Landslides and Landforms now on the Washington Geologic Information Portal

Landslides and landforms data has been placed onto the Washington Geologic Information Portal. We’ve made a few changes to its appearance by dividing the data into separate layers, including 1:24,000- and 1:100,000-scale landslides from geologic mapping, miscellaneous landslides, landslides mapped using watershed analysis protocols, reconnaissance-level landslides, and Salish Sea landforms. We’ve also added the extents of landslide mapping for several layers, including the 1:24,000-scale landslides from geological maps and watershed analysis landslides.

While we’ve made a lot of improvements, this dataset will always be a work in progress. Landslides have not been mapped statewide using the same methods everywhere. This means that if the data doesn’t show a landslide in a given area, it doesn’t mean it’s not there—it is possible that it just hasn’t been mapped.

The data can be viewed on our Portal, or can be downloaded directly in GIS geodatabase format from our GIS data page.

Newly published: Faults and earthquakes in Washington State


We’re pleased to announce the release of a new publication!

Faults and Earthquakes in Washington State
by
J. L. Czajkowski and J. D. Bowman

fault_earthquake_map_20141216_as_18Summary:  Every year, relatively young faults are discovered in Washington through various methods, usually some combination of lidar, geophysics, seismicity, and (or) geologic mapping. This 45 x 36 in. color sheet shows Quaternary-age faults (those less than 2.58 million years old) and inactive faults and is compiled from several sources. Relocated earthquakes in and offshore of Washington State are also shown. A table in the plate provides links to many of the Washington State faults inventoried in the U. S. Geological Survey’s Quaternary-age Fault and Fold Database.

Three New 7.5-minute Geologic Maps Are Now Available

We are pleased to announce the release of three new geologic maps!

These publications are the result of our yearly 1:24,000-scale mapping efforts throughout the state and provide a detailed level of geologic mapping. Efforts are on-going to completely map the state at this scale. Digital versions of the maps can be found using the links provided below; paper copies may be purchased at myprint.wa.gov.

Click the image above to open the interactive 3D PDF. You will need a smidgen of patience, as this model will take a few moments to load.

Summary:  Well data, geologic mapping, cross sections, seismic lines, and other data  were incorporated into new digital and 3D models of the Puget Lowland that depict both bedrock elevation and unconsolidated sediment thickness. The 20-page report is accompanied by two oversized plates at 1:475,000-scale as well as an interactive 3D model in PDF format.

New Data on the Washington Geologic Information Portal!

After over a year of map development, and several years of data development, we’ve just added new data layers to several theme maps within the Washington Geologic Information Portal! The added or revised data can be found on either the Washington Interactive Geologic Map or the Geothermal Resources of Washington map themes. These new datasets are also downloadable in ArcGIS geodatabase format from our GIS data page.

Revisions and additions include:

  • 1:24,000-scale Geologic Mapping (Digital Data Series DS-10): compilation of  most published 7.5-minute geologic quadrangle mapping in Washington State.
  • Subsurface Database (Digital Data Series DS-11): compilation of location, lithology information, and supporting documentation for thousands of geotechnical boreholes and other subsurface exploration. The database was re-symbolized, we’ve improved the user interface, and the data is now available for public download.
  • Geochronology (Digital Data Series DS-6): new digital compilation of over 5,000 published and unpublished age estimates.
  • Rock Geochemistry (Digital Data Series DS-5): new digital compilation of over 3,500 published and unpublished major element and trace geochemical analyses. Note: We opted to not include data already compiled within the 2004 U.S. Geological Survey National Geochemistry Database.
  • Geothermal Favorability (Digital Data Series DS-9): new raster overlays showing modeled geothermal favorability, geothermal potential, and elevation restrictions. The download data also includes additional heat and permeability input rasters. For more information on how these models were generated, please see the newly published Geothermal favorability model of Washington State (OFR 2014-02).
  • Geothermal Direct Use (Digital Data Series DS-4): new digital data compilation of open- and closed-loop geothermal sites in Washington State, compiled from the Washington State Department of Ecology. Available data includes links to scanned well logs, permit applications, and other documents.
  •  Thermal and Mineral Springs (Digital Data Series DS-7): Large digital compilation of thermal and mineral spring locations, major element and isotope water chemistry, temperatures, and photos from both published literature and recent sampling by DGER. This dataset supersedes spring data previously available on our Portal and download data.
  • Geothermal Wells (Digital Data Series DS-8): update of gradient/heat flow wells, water wells with temperature, and geothermal permit locations. This dataset includes revised and (or) added gradients, updated or new temperature-depth logs, and recently drilled geothermal test wells.
