John Wesley Powell, a civil war veteran, botanist, geologist, and sociologist, was one of four men during the 1870s to lead a United States Geological Survey of the West. The J. W. Powell Survey unofficially began in 1867 when Powell led a small team of mountain men down the Colorado River and through the Grand Canyon for the first time in history. In 1870, Congress officially established a Geographical and Geological Survey of the Rocky Mountains region with Powell in charge. This momentous event was just the beginning of Powell’s life as a surveyor, and he continued leading surveys until 1894. Throughout this time, Powell and the botanists he employed were able to collect botanical specimens for numerous museums and herbariums across the United States. The most unlikely and least known botanist that traveled with J.W. Powell was his sister “Nellie” who had studied botany at Wheaton College. She wished to accompany her brother through Utah to make collections of flora during his 1871-72 expedition down the Green and Colorado Rivers. |Additional Sources: "Pyrrocoma.” Flora of North America, n.d. florataxon.aspx?flora_id=1&taxon_id=127795 Gray, Asa.
