Mount Bona

Mount Bona 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 Bona rather than just read about it. In short: Mount Bona is one of the major mountains of the Saint Elias Mountains in eastern Alaska, and is the fifth-highest independent peak in the United States. It is either the tenth- or eleventh-highest peak in North America.

Key takeaways

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

Reference excerpt

Mount Bona is one of the major mountains of the Saint Elias Mountains in eastern Alaska, and is the fifth-highest independent peak in the United States. It is either the tenth- or eleventh-highest peak in North America. Mount Bona and its adjacent neighbor Mount Churchill are both large ice-covered stratovolcanoes. Bona has the distinction of being the highest volcano in the United States and the fourth-highest in North America, outranked only by the three highest Mexican volcanoes, Pico de Orizaba, Popocatépetl, and Iztaccíhuatl. Its summit is a small stratovolcano on top of a high platform of sedimentary rocks. The mountain's massif is covered almost entirely by icefields and glaciers, and it is the principal source of ice for the Klutlan Glacier, which flows east for over 40 miles (64 km) into the Yukon Territory of Canada. The mountain also contributes a large volume of ice to the north-flowing Russell Glacier system. Mount Bona was named by Prince Luigi Amedeo, Duke of the Abruzzi in 1897, who saw the peak while making the first ascent of Mount Saint Elias about 80 miles (130 km) to the southeast. He named it after the Bona, his racing yacht. The mountain was first climbed in 1930 by Allen Carpé, Terris Moore, and Andrew Taylor, from the Russell Glacier on the west of the peak. The current standard route is the East Ridge; a climb of nearby Mount Churchill is a relatively easy addition via this route as well.

Elevation Mount Bona's exact elevation is uncertain. USGS 1:250,000 topographical maps show an elevation of 16,421 feet (5,005 m), which was determined in 1913 by International Boundary Commission surveyors. However, USGS 1:63,360 topographical maps do not show a spot height, and their contour lines indicate a summit elevation of 16,550±50 feet (5045±15 meters). Many sources quote the latter figure.

Worked examples

Example 1 — a first encounter with Mount Bona

Start with the simplest possible case. Write down what Mount Bona 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 Bona 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 Bona 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 Bona

In research: Mount Bona 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 Bona 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 Bona is common in secondary-school and first-year university syllabi. It links to neighbouring topics Five-thousanders of North America, Landforms of Copper River Census Area, Alaska, Mountains of Unorganized Borough, Alaska, so understanding it makes those chapters shorter.
In everyday life: Look for Mount Bona 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.
