Berwickshire in the context of "Siccar Point"

An unconformity is a buried erosional or non-depositional surface separating two rock masses or strata of different ages, indicating that sediment deposition was not continuous. In general, the older layer was exposed to erosion for an interval of time before deposition of the younger layer, but the term is used to describe any break in the sedimentary geologic record. The significance of angular unconformity (see below) was shown by James Hutton, who found examples of Hutton's Unconformity at Jedburgh in 1787 and at Siccar Point in Berwickshire in 1788, both in Scotland.

The rocks above an unconformity are younger than the rocks beneath (unless the sequence has been overturned). An unconformity represents time during which no sediments were preserved in a region or were subsequently eroded before the next deposition. The local record for that time interval is missing and geologists must use other clues to discover that part of the geologic history of that area. The interval of geologic time not represented is called a hiatus. It is a kind of relative dating.

Marshall Meadows Bay is a small bay located on the Northumberland coast, England, 2+1⁄2 miles (4 kilometres) north of Berwick-upon-Tweed Just to the north of the bay lies the Anglo-Scottish border and the northernmost point of England. Across the border in Scotland is the county of Berwickshire in the Borders region.

The hamlet of Marshall Meadows lies to the west of the bay, and is the most northerly inhabited place in England. The Marshall Meadows Manor House Hotel is here, along with a farm and a caravan site. There is a disused tunnel from the caravan site to the bay below, and there is a small cave 300 m (1,000 ft) north of this tunnel, plus another small cave just around the corner of Marshall Meadows Point. Nearby is the A1 trunk road and the East Coast Main Line railway.

Roxburghshire or the County of Roxburgh (Scottish Gaelic: Siorrachd Rosbroig) is a historic county and registration county in the Southern Uplands of Scotland. It borders Dumfriesshire to the west, Selkirkshire and Midlothian to the northwest, and Berwickshire to the north. To the southwest it borders Cumberland and to the southeast Northumberland, both in England.

It was named after the Royal Burgh of Roxburgh, a town which declined markedly in the 15th century and is no longer in existence. Latterly, the county town of Roxburghshire was Jedburgh.

Robert Hay (6 January 1799 – 4 November 1863) was a Scottish traveller, antiquarian, and early Egyptologist. He was born in Duns Castle, Berwickshire. During his service in the Royal Navy he visited Alexandria, Egypt, in 1818.

In 1824 he met Joseph Bonomi in Rome, whom he hired as an artist and who accompanied Hay to Egypt. They stayed in Egypt from November 1824 until 1828, and 1829 to 1834, recording monuments and inscriptions, and making a large number of architectural plans. His manuscripts are now primarily in the British Library, and many of his plaster casts in the British Museum.

Bernicia (Old English: Bernice, Beornice) was an Anglo-Saxon kingdom established by Anglian settlers of the 6th century in what is now southeastern Scotland and North East England.

The Anglian territory of Bernicia was approximately equivalent to the modern English counties of Northumberland, Tyne and Wear, and Durham, as well as the Scottish counties of Berwickshire and East Lothian, stretching from the Forth to the Tees. In the early 7th century, it merged with its southern neighbour, Deira, to form the kingdom of Northumbria, and its borders subsequently expanded considerably.

The Scottish Borders is one of 32 council areas of Scotland. It is bordered by West Lothian, Edinburgh, Midlothian, and East Lothian to the north, the North Sea to the east, Dumfries and Galloway to the south-west, South Lanarkshire to the west, and the English ceremonial counties of Cumbria and Northumberland to the south. The largest settlement is Galashiels, and the administrative centre is Newtown St Boswells.

The term "Scottish Borders" is also used for the areas of southern Scotland and northern England that bound the Anglo-Scottish border, namely Dumfries and Galloway, Scottish Borders, Northumberland, and Cumbria. The council area occupies approximately the same area as the historic shires of Berwickshire, Peeblesshire, Roxburghshire, and Selkirkshire.

The Archdiocese of St Andrews (originally the Diocese of St Andrews) was a territorial episcopal jurisdiction of the Catholic Church in early modern and medieval Scotland. It was the largest, most populous and wealthiest diocese of the medieval Scottish Catholic church, with territory in eastern Scotland stretching from Berwickshire and the Anglo-Scottish border to Aberdeenshire.

Although not an archdiocese until 1472, St Andrews was recognised as the chief see of the Scottish church from at least the 11th century. It came to be one of two archdioceses of the Scottish church, from the early 16th century having the bishoprics of Aberdeen, Brechin, Caithness, Dunblane, Dunkeld, Moray, Orkney and Ross as suffragans.

The national nature reserves (NNRs) of Scotland are areas of land or water designated under the Wildlife and Countryside Act 1981 as containing habitats and species of national importance. National nature reserves can be owned by public, private, community or voluntary organisations but must be managed to conserve their important habitats and species, as well as providing opportunities for the public to enjoy and engage with nature. There are currently 43 NNRs in Scotland, which cover 154,250 hectares (1,542.5 km), or less than 1.5% of the land area of Scotland. They range in size from Corrieshalloch Gorge at 7 ha to Mar Lodge Estate, which covers 29,324 ha.

National nature reserve status is an accolade awarded to the best nature reserves in Scotland, and the selected sites provide examples of nationally or internationally important species and habitats. NNRs are intended to showcase Scotland's nature, and as well as being well managed for wildlife they must be managed to provide opportunities for the public to visit and enjoy them. NNRs therefore generally have facilities such as visitor centres and trails to allow visitors to explore and understand the habitats or wildlife they contain. 19 of the reserves NNRs have IUCN Category II (national park) status, including, Glen Affric, Rùm, Abernethy Forest and the Great Trossachs Forest. There are no reserves with this status in England, Wales or Northern Ireland. This is mainly due to Scotland's natural habitats being more intact than in the rest of the UK.
