The Geological Survey is making a geologic map of the United States, which necessitates the preparation of a topographic bas map. The two are being issue together in the form of an atlas, the parts of which are called folios. Each folio consists of a topographic base map and geologic maps of a small area of country, together with explanatory and descriptive texts.
