Bedrock Geology and Mineral Resources of Putnum County, Indiana
(Indiana Department of Natural Resources, Geological Survey, 1982) Mackey, John C.; Moore, Michael C.; Hill, John R.
Bedrock units from the Mansfield Formation (Pennsylvanian) to the Edwardsville Formation (Mississippian) crop out throughout Putnam County. Their present distribution is largely due to erosion and nondeposition. These rocks are on the northeast edge of the Illinois Basin and dip westward about 25 feet per mile. Local structural anomalies, such as small-scale monoclinal and synclinal features, punctuate the otherwise flat-lying strata in some places. The Mississippian-Pennsylvanian unconformity is evident in areas where the Mansfield Formation (Pennsylvanian) overlies rocks as old as the Edwardsville Formation (lower Middle Mississippian) and as young as the Elwren Formation (lower Upper Mississippian). The minerals industry of Putnam County is based almost entirely on limestone. Five quarries produce limestone raw materials for Class A through Class C aggregate, pulverized limestone, agricultural limestone, and cement. Sand and gravel from valley-train deposits of Wisconsinan age are the only other geologic commodities currently produced (1982). The once-healthy clay-shale industry is now dormant, though moderately extensive deposits of both raw materials remain throughout the county. Minor shows of fair-quality to poor-quality coal are exposed along the Pennsylvanian outcrop, but these deposits are not considered to be commercially valuable.
Environmental Geologic Maps for Land Use Evaluations in Johnson County, Indiana
(Indiana Geological & Water Survey, 1976) Hill, John R.
"INTRODUCTION: Johnson County has experienced considerable population growth from 1960 to 1975 because of internal expansion and its proximity to Marion County. In 1970 its population was 61,138, a 40-percent increase over the previous (1960) census of 43,704. The Johnson County area has undergone such growth because: (1) it has substantial supplies of ground water; (2) high-traffic-volume thoroughfares, such as State Highways 135 and 37, U.S. Highway 31, and Interstate 65, cross the county; and (3) its land is generally well suited to construction. Nearly all the county embraces landforms based on glacially derived sediments that were deposited by ice, wind, and water. Glacial till (an unconsolidated material composed of sediments ranging in size from clay to boulders) that was deposited in numerous stages during the Ice Age blankets nearly all the count except a few localities south of Nineveh along the Johnson-Brown county line. Sand and gravel, washed from the ice as it retreated from the area nearly 20,000 years ago, exist now as sinuous valley train deposits. Some of the old glacial drainageways are now occupied by such streams as Grassy, Brewers, Buckhart, and Sugar Creeks. The overall thickness of the glacial deposits ranges from 0 to nearly 300 feet and has largely been determined by the underlying bedrock topography and glacial depositional processes. The information presented in this report supplements information already available in other reports that are pertinent to land use planning in Johnson county. To avoid duplication of existing material, very little has been said here about geologic history, engineering properties of the glacial drift, geomorphology and soils geology. Rather, this report concentrates on subjects for which little information is currently available: (1) depths to water table, (2) sand and gravel resources potential, (3) drift thickness, and (4) geologic factors affecting land use suitability to sanitary landfilling."
Environmental Geologic Maps for Land Use Evaluations in Morgan County, Indiana
(Indiana Geological & Water Survey, 1976) Hartke, Edwin J.; Hill, John R.
"Morgan County, a part of Planning Region 8 and represented on the Hoosier Heartland Coordinating Commission, is in south-central Indiana about 25 miles southwest of Indianapolis, the core of a large and expanding urban-industrial complex. Much of the growth pressure imposed on the dominantly rural, agriculturally oriented county results from the ease of access afforded to Indianapolis by three major highways that radiate from the center of the capital city into the county. Other factors that contribute to growth pressure are the attractive wooded hills in the southern part of the county and geologic conditions that generally favor homesite development. Certain considerations must be made, however, to determine the type of development best suited for given areas and the limits that must be imposed on development. The development potential of an area is partly controlled by its geologic environment and available resources. The maps compiled for this report are designed to provide guidelines for the planner and the developer so that they may make the best use of the resources of the county while avoiding environmental hazards. To assist in achieving these ends, information based on geology, hydrology, and soils in presented here in special regard to mineral resource potential and sanitary landfill suitability, and availability of industrial minerals were compiled originally on a scale of 1 inch to 1 mile. They have been reduced in size for this report, but the large-scale maps may be consulted in the offices of the Morgan County Plan Commission and of the Indiana Geological Survey. The sanitary landfill and mineral resources maps are self explanatory. The map showing drift thickness can be used in several kinds of studies that lead to use-suitability maps."
