Read moreOilfields, coal basins and even the surface of Mars are mapped by the United States Geological Survey, the federal agency founded in 1879. The main body here is early twentieth-century coal, oil and geological sheets covering Pennsylvania's Gaines oil region, Oregon's Coos Bay coalfield, Appalachian structures and western coal-bearing formations, relating local extraction districts to wider geological systems. Other maps examine cement materials, industrial markets and the distribution of resources across states, and a later Mars photomosaic associated with NASA and the Survey carries the collection into planetary mapping.
