| Keywords: powellsurvey history blackandwhite tbt throwbackthursday utah coloradoriver glencanyon science portrait monochrome outdoor black and white Our #TBT photo shows John F. Steward, a member of the Powell Survey, in Glen Canyon, Colorado River. He is shown with the typical field equipment of those early Surveys: gun, pick, map case, and a canteen. This photo was taken in Kane County, Utah in 1872. Major John Wesley Powell led several expeditions along the Colorado River beginning in the summer of 1867 through 1879. As Professor of Geology and Natural History in the State Normal University of Illinois, he made the first trip in 1867 with the objective to increase the geological and zoological collections. Later expeditions were made under Congressional appropriations and Survey members included artists, geologists and topographers. Topographic base maps, compiled from the Powell Survey, were published as 1-degree sheets and covered 67,000 square miles. A truly fascinating read on the USGS mapping program from its inception in the various Surveys of the 19th century to the mid-1950's can be found in the History of the Topographic Branch (Division): pubs.usgs.gov/circ/1341/ Our #TBT photo shows John F.
