This guide provides information for planning a field trip to the Indiana Limestone District. This district, located in Monroe and Lawrence Counties, Indiana, is responsible for material that has dominated the building-limestone market in the United States for nearly a century. A few of the many well-known buildings using Indiana limestone are the Pentagon, Empire State Building, and Chicago Museum of Science and Industry. This guide is organized into five parts: part 1 contains detailed background information on the Indiana Limestone District; part 2 features miscellaneous information including an Indiana geological map, a graph of Indiana dimension limestone production, and a list of prominent buildings and monuments; part 3 contains the field trip guide, which features a detailed route through Monroe and Lawrence counties with numerous sites of interest identified and described; part 4 is a glossary of building stone and masonry terms; and part 5 contains a 33-item list of resource materials, including a bibliography, videocassettes, audio-tape cassettes, and maps. Two appendices include the dimension limestone production in Indiana and the United States; and a chronological history. (DB)
