Geologic maps are our most important and complete compilation of information about the solid Earth we live on, and we cannot understand the Earth without them. We use geologic maps and the fundamental information they provide in many ways. Geologic maps help delineate fragile habitat and ecosystems, protect against natural hazards, and find needed resources. The following information is developed from the AGI Environmental Awareness Series book, "Meeting Challenges with Geologic Maps" by William A. Thomas and others (for more AGI publications click here). This information includes some basics about geologic maps, how geologists make geologic maps (contributed by R.D. Hatcher, Jr.), an assessment of the value of geologic maps, and specific examples of how geologic maps have been used to meet challenges across the United States.

Examples of Geologic Maps Meeting Challenges
The following examples represent the wide range of geologic map uses.
The examples are widely distributed geographically, as geologic maps
have valuable uses in every part of our country, and throughout the
world. The maps are organized in four subject categories: Environment,
Hazard Mitigation, Resource Evaluation, and Land Use Planning. Click
on any map name below to view the example. You will need Adobe Acrobat
to view the examples. Click here
to get Adobe, if you do not have it already installed on your computer.
