ScottP Posted January 6, 2009 Posted January 6, 2009 Clarence King! "American geologist and mining engineer who directed the survey of the 40th parallel (1867-78), an intensive study of the mineral resources along the site of the proposed Union Pacific Railroad, recorded in his classic volume, Systematic Geology (1878). This investigative effort included the first discovery of glaciers in the U.S. while studying the extinct volcanoes of Mounts Shasta, Rainier, and Hood. He is credited with introducing the use of contour lines on maps to indicate topographic features. Instrumental in forming the U.S. Geological Survey, he was then appointed its first head (1879-81). He wrote a series of Atlantic Monthly articles on Mountaineering in the Sierra Nevada (1872), marking a transition to popularized climbing sport." Quote
