Bleuer, N. K., Woodfield, M. C. 1993, Plate 2. Map showing geologic/hydrogeologic terrain, Porter County, Indiana and adjacent areas: Indiana Geological Survey Open-File Study 93-02a.2
Notes: Publications in the Indiana Geological Survey Open-File series have been inconsistently named using a variety of series titles including "Open-File Report," "Open-File Map," and "Open-File Study." Prior to 1994, a publication in this series was generally referred to as an "Open-File Report" (but not always). To help reduce confusion created by these inconsistencies, the IGS now refers to every publication in the Open-File series as an "Open-File Study." To be entirely correct in writing a bibliographic reference for a publication, one should use the series name and number that appears on the publication itself.
Full county maps. Available in scales 1 in = 1 mi and ½ in = 1 mi. Each large-scale color, $15.00. Each small-scale color, $10.00.
