The Table (British Columbia)

The Table (British Columbia) 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 The Table (British Columbia) rather than just read about it. In short: The Table, sometimes called Table Mountain, is a 2,021-metre (6,631 ft) high flow-dominated andesite tuya located 4 kilometres (2 mi) south of Garibaldi Lake, 15 kilometres (9 mi) northeast of Cheekye and 5 kilometres (3 mi) north of Mount Garibaldi, British Columbia, Canada. It rises over 530 metres (1,740 ft) above the surface of Garibaldi Lake, which lies less than 1 kilometre (1 mi) to the north.

Key takeaways

The Table (British Columbia) 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 The Table (British Columbia) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of The Table (British Columbia) from memory before moving on to harder problems.

Reference excerpt

The Table, sometimes called Table Mountain, is a 2,021-metre (6,631 ft) high flow-dominated andesite tuya located 4 kilometres (2 mi) south of Garibaldi Lake, 15 kilometres (9 mi) northeast of Cheekye and 5 kilometres (3 mi) north of Mount Garibaldi, British Columbia, Canada. It rises over 530 metres (1,740 ft) above the surface of Garibaldi Lake, which lies less than 1 kilometre (1 mi) to the north. The Table is almost impossible to climb because sections of the volcano have collapsed, creating steep and exceptionally rotten rock walls on all sides.

Geology The Table is part of the Garibaldi Lake volcanic field, a volcanic field that includes a group of nine small andesitic stratovolcanoes and basaltic andesite vents formed during the early Holocene. This in turn is part of the Garibaldi Volcanic Belt and of the Cascade Volcanic Arc that run from southwestern British Columbia to northern California caused by subduction of the Juan de Fuca Plate and Explorer Plate under the North American Plate at the Cascadia subduction zone. Canadian geologist Bill Mathews proposed in 1951 that The Table formed when magma intruded into and melted a vertical tube in the overlying Cordilleran Ice Sheet. The partially molten mass of hornblende-phyric andesite cooled as a large block, with gravity flattening its upper surface. Horizontal columns occur at numerous locations along the periphery of the mass. The absence of glacial erosion of the tuya suggests that it erupted during the early Holocene, just prior to the disappearance of the ice sheet. Similar formations can be found in the Wells Gray-Clearwater volcanic field, the Northern Cordilleran Volcanic Province and elsewhere in the Garibaldi Volcanic Belt.

In Film The Table is featured in Agent Cody Banks and in Stargate: The Ark of Truth in which it is the site of the village where the Ark was hidden. The title sequence of the film features The Table, with a graphics overlay of the village superimposed on it, as well as an aerial tour of the Mount Garibaldi and Tantalus Range area.

Worked examples

Example 1 — a first encounter with The Table (British Columbia)

Start with the simplest possible case. Write down what The Table (British Columbia) 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 The Table (British Columbia) 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 The Table (British Columbia) 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 The Table (British Columbia)

In research: The Table (British Columbia) 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 The Table (British Columbia) 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: The Table (British Columbia) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Garibaldi Lake volcanic field, Garibaldi Ranges, Holocene volcanoes, so understanding it makes those chapters shorter.
In everyday life: Look for The Table (British Columbia) 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.
