This report comprises digital spatial data that constitute a partial transcription of the 1:250,000-scale Geologic map of Washington - southwest quadrant (Walsh and others, 1987); digital base material, symbolsets, and ARC Macro Language (AML) procedures to create a geologic map on a shaded-relief base from the digital spatial data; and Postscript and RTL plotfiles for such a geologic map.
The digital transcription is incomplete: offshore folds and faults, the southern limit of the continental ice sheet in the Puget Lowland, the published base map (Washington Division of Geology and Earth Resources map TM-1), geologic unit correlation diagrams, and most of the explanatory material that accompanies Walsh and others (1987) are not present here.
