Loch Morar

Loch Morar is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Loch Morar rather than just read about it. In short: Loch Morar (Scottish Gaelic: Loch Mòrair) is a freshwater loch in the Rough Bounds of Lochaber, Highland, Scotland. It is the fifth-largest loch by surface area in Scotland, at 26.7 km2 (10.3 sq mi), and the deepest freshwater body in the British Isles with a maximum depth of 310 m (1,017 ft).

Key takeaways

  • Loch Morar belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Loch Morar to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Loch Morar from memory before moving on to harder problems.

Reference excerpt

Loch Morar (Scottish Gaelic: Loch Mòrair) is a freshwater loch in the Rough Bounds of Lochaber, Highland, Scotland. It is the fifth-largest loch by surface area in Scotland, at 26.7 km2 (10.3 sq mi), and the deepest freshwater body in the British Isles with a maximum depth of 310 m (1,017 ft). The loch was created by glacial action around 10,000 years ago, and has a surface elevation of 9 metres (30 ft) above sea level. It separates the traditional district of North Morar (which contains the village of Morar), from Arisaig and Moidart.

Geography

Loch Morar is 18.8 kilometres (11.7 mi) long, has a surface area of 26.7 km2 (10.3 sq mi), and is the deepest freshwater body in the British Isles with a maximum depth of 310 m (1,017 ft). In 1910, John Murray and Laurence Pullar found it to have a mean depth of 87 metres (284 ft) and a total volume of 2.3073 cubic kilometres (81,482,000,000 ft3) during their survey of Scottish lochs. The bottom is deepened below the United Kingdom Continental Shelf, and until 1943, when a depth of 324 metres (1,063 ft) was observed in the Inner Sound, it was believed to be the deepest water in the United Kingdom. The surface of the loch is 9 metres (30 ft) above sea level.. The lake is the deepest, situated on an island in Europe. The water of the loch is clear and oligotrophic, with a minimal intake of nutrients, making it a Site of Special Scientific Interest (SSSI). The main inflow is the River Meoble on the southern side, which drains from Loch Beoraid, although there are three other major inflows at the eastern end of the loch and a stream draining a complex of lochans to the north-west of Loch Morar. The outflow is the River Morar at the western end, which at a few hundred metres long is one of the shortest rivers in the British Isles. At the shallower western end of the loch, there are a number of sizeable forested islands. At the western end of the loch is the village of Morar, which is between Arisaig and Mallaig on the coastal A830 road. The settlements of Bracorina and Bracara are located along the northern shore of the loch, but there is no road along the southern shore. Tarbet, on the shore of Loch Nevis, is a short distance from Loch Morar.

Folklore

According to the posthumously published dictionary of the Scottish Gaelic language collected by Fr. Allan MacDonald (1859–1905), "Loch Morar is said to be blessed by St. Columba and is called (Scottish Gaelic: Tobar Chaluim Chille), 'St. Columba's Well'. It is safe to drink its water though in the greatest heat and perspiration. It does not freeze. The only ice seen about it is at the foot of the mountain streams flowing into it." In relation to Loch Morar's traditional veneration as a holy well, MacDonald also collected, "a story of a young woman who had lost her hair which grew again after she had bathed her head in the Loch." In common with Loch Ness, occasional reports of large unidentified creatures in the loch's waters are made. The loch monster has been dubbed Mòrag.

History

The island in Loch Morar known as Eilean Bàn was traditionally used by the local population as grazing for their cattle herds and was, until trees began being planted in the 19th-century, completely bare of the "dense, barely penetrable growth of timber", that covers the island today. The same island was briefly the location first of a Mass stone and then of an illegal and clandestine Catholic minor seminary founded by Bishop James Gordon, until the Jacobite rising of 1715 forced its closure and eventual reopening at Scalan in Glenlivet. Even long afterwards, Eilean Bàn remained a secret chapel and library for Bishop Gordon's successors. According to Strathglass historian Flora Forbes, however, "a Catholic chapel at this time anywhere throughout the Highlands was usually a barn-like structure, with no windows and a mud floor." After the Battle of Culloden, a combined force of Royal Navy sailors under the command of Captain John Fergussone of HMS Furnace and Captain Duff of HMS Terror and troops from the Campbell of Argyll Militia portaged over nine miles of uncharted, rough, and previously thought to be impassable terrain. They were seeking to capture Bishop Hugh MacDonald, the underground Roman Catholic Vicar General of the Highland District, and high-ranking local Jacobite Army veterans, mainly from Clan Donald, who were correctly suspected of meeting together at the library, former seminary, and Catholic chapel on Eilean Bàn in Loch Morar on 8 June 1746. According to a later report for the Duke of Newcastle, "Upon their arrival at the lake, they immediately spread themselves opposite to the Isle, and in full view of the rebels thereon; who, concluding themselves quite free from danger, fired on our people, at the same time calling them by insulting and opprobrious names, being near enough to be heard. This exultation, however, was quickly at an end; for the King's ships having sailed round to that part of the coast where their boats had little more than a mile to be carried overland to the lake... the rebels immediately lost all courage..." Although the Bishop and the Jacobite leaders managed to quickly row from Eilean Bàn to the loch shore and "escaped into the mountains", according the same report for the Duke of Newcastle, when the government soldiers and sailors arrived upon Eilean Bàn, "They found the before-named Popish bishop's house and chapel; which the sailors quickly gutted and demolished, merrily adorning themselves with the spoils of the chapel. In the scramble, a great many books and papers were tossed about and destroyed." Some of the chapel and seminary foundation stones are still visibly upon Eilean Bàn. Watts has termed the 8 June 1746 book burning and the destruction of most of Bishop MacDonald personal papers, "an irreplaceable loss both for the eighteenth-century Church and the scholar of today."

Worked examples

Example 1 — a first encounter with Loch Morar

Start with the simplest possible case. Write down what Loch Morar claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Loch Morar before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Loch Morar ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Loch Morar

In research
Loch Morar appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Loch Morar in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Loch Morar is common in secondary-school and first-year university syllabi. It links to neighbouring topics Anti-Catholicism in Scotland, Book burnings, Catholic seminaries in Scotland, so understanding it makes those chapters shorter.
In everyday life
Look for Loch Morar outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
