Development of practical mapping techniques to show the three-dimensional distribution of geologic materials directly and to specified depths has significantly improved the ease and accuracy of preparing interpretive maps. The continued development and use of hydrogeologic maps based on the terrain map can be of direct value. Their use will also improve many interpretive maps showing waste disposal and construction conditions and rating geologic conditions for other land uses. In most geologic and hydrogeologic settings, geologic maps based on the stack-unit and terrain concept can provide the regional hydrogeologic predictability necessary for evaluating aquifer conditions and paths of potential contaminant transport, and the general information necessary for regional planning of the development and management of water and other resources. The development of three-dimensional stack-unit and terrain maps in Illinois has focused specifically on the glaciated portions of the state; bedrock has been included in the mapping in thin drift areas. Because the same mapping concepts apply, there is reason to believe stack-unit maps and terrain maps can be constructed for most geologic settings. (TRRL)
