Welsh Basin

The Welsh Basin was a northeast-southwest aligned back-arc depositional basin during the Cambrian, Ordovician and Silurian periods during which a considerable thickness of marine sediments was laid down in the area. To the southeast lay the Midland Platform (a part of the micro-continent of Avalonia) and to the northwest, within the Iapetus Ocean, through what is now Ireland and the Lake District, was an island arc; a northeast-southwest aligned Irish Sea landmass which was associated with volcanic activity. Examination of the sediments and associated fossils allows the deeper centre of the basin to be distinguished from shallower 'platform' areas along its southeastern margins. From the middle Silurian onwards, collision of Avalonia with the more northerly continent of Laurentia occurred giving rise to the Caledonian Orogeny. The inversion of the basin occurred at that time i.e. its uplift and deformation.

The southeastern limit of the Welsh Basin can be defined as the Welsh Borderland Fault Zone comprising the Pontesford-Linley Fault and Church Stretton Fault which stretch from Pembrokeshire to Shropshire and, in the northwest, the Menai Strait Fault Zone. Its extent to the southwest and northeast is uncertain as these areas are cloaked by more recent rocks.

Welsh pig

The Welsh is a breed of domestic pig native to Wales. It is a large white breed known for its hardiness in outdoor (extensive) farming and its long, pear-shaped body. The breed was first mentioned in the 1870s, and is the third most common sire in the U.K. after the Large White and British Landrace. The Welsh pig is not exported to many countries around the world despite the fact that they can produce substantially good bacon.

History

The Welsh Pig comes from various Welsh towns. In Mid Wales, Montgomery and Cardigan and also in Carmarthen and Pembroke. The earliest reference to the Welsh was in the 1870s and it originated from the Wild Boar like its similar breeds. After the Second World War, the Welsh pig became a great source for prosperity and the numbers grew by quite a reasonable amount, ultimately ending in 1,363 boars in the UK by 1954 and 3,736 sows bred in 1953. This breed of pig became incredibly popular in the mid-20th century and became a crucial breed for the pig industry.

Dock (maritime)

A dock (from Dutch dok) is either the area of water between or next to a human-made structure or group of structures involved in the handling of boats or ships, usually on or close to a shore, or the structures themselves. The exact meaning varies among different variants of the English language. "Dock" may also refer to a dockyard or shipyard where the loading, unloading, building, or repairing of ships occurs.

History

The earliest known docks were those discovered in Wadi al-Jarf, an ancient Egyptian harbor dating from 2500 BCE located on the Red Sea coast. Archaeologists also discovered anchors and storage jars near the site. A dock from Lothal in India dates from 2400 BCE and was located away from the main current to avoid deposition of silt. Modern oceanographers have observed that the Harappans must have possessed great knowledge relating to tides in order to build such a dock on the ever-shifting course of the Sabarmati, as well as exemplary hydrography and maritime engineering. This was the earliest known dock found in the world, equipped to berth and service ships. It is speculated that Lothal engineers studied tidal movements, and their effects on brick-built structures, since the walls are of kiln-burnt bricks. This knowledge also enabled them to select Lothal's location in the first place, as the Gulf of Khambhat has the highest tidal amplitude and ships can be sluiced through flow tides in the river estuary. The engineers built a trapezoidal structure, with north-south arms of average 21.8 metres (71.5 ft), and east-west arms of 37 metres (121 ft).

Franconia Notch State Park is located in the White Mountains in northern New Hampshire, United States, and straddles 8 miles (13 km) of Interstate 93 as it passes through Franconia Notch, a mountain pass between the Kinsman Range and Franconia Range. Attractions in the state park include the Flume Gorge and visitor center, the Old Man of the Mountain historical site, fishing in Echo Lake and Profile Lake, and miles of hiking, biking and ski trails. The northern part of the park, including Cannon Mountain and Echo and Profile lakes, is in the town of Franconia, and the southern part, including Lonesome Lake and the Flume, is in Lincoln.

The park is home to Cannon Mountain, a state-owned ski resort started in the 1930s. The mountain is named for a rock formation in the shape of a cannon found on the summit, but the "Old Man of the Mountain" formation was by far the more famous; it collapsed in May 2003. Cannon is also famous for being one of the most challenging hills in New England. It boasts an aerial tram, which runs year-round, ferrying sightseers to the summit in the summer time and skiers in the winter. At the base of the tramway is the New England Ski Museum, with exhibits on the history of alpine skiing in New England and America.
