Abstract
A stack-unit map shows the distribution of earth materials vertically from the surface to a specified depth and horizontally over a specified area. It also shows the succession of geologic units in their order of occurrence within the specified depth. This information is now available for the entire state of Illinois with the publication of the statewide stack-unit map of geologic materials to a depth of 15 meters (49.3ft). The statewide stack-unit map, which is made up of four separate, regional maps, provides basic geologic information for interpretive mapping for region, resource-based land-use planning and decision making. -Authors
