Dutton having, on the advice of Greek scholars, changed the ‘c’ to an ‘s’. Dutton was a close associate of John Wesley Powell, G.K. Gilbert, and William Henry Holmes at the USGS. He was an energetic and effective field geologist: in 1875–1877 Dutton's field party mapped of the high plateaus of southern Utah, an area of rugged topography and poor access. Dutton had a distinctive flair for literary description, and is best remembered today for his colorful (and sometimes flamboyant) descriptions of the geology and scenery of the Grand Canyon region of Arizona. "Dutton first taught the world to look at that country and see it as it was... Dutton is almost as much the genius loci of the Grand Canyon as Muir is of Yosemite" – Wallace Stegner, Beyond the Hundredth Meridian. In 1891 he retired from the USGS to serve as commander of the arsenal of San Antonio, Texas; then as ordnance officer of the department of Texas. After retiring from the Army in 1901, he returned to the study of geology. Dutton spent his last years at the home of his son in Englewood, New Jersey.
