This is the first published geological map of the United States by the USGS. It is generally referred to as the McGee map after the compiler. The legend at lower left names and color codes eleven different geological groups. There is also very fine detail of hydrology. Vast areas of the western U.S. remain blank, reflecting the infancy and inadequacy of western geological explorations at the time, and coincidentally emphasizing the need for more congressional funding. The mapping of the King, Hayden, Powell and Wheeler surveys are evident in the West, but little else. This was the most up-to-date map at the time, but was soon superseded by Hitchcock's 1886 map that augmented the western states' geological detail.
