In the summer of 1923, the U.S. Geological Survey (USGS) organized an expedition to make a new map of the Grand Canyon, which included the last portion of the Colorado River. By 1923, only 27 known men traversed the length of Marble and Grand Canyons; only two were scientific. R.C. Moore was a member of the USGS expedition from 1914 until 1949 that endeavored to accurately survey a portion of the River that had not been adequately recorded (http://nationalmap.gov/grandcanyon/index.html). Moore was as an American geologist and paleontologist known for his work on Paleozoic crinoids, bryozoans, and corals. During the expedition he became professor at the University of Kansas. He served as president of the Geological Society of America in 1958 and, in 1970, the National Academy of Sciences awarded him the Mary Clark Thompson Medal (https://en.wikipedia.org/wiki/Raymond_Cecil_Moore). Condition: All are in very good condition.
