxford, Peterborough and Weymouth and is exposed in many quarries around these areas. The top of the Lower Oxford Clay shows a lithological change, where fissile shale changes to grey mudstone. The Middle and Upper Oxford Clays differ slightly, as they are separated by an argillaceo ...

Corallian Limestone
The Corallian Group or Corallian Limestone is a geologic group in England. It is predominantly a coralliferous sedimentary rock, laid down in the Oxfordian stage of the Jurassic. It is a hard variety of "coral rag". Building stones from this geological structure tend to be irregular in shape. It is often found close to seams of Portland Limestone (e.g. Abbotsbury in Dorset, England). It is a younger limestone than its near-neighbour, the Oolitic, as found in the Cotswolds, in Gloucestershire. It is laterally equivalent to and interfingers with units of the Ancholme Group. A ridge of Corallian Limestone rises above the Vale of Avon and the Thames Valley in its Oxfordshire stretch. The Oxfordshire Corallian ridge is an escarpment holding back the hanging valley that is the Vale of White Horse and its hardness forced the River Thames to take a wide northern detour, to cut through the low ridge at Oxford. High points along the ridge are Cumnor Hurst and Wytham Hill. The outcrop kno ...
