Subsurface Database Update


The Subsurface Database has been updated to include new geotechnical borings and quality water wells. This data is useful to anyone interested in subsurface geology. Lithology, layer thickness, USCS classification, links to documents, and other information can be obtained through the attribute tables. This dataset was also updated on the Subsurface Theme of the Washington Geologic Information Portal. Happy clicking!
