A. Map of the United States Exhibiting the Present Status of Knowledge Relating to the Areal Distribution of Geologic Groups. 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 formations. 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 This was the most up-to-date map at the time, but was soon superseded by Hitchcock's 1886 map that augmented the western states' geological detail. Condition: Clean and bright with isolated foxing near the left neatline, slight toning along the folds, and one short split at a fold intersection. (B+)

B. Map of the United States Exhibiting the Progress Made in the Geographic Survey. This map shows the progress of the United States geologic surveys. The primary focus is on the western states including Colorado, Utah, Nevada and California. The legend shows four different surveys: Triangulation, Area Surveyed by Geological Survey, Area Surveyed by Northern Transcontinental Survey, and Area Surveyed by other Organizations. Condition: There are two clean fold separations that extend 4.5" and 1.5" into map, light offsetting, and minor toning at top where the map folded into the report. (B)
