Magnificent, huge atlas showing the area of the 40th Parallel Survey in topographical and geological maps. Wheat notes: "These are pioneer survey maps, and as such are most interesting. Mapping the West in so broad a cross-section had never before been attempted, a portent of things to come." King, at the age of 25, was made Geologist-in-charge of the Survey in 1867. He was formally ordered "to examine and describe the geological structure, geographical condition and natural resources of a belt of country extending from the 120th meridian eastward to the 105th meridian, along the 40th parallel of latitude with sufficient expansion north and south to include the lines of 'Central' and 'Union Pacific' railroads..." (Wheat). The topographical sheets depict features by brush shading rather than hachuring. In original binding -rare. Bound in green half leather with a label on the front, "Geological and Topographical Atlas Accompanying the Report of the Geological Exploration of the Fortieth Parallel. Clarence King, Geologist in Charge."
