NATIONAL PARK SERVICE GEOLOGIC RESOURCES INVENTORY MAP PRODUCTION: CONVERTING 3 BILLION YEARS AND 85 MILLION ACRES OF GEOLOGY INTO GEOSPATIAL DATA
The U.S. National Park Service (NPS) manages 423 individual units covering more than 85 million acres. These lands contain a world-class cross section of geologic diversity that records more than half the geologic history of earth, ranging from the almost 3 billion year old Canadian Shield rocks in Voyageurs National Park to the nascent basalts of Kilauea Volcano in Hawai‘i Volcanoes National Park. In order to better understand the geologic processes at work in parks and provide sound geologic information for use in park decision making, the NPS Geologic Resources Inventory (GRI) program provides parks with a scoping meeting and a summary report, digital geologic-GIS maps covering the park extent and adjacent areas of interest, and a report that highlights park-specific geologic issues, features and processes. This poster showcases a sampling of select iconic examples of Archean to Holocene age geologic units located within parks using GRI map products.
