NPS Geodiversity Atlas—Indiana Dunes National Park, Indiana

Geodiversity refers to the full variety of natural geologic (rocks, minerals, sediments, fossils, landforms, and physical processes) and soil resources and processes that occur in the park. A product of the Geologic Resources Inventory, the NPS Geodiversity Atlas delivers information in support of education, Geoconservation, and integrated management of living (biotic) and non-living (abiotic) components of the ecosystem.

Introduction

[Site Under Development]
Indiana Dunes National Park has an incredible variety of geologic features and processes including glacial deposits, dunes, beaches, wetlands, and more!

Geologic Features and Processes

Features visible within the park, all within about 50 miles of Chicago and surrounded by myriad of industrial, urban, suburban, and rural settings, include the following:

  • Coastal/lacustrine features and processes

  • Eolian features and processes

  • Fluvial features and processes

  • Glacial features and processes

  • Paleontological resources

Geoconservation

Those varied geologic features and processes also create a multitude of resource management issues for park staff, including:

  • Shoreline erosion

  • Disturbed lands

  • Geologic hazards: slope movements, sand collapses, and earthquakes

National Park Service Geodiversity Atlas

The servicewide Geodiversity Atlas provides information on geoheritage and geodiversity resources and values within the National Park System. This information supports science-based geoconservation and interpretation in the NPS, as well as STEM education in schools, museums, and field camps. The NPS Geologic Resources Division and many parks work with National and International geoconservation communities to ensure that NPS abiotic resources are managed using the highest standards and best practices available.
