Reference excerpt

John Wesley Powell (March 24, 1834 – September 23, 1902) was a U.S. Army soldier, explorer of the American West, and director of major scientific and cultural institutions. He is famous for his 1869 geographic expedition, a three-month river trip down the Green and Colorado rivers, including the first official U.S. government-sponsored passage through the Grand Canyon. Powell was appointed by US president James A. Garfield to serve as the second director of the U.S. Geological Survey (1881–1894) and proposed, for development of the arid West, policies that were prescient for his accurate evaluation of conditions. He also spent time among the Native Peoples of the Colorado Plateau and wrote an influential classification of North American Indian languages. Two years prior to his service as director of the U.S. Geological Survey, he had become the first director of the Bureau of Ethnology at the Smithsonian Institution where he supported linguistic and sociological research and publications. He was also the first president of the Anthropological Society of Washington, founded in 1879. Powell was a proponent of Lewis H. Morgan's stages of human progress, and regarded Native Americans as culturally savage or barbarian. He advocated for overthrow of indigenous societies and the gradual replacement of native hunting practices with sedentary agriculture, as well as the cultural assimilation of Native people into the United States. Powell was in favor of developing agriculture on water-rich public lands, leaving the rest for grazing animals. From 1894 to 1899, Powell held a post as lecturer on the History of Culture in the Political Science department at the Columbian University in Washington, D.C. He was elected a member of the American Antiquarian Society in 1898.

Early life Powell was born in Mount Morris, New York, in 1834, the son of Joseph and Mary Powell. His father, a poor itinerant preacher, had emigrated to the U.S. from Shrewsbury, England, in 1831. His family moved westward to Jackson, Ohio, then to Walworth County, Wisconsin, before settling in rural Boone County, Illinois. As a young man he undertook a series of adventures through the Mississippi River valley. In 1855, he spent four months walking across Wisconsin. During 1856, he rowed the Mississippi from St. Anthony, Minnesota, to the sea. In 1857, he rowed down the Ohio River from Pittsburgh to the Mississippi River, traveling north to reach St. Louis. In 1858, he rowed down the Illinois River, then up the Mississippi and the Des Moines River to central Iowa. In 1859, at age 25, he was elected to the Illinois Natural History Society.

Powell studied at Illinois College, Illinois Institute (which would later become Wheaton College), and Oberlin College, over a period of seven years while teaching, but was unable to attain his degree. While at Illinois College, he was a member of Sigma Pi Literary Society. During his studies Powell acquired a knowledge of Ancient Greek and Latin. Powell had a restless nature and a deep interest in the natural sciences. This desire to learn about natural sciences was against the wishes of his father, yet Powell was still determined to do so. In 1860, when Powell was on a lecture tour, he began to feel that a civil war was inevitable; after enlisting, he decided to study military science and engineering to prepare himself for the conflict.

Civil War and aftermath Powell's loyalties remained with the Union and the cause of abolishing slavery. On May 8, 1861, he enlisted at Hennepin, Illinois, as a private in the 20th Illinois Infantry. He was elected sergeant-major of the regiment, and when the 20th Illinois was mustered into the Federal service a month later, Powell was commissioned a second lieutenant. While stationed at Cape Girardeau, Missouri, he recruited an artillery company that became Battery 'F' of the 2nd Illinois Light Artillery, with Powell as captain. On November 28, 1861, Powell took a brief leave to marry Emma Dean. At the Battle of Shiloh, he lost most of his right arm when struck by a Minié ball while in the process of giving the order to fire. The raw nerve endings in his arm caused him pain for the rest of his life. Despite the loss of an arm, he returned to the Army and was present at the battles of Champion Hill, Big Black River Bridge, and in the siege of Vicksburg. Always the geologist, he took to studying rocks while in the trenches at Vicksburg. He was made a major and commanded an artillery brigade with the 17th Army Corps during the Atlanta campaign. After the fall of Atlanta he was transferred to George H. Thomas' army and participated in the battle of Nashville. At the end of the war he was made a brevet lieutenant colonel but preferred to use the title of "major". After leaving the Army, Powell took the post of professor of geology at Illinois Wesleyan University. He also lectured at Illinois State Normal University for most of his career. Powell helped expand the collections of the Museum of the Illinois State Natural History Society, where he served as curator. He declined a permanent appointment in favor of exploration of the American West.

Worked examples

Example 1 — a first encounter with John Wesley Powell

Start with the simplest possible case. Write down what John Wesley Powell 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 John Wesley Powell 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 John Wesley Powell 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 John Wesley Powell

In research: John Wesley Powell 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 John Wesley Powell 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: John Wesley Powell is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1834 births, 1902 deaths, Activists from New York (state), so understanding it makes those chapters shorter.
In everyday life: Look for John Wesley Powell 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.
