A new geologic map of Seattle, Washington is nearing completion. This report, prepared for the 2005 Washington Hydrogeology Symposium, describes the status of mapping. The new map is the result of field mapping and compilation of subsurface geologic data during the years 1999-2004 and was funded by the City of Seattle and the U.S. Geological Survey. Data from more than 36,000 exploration points, geotechnical borings, monitoring wells, excavations, and outcrops were used in making the map. |
Download the geologic map as a 36"x60" PDF document (of2005-1252.pdf; 42.6 MB)
