Loch Arkaig

Loch Arkaig 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 Arkaig rather than just read about it. In short: Loch Arkaig (Scottish Gaelic: Loch Airceig) is a body of freshwater in Lochaber, Scotland, to the west of the Great Glen. It is approximately 12 miles (19 kilometres) in length and lies 140 feet (43 metres) above sea level, and the maximum depth is around 300 feet (90 metres).

Key takeaways

  • Loch Arkaig 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 Arkaig to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Loch Arkaig from memory before moving on to harder problems.

Reference excerpt

Loch Arkaig (Scottish Gaelic: Loch Airceig) is a body of freshwater in Lochaber, Scotland, to the west of the Great Glen. It is approximately 12 miles (19 kilometres) in length and lies 140 feet (43 metres) above sea level, and the maximum depth is around 300 feet (90 metres). The loch is among the last remaining fragments of the Caledonian pinewood, which is native to the UK. The main tributaries are the Dessarry and the Pean, which flow through the glens of the same names, falling into the loch at the extreme west end, by the settlement of Strathan. The mountains of Lochaber lie to the north, and the Forest of Locheil to the south. The outflow is through the River Arkaig at the extreme southeast of the loch, which flows eastwards 1+3⁄8 miles (2.2 kilometres) to Loch Lochy, passing Achnacarry. Two small islands lie at the eastern end of the loch, the larger of which, Island Columbkill, or Eilean Loch Airceig, is the site of a ruined chapel dedicated to St Columba which is the former burial ground of the Camerons of Locheil. A road from the Great Glen follows the north shore of the loch to Strathan where paths lead on to Knoydart, Glenfinnan and Loch Morar.

In 1746, Jacobite funds were said to have been hidden here (see Loch Arkaig treasure). In common with a number of other Scottish lochs, Loch Arkaig was at one time supposed to be the home of a water horse. James Harris, 3rd Earl of Malmesbury and twice foreign minister during Queen Victoria's reign, recorded in his Memoirs of an Ex-Minister:

"October 3rd, 1857. This morning my stalker and his boy gave me an account of a mysterious creature, which they say exists in Loch Arkaig, and which they call the Lake-Horse. It is the same animal of which one has occasionally read accounts in newspapers as having been seen in the Highland lochs, and of the existence of which in Loch Assynt the late Lord Ellesmere wrote an interesting article, but hitherto the story has always been looked upon as fabulous. I am now, however, nearly persuaded of its truth. My stalker, John Stuart, at Achnacarry, has seen it twice, and both times at sunrise on a bright sunny day, when there was not a ripple on the water. The creature was basking on the surface; he only saw the head and hind quarters, proving that its back was hollow, which is not the shape of any fish or of a seal. Its head resembled that of a horse.... The Highlanders are very superstitious about this creature. They are convinced that there is never more than one in existence at the same time, and I believe they think it has something diabolical in its nature, for when I said I wished I could get within shot of it, my stalker observed very gravely: 'Perhaps your Lordship's gun would miss fire.'"

Worked examples

Example 1 — a first encounter with Loch Arkaig

Start with the simplest possible case. Write down what Loch Arkaig 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 Arkaig 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 Arkaig 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 Arkaig

In research
Loch Arkaig 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 Arkaig 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 Arkaig is common in secondary-school and first-year university syllabi. It links to neighbouring topics Freshwater lochs of Scotland, Lochaber, Lochs of Highland (council area), so understanding it makes those chapters shorter.
In everyday life
Look for Loch Arkaig 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.
