A wall-sized geological map of Kentucky, the product of 18 years of work, has just been released. Produced by the U.S. Geological Survey (USGS) in cooperation with the Kentucky Geological Survey (KGS) at the University of Kentucky, the map is unique, according to state geologist Donald Haney, because it is the first and only state map ever produced in detailed form from geologic quadrangle maps already available from the KGS.

At a scale of 1:250,000, the map shows the surface distribution of various types of rock throughout the state, as well as geologic structure, faults, and surface coal beds. Numerous geologic sections, stratigraphic diagrams, correlation charts, and structure sections accompany the map. Compiled by R. C. McDowell and S. L. Moore of the USGS and by G. J . Grabowski of the KGS, the map was made by photoreducing and generalizing the detailed geologic quadrangle maps.
