N. R. Hasenmueller and R.L. Powell, 2006, Karst, Indiana Geological Survey Poster 4, 24" x 32" color poster.
About 10 percent of the Earth’s surface qualifies as karst landscape and as much as a quarter of the world’s population depends upon ground water from karst areas. This new Indiana Geological Survey poster includes pictures, diagrams, and discussions addressing the characteristics of the karst landscape, the development of karst, and potential sources of contaminants of karst terrains in southern Indiana. A map of Indiana showing the locations of karst areas in the state and a discussion of the ways one can help protect the karst environment are included on the poster.
Todd A. Thompson and Kimberly H. Sowder, 2006, Generalized Stratigraphic Column of Indiana Bedrock, Indiana Geological Survey Poster 6
This chart is a color 6-foot-tall illustration of general lithologies associated with Indiana rock units. Lithologies are simplified to show major lithologic variations through time, and rock units are displayed with thumbnails of the Indiana bedrock geologic map that show where the rocks occur within the State.
S.E. Brown and T.A. Thompson, 2005, Geologic Map of Glacial and Post-Glacial Deposits, Northern Lake County, Indiana, Indiana Geological Survey Miscellaneous Map 71, scale, 1:40,000.
Miscellaneous Map 71 provides geologic information about the glacial and post-glacial deposits of northern Lake County, Indiana. The geological heritage of this region has had a dramatic impact on the way people live, spanning generations of native Americans to the development of the mega-industrial complex along the shoreline of Lake Michigan. The map unit descriptions and cross sections include information about the subsurface geologic conditions, based on extensive subsurface exploration projects carried out by authors Brown and Thompson.
J.R. Hill; with historical contributions by W.S. Blatchley, revised 2005, Gold and Diamonds In Indiana–An Update, Indiana Geological Survey Circular 12, 55 p., 6 fig., 1 plate.
Since its first reprinting in 1963, Willis S. Blatchley's "Gold and Diamonds in Indiana" has been a best seller of the Indiana Geological Survey. Much of the appeal of Blatchley's report derives from the novelty of its topic. Most people do not think of the Midwest as an area in which either gold or diamonds are found. Like Mr. Blatchley's original, this report is intended not as a treatise on gold mining in Indiana but as a guide for the amateur gold panner who enjoys nature and the challenge of finding a few grains of gold along one of southern Indiana's scenic-upland streams.
Preparing for Indiana's Earthquake Risk, 2005, Indiana Geological Survey Miscellaneous Publication, video presentation on DVD.
In this 21-minute DVD program, you will learn about the earthquake risk in Indiana from Indiana Geological Survey geologists and from seismologists in Indiana and Ohio. You will also meet the State Emergency Management Agency staff, first responders, and experts in disaster preparedness who are working to make sure that the effects of a damaged infrastructure are minimized and that essential services continue with minimal interruption. State and local officials will describe what they are doing to mitigate potential and local officials will describe what they are doing to mitigate potential damage and loss of life, and share some very simple and inexpensive steps that every family should take to minimize the risk in their own homes.
