"Waters of Indiana," the 2019 annual Indiana Geological and Water Survey calendar is now available for free (except the cost of shipping--($7.50). Across Indiana, water has left an indelible mark on the landscape. The calendar features a map of the state depicting our waterways that drain five primary watersheds, and numbered text describing various surface water features.The 21 by 33 inch calendar is printed in full color on heavy poster paper and is shipped rolled in a cardboard tube.

A story of oceans, uplift, and ice, Indiana's geological history is reflected in the vistas and landscapes you will see as you travel through the state. From the Indiana Dunes of Lake Michigan, one of the world's largest displays of lakeshore dunes, to the historic little town of New Harmony, where American geology had its beginnings, this book is your guide to 50 of the most significant and interesting sites in Indiana. You will find kettle lakes formed by melting glaciers, gorgeous waterfalls carved into the rock, and a world-renowned karst landscape peppered with sinkholes and caves. Explore the Falls of the Ohio, the location of the largest exposed Devonian fossil beds in the world, or wander through the campus of Indiana University and tour the buildings and carvings of Salem Limestone, a building stone treasured by architects. Researched and written by Polly Sturgeon, the Outreach Coordinator of the Indiana Geological and Water Survey, with help from her colleagues, this book is a cross section of the Hoosier state and a treasure of geological and historical surprises.
GEOLOGY_OF_LAWRENCE_COUNTY_INDIANA.GDB is an Esri geodatabase that contains feature classes and nonspatial tables that show and describe the bedrock and some unconsolidated geology of the twelve U.S. Geological Survey topographic 7.5-minute quadrangle that encompass Lawrence County, Indiana. These data were used by staff of the Indiana Geological Survey to produce Indiana Geological Survey Miscellaneous Map 90. The geodatabase contains the following elements; DataSources (nonspatial table), DescriptionOfMapUnits (nonspatial table), Glossary (nonspatial table), ContactsAndFaults (feature class), DataSourcePolys (feature class), GeologicLines (feature class), MapUnitPolys (feature class), and OtherPolys (feature class).
GEOLOGY_BARTHOLOMEW_COUNTY_INDIANA.GDB is an Esri File Geodatabase that contains eight feature data sets and three geodatabase tables detailing the geology of Bartholomew County, Indiana. The data shows the distribution of gently west-southwest-dipping (15 to 20 ft per mile) Mississippian, Devonian, and Silurian sedimentary rocks along the eastern margin of the Illinois Basin, and so the youngest rocks are found high in the hills along the western margin of the county and the oldest rocks in the deepest valleys near the eastern margin of the county. Bedrock is close to the surface in the hills along the western margin of the county, so contacts between the gently dipping bedrock units nearly parallel surface contours. A complex network of deep paleovalleys filled mostly with glacial outwash deposits trends north-south in the central part of the county beneath broad fluvial terraces and valleys. Wisconsin ice-contact glacial deposits cover bedrock throughout most of the eastern third of the county.
The Indiana Geological and Water Survey presents “Landmarks in Indiana Geology–A Timeline” to celebrate two important milestones—the bicentennials of Indiana University and the state of Indiana. Beginning in 1787, this timeline illustrates the unfolding of Indiana’s history of the science of geology; it features noteworthy events, scientists, places, publications, buildings, and industries that are part of Indiana’s geological legacy.
This story map is the digital version of the IGWS publication Special Report 74. Underground coal gasification (UCG) is a technology that can complement traditional methods of coal mining and surface gasification. This technology works by converting coal into a combustible gas (syngas) that can be used for industrial heating, power generation, and the manufacture of hydrogen, synthetic natural gas, or diesel fuel. In the UCG process, the cavity formed in the coal seam becomes the reactor, so the gasification of coal takes place underground instead of in a gasifier at the surface, as in the surface gasification process. Selecting appropriate sites for UCG plants and applying the best UCG technologies and practices are complex processes, and a variety of technical and geological factors must be taken into consideration to evaluate each potential site.
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.
The Indiana, Kentucky, and Illinois State Geological Surveys have been collecting physical and chemical data and mapping the New Albany Shale for many years. This story map is the most comprehensive digital compilation of geologic information about the New Albany Shale and its members. These data are important for regional evaluations and can be used by the public, industry, and state and federal governments.
This is the digital version of the long-produced publication of the Indiana Geological Survey, Directory 11. Industrial minerals produced in Indiana include common clay and shale, crushed limestone and dolostone*, dimension limestone, dimension sandstone, gypsum, peat, construction sand and gravel, and industrial sand. See Table 1 for Indiana industrial mineral production and value in 2015 (U.S. Geological Survey, 2016). In addition to these mined commodities, cement and lime are produced in Indiana. Although lime and some ground limestone are not produced from limestone mined at the site, listings for those companies are included as a service to those who use this directory. Also included are listings for three brick plants that contract out their mining to other companies and one producer of art clay. Approximately four million short tons of slag from steel production are produced in Indiana annually. Indiana ranks first nationally in production of slag. Industrial mineral companies operate in 81 of the 92 counties in the state. Some additional information on the Indiana industrial minerals industry is presented in Table 2 (number of operations, companies, national rank, and major uses of Indiana industrial minerals).
Indiana has experienced several glaciations in the past 2.6 million years. Immense sheets of ice, called glaciers, formed when snow accumulated over time, compressed into ice, and began to move under the pressure of their own weight. They flowed southward from Canada and dynamically changed the landscape through depositional and erosional processes. This story map focuses on the several different glaciation periods that sculpted Indiana's landscape.