Environmental Geology of Lake and Porter Counties, Indiana - An Aid to Planning
(Indiana Geological Survey, 1975) Hartke, Edwin J.; Hill, John R.; Reshkin, Mark
Lake and Porter Counties are subdivided into three physiographically and geologically distinct regions: (1) the Calumet Lacustrine Plain, (2) the ValparaisoMorainal Area, and (3) the Kankakee Outwash and Lacustrine Plain. The surficial deposits of these regions, which range in thickness from 40 feet near the Kankakee River to more than 250 feet near Valparaiso, Ind,. Are the products, either directly or indirectly, of the Wisconsinan Age of glaciation. The Calumet lake plain is characterized by low-lying complexly intermixed clay, sand, and silt deposits, mostly of glacial Lake Chicago origin , The Valparaiso Moraine forms high ground in the two counties and is composed of clay-rich to fine sandy till. Sand and fine gravel deposits constitute the bulk of the Kankakee Outwash and Lacustrine Plain, this area being the low-lying outwash and flood plain for the glacially derived rivers as well as for the present Kankakee River. The two-county area has an abundance of geologic and geologically related resources; some of the most important are: (1) groundwater of the Kankakee Outwash and Lacustrine Plain and Valparaiso Morainal Area, (2) sand deposits of glacial Lake Chicago and of recent origin, (3) rich soils developed on the Valparaiso Moraine and Kankakee outwash plain, and (4) surface water in the form of streams, rivers, and small lakes. Some of these resources have already been damaged during the course of man’s habitation and use, but all can, with proper understanding of the problems and the willingness to act, be saved from further unnecessary degradation. Certain kinds of land use, which are partly dependent on the local geology, are potential sources of difficulty. These include (1) siting and use of sanitary landfills, (2) placement of septic systems, sewage lagoons, and industrial holding ponds, (3) management of flood plains, (4) development of the Lake Michigan shoreline, (5) construction of all kinds in areas where little is known about the engineering and hydrologic properties of the materials, (6) disposal of industrial wastes by deep well injection methods, and (7) development of groundwater supplies without sufficient hydrologic and geologic data. The environmental problems of Lake and Porter Counties, are related to geology, are as varied and complex as the materials themselves. Specific questions related to a given problem are best answered by the competent consultant equipped to do so. This report, though intended to supply valuable geologic information on a variety of land use related subjects, should not replace onsite evaluation of the salient parameters involved with each problem that potentially arises whenever man uses earth materials or otherwise disturbs or rearranges the natural earth condition.

Geology as a Contribution to Land Use Planning in LaPorte County, Indiana
(Indiana Geological Survey, 1979) Hill, John R.; Carr, Donald D.; Hartke, Edwin J.; Rexroad, Carl B.
LaPorte County, in northwestern Indiana, is in a geologically complex region underlain at shallow depths by depositional sequences of glacial till, outwash sand and gravel, and lacustrine silt and clay. The combined agents of ice, wind, and water have sculptured these deposits into a topographically varied landscape ranging from sandy flats of the Kankakee Outwash and Lacustrine Plain to partly wooded hilly uplands on the Valparaiso Moraine. Beneath the glacial materials, which range from 25 to 350 feet in thickness, is a sequence of Paleozoic rocks that is about 4,000 feet thick. Limestone, dolomite, sandstone, and shale, complexly interlayered and varying in thickness, make up the bedrock units, which provide ground water potential and contain potentially commercial deposits of gypsum near LaPorte. Most of the environmental geologic factors are dependent on the thickness, continuity, and physical properties of the unconsolidated deposits that make up the surface of the county. The texture, mineralogy, and depositional origin of these sediments largely determine their engineering properties and subsequent suitability for sanitary landfilling, septic systems, and construction. The availability, quantity, and quality of ground water also depend on the geologic properties of the unconsolidated glacial deposits and on the underlying bedrock formations. Ground water, discussed in this report, is abundant throughout much of LaPorte County because of porous and permeable sand and gravel deposits. Besides the indirect applications of geology to environment, some earth materials have commercial value in their own right. Sand and gravel, clay, peat and marl, and gypsum and anhydrite are valuable commodities that may be extracted from glacial drift or bedrock.

The Indiana Dunes-Legacy of Sand
(Indiana Department of Natural Resources, Geological Survey, 1974) Hill, John R.
The area including the Indiana Dunes State Park and Dunes National Lakeshore is unique in its diversity of geologic features and terrain. The forces of glaciers, wind, and water have combined over the eons to create picturesque morainal topography, a vast freshwater lake, great expanses of sand in the form of beaches and dunes, and bogs containing exotic plant species. Soon to be completely surrounded by an ever-expanding urban-industrial complex, the dunes area will remain as a lasting monument to the complexity and beauty of nature.
