Mount Lidgbird

Mount Lidgbird is a earth 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 Mount Lidgbird rather than just read about it. In short: Mount Lidgbird, also Mount Ledgbird and Big Hill, is located in the southern section of Lord Howe Island, just north of Mount Gower, from which it is separated by the saddle at the head of Erskine Valley, and has its peak at 777 metres (2,549 ft) above sea level. The trek to the summit is for expert climbers only.

Key takeaways

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

Reference excerpt

Mount Lidgbird, also Mount Ledgbird and Big Hill, is located in the southern section of Lord Howe Island, just north of Mount Gower, from which it is separated by the saddle at the head of Erskine Valley, and has its peak at 777 metres (2,549 ft) above sea level. The trek to the summit is for expert climbers only. Ropes are needed to scale the cliffs and slippery, steep terrain. In comparison, Mount Gower is an easy hike. Halfway up the mountain is Goat House Cave, a former shelter for 19th-century Kentia palm gatherers. From this spot, visitors can see nesting masked boobies and numerous red-tailed tropicbirds.

Etymology Mount Lidgbird is named by the naval officer Captain Henry Lidgbird Ball in honour of his father, George Lidgbird Ball. Ball junior first sighted Lord Howe Island in 1788 while he was on his way to Norfolk Island in the ship HMS Supply. He also named the nearby rock outcrop Ball's Pyramid.

Flora Cryptocarya forest, one of two types found on the island, the other being palm forest, is found in patches on the slopes of the mountain between elevations of 350 to 600 metres (1,150 to 1,970 ft) above sea level. Palm species growing on the mountain include Hedyscepe and Lepidorrhachis.

Climbing The North Ridge of Mount Lidgbird was climbed for the first time on 21 August 2011 by Greg Mortimer OAM and Dick Smith AC.

Worked examples

Example 1 — a first encounter with Mount Lidgbird

Start with the simplest possible case. Write down what Mount Lidgbird claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth 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 Mount Lidgbird 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 Mount Lidgbird 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 Mount Lidgbird

In research: Mount Lidgbird appears in earth 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 Mount Lidgbird 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: Mount Lidgbird is common in secondary-school and first-year university syllabi. It links to neighbouring topics Extinct volcanoes, Geography of Lord Howe Island, Hotspot volcanoes, so understanding it makes those chapters shorter.
In everyday life: Look for Mount Lidgbird 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.
