Samuel Franklin Emmons (March 29, 1841 – March 28, 1911) was an American geologist. He was born in Boston, Massachusetts. He graduated from Harvard University in 1861 and studied at the ''Ecole des Mines'' in Paris, France, from 1862 to 1864 and at the Frieberg (Saxony) mining school in 1865. In May 1867, he was appointed assistant geologist under Clarence King on the American geological exploration of the fortieth parallel, and in July 1879 became geologist in charge of the Colorado division of the United States Geological Survey. He traveled extensively throughout the United States in connection with his work, and in 1870 made a survey, along with A. D. Wilson, of Mount Rainier, the highest and most inaccessible peak in the Cascade Range. The largest glacier in the contiguous United States, Emmons Glacier, is located along their survey route and is named after Emmons. During the autumn of 1872, with Clarence King, Emmons discovered the locality of the supposed diamond fields in Colorado, and was active in exposing their fraudulent character. 〔famousamericans.net/samuelfranklinemmons/ accessed January 15, 2009〕〔books.nap.edu/html/biomems/semmons.pdf National Academy of Sciences Biographical Memoir, accessed January 15, 2009〕 Emmons is the namesake of Mount Emmons, Colorado, and Mount Emmons, Utah. ==Publications== * "(Descriptive Geology )," with Arnold Hague.
