Item Number: DI15

Since 1975, the Indiana Geological and Water Survey has collected coal stratigraphic data in accordance with the National Coal Resources Data System. This cooperative project with the U.S. Geological Survey generates, updates, and maintains coal resource information, including coal location, thickness, depth, stratigraphic position, and surrounding rock data. This interactive application allows users to interactively search, explore, and compare coal stratigraphic data. These data are important for regional coal resource evaluations and can be used by the public, industry, and state and federal governments.
