The 1957 conference between Geological Survey and Mississippi River Commission officials designated the Geological Survey as the responsible agency for Mississippi Valley mapping. The Mississippi River Commission's annual mapping requirements are assumed by the Geological Survey as part of its regular mapping program. Series conversion materials supplied to the Mississippi River Commission to enable them to produce 15-minute maps at a 1:62,500 scale. Control requirements for mapping and methods for establishing control are presented. The exchange of data and information between the two agencies expedites the systematic mapping of the Mississippi Valley. Recent developments in instruments and procedures have increased both map production and quality.
