Welcome to the Washington State Geologic Information Portal! Through this online service offered by the Washington Division of Geology and Earth Resources, you can access interactive earth science mapping, data, and related information.
More types of geologic information will be added to the information portal in the future, so please visit regularly to see what's new. You may also subscribe to our mailing list to receive announcements of new additions to the portal, as well as notification of our publications releases.

Interactive Maps
Using our interactive maps, you can create, save, and print custom maps, find out more information about map features, and download map data for use in a geographic information system (GIS). In addition to a variety of geoscience layers that can be turned on and off, each interactive map has many base layers to choose from, so you can customize your map in any number of ways. Please note that because of the volume of data available through these interactive maps, data loading and identification operations may not be instantaneous; we thank you for your patience.

Other Earth Science Information Sites
High-quality geoscience mapping and data for Washington is available from other websites outside of DNR:
Interactive Maps
- USGS National Map Viewer - A U.S. Geological Survey site that allows you to interactively view "The National Map" data as a map, customize the view, and print a map
- USGS Earth Explorer - Allows you to search, download, and order U.S. Geological Survey products from many datasets
- Washington State Orthoimage Portal - Allows you to view and download orthoimagery of Washington, prepared from aerial photographs and other data
- Washington Department of Ecology GIS Applications - Access to GIS applications that the Department of Ecology uses in accomplishing its mission of protecting the land, air, and waters of the state. Topics include shoreline aerial photos, regulated facilities, coastal atlas, well log viewer, environmental data, and water quality information
- DNR Forest Practices Application Review System (FPARS) - FPARS is designed to streamline the processing of Forest Practices Applications and improves the public's ability to review proposed forest activities; it can also be used for creating base maps for other purposes
Downloadable Data
Other Earth Science Information Sources
- USGS National Geologic Map Database (NGMDB) - A U.S. Geological Survey resource for maps and related data about geology, hazards, earth resources, geophysics, geochemistry, geochronology, paleontology, and marine geology.
