The Indiana Geological Survey has been collecting physical and chemical data and mapping the Hymera Coal Member for many years. This publication is the most comprehensive digital compilation of geologic information about the Hymera Coal in Indiana that is currently available from the Indiana Geological Survey. The database is accompanied by an interactive application that is a visual presentation of the Hymera Coal Member. It allows users to interactively search, explore, and compare data on coal properties. These data are important for regional coal-quality evaluations and can be used by the public, industry, and state and federal governments.
