As coal companies closed business in Indiana many times they deposited their records at the Indiana Geological Survey (IGS). The records in most cases were delivered in boxes or full filing cabinets without documentation. The IGS has preliminarily sorted through the records filing them by company and if possible county or Township-Range to make them discoverable. The records can contain anything from maps, analysis, logs with or without picks, descriptions, correspondence, etc.
