Willard Drake Johnson

Willard Drake Johnson 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 Willard Drake Johnson rather than just read about it. In short: Willard Drake Johnson (1860-1917) was an American glaciologist, topographer, cartographer, hydrographer, geologist, geographer, and ethnologist. His career began under the tutelage of Grove Karl Gilbert on the Lake Bonneville survey.

Key takeaways

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

Reference excerpt

Willard Drake Johnson (1860-1917) was an American glaciologist, topographer, cartographer, hydrographer, geologist, geographer, and ethnologist. His career began under the tutelage of Grove Karl Gilbert on the Lake Bonneville survey. In 1882 he joined US Geological Survey under John Wesley Powell. From 1882 until 1896 he was in the topographic portion of the survey. In 1888 he co-founded the National Geographic Society. From 1888 until 1890 he surveyed the Arkansas River in Colorado. In 1891 he became the chief of the California, where he co-founded the Sierra Club and became a good friend of John Muir. In 1895 Johnson went on an expedition to Sonora, where he studied the Seri Indians. In 1897 he joined the Water Resources Branch of the US Geological Survey, where he worked in Oklahoma. From 1904 until 1905 he worked in Utah and the Sierra Nevada, where he studied glacial geology. After that he worked for the US Forest Service in Portland, Oregon until 1916. He worked in the Grand Canyon until his death there on February 13, 1917. Mount Johnson in the Sierra Nevada of California is named in his honor.

Worked examples

Example 1 — a first encounter with Willard Drake Johnson

Start with the simplest possible case. Write down what Willard Drake Johnson 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 Willard Drake Johnson 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 Willard Drake Johnson 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 Willard Drake Johnson

In research: Willard Drake Johnson 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 Willard Drake Johnson 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: Willard Drake Johnson is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1860 births, 1917 deaths, 19th-century American geographers, so understanding it makes those chapters shorter.
In everyday life: Look for Willard Drake Johnson 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.
