The accompanying maps and related material describing the geology and coal deposits of the Dugger quadrangle were prepared as part of a cooperative program to appraise the coal resources of Indiana initiated by the Division of Geology, Indiana Department of Conservation, and the Geological Survey, United States Department of the Interior.
The field work on which the maps were based was done by the writer, assisted by E. D. McKay, between June 15 and August 31, 1949.
The Dugger quadrangle covers nearly 58 square miles in east-central Sullivan County, Indiana, between latitude 39° and 39°07'30" N. and longitude 87°15' and 87°22'30" W. Dugger, the largest town in the quadrangle and the main shipping point, is 30 miles south of Terre Haute. The mines in the quadrangle are served by the Illinois Central, the Chicago, Milwaukee, St. Paul & Pacific, and the Pennsylvania Railroads.
