"Representing the U.S. Army Corps of Engineers, Wheeler surveyed some 361,000 square miles of the southwest between 1869 and 1979…Wheeler's primary objective was to prepare a detailed topographic map of the West. In pursuit of this goal he divided the area of the West into ninety-five 'principal' rectangles, each rectangle comprising 2 degrees 45' minutes of longitude and 1 degree 40' minutes of latitude, to be covered in four atlas sheets."
