Geological data that are used for a broad range of academic and practical applications, including growth-management planning, dam safety, hazard and risk assessment, water resource appraisals, resource use and protection, education, recreation, and scientific research.

This dataset portrays the geology of Washington State at a scale of 1:100,000 (1 inch equals approximately 1.58 miles). The purpose is to make the geology of the state available as a seamless dataset for use in regional spatial analyses and other digital applications and for providing a framework for planning and land management and evaluating geologic hazards and resources. It was prepared in cooperation with the U. S. Geological Survey (USGS) National Geologic Mapping Program.

This service consists of 12 feature classes and 1 table containing 1:100,000-scale geologic mapping for Washington State. Feature classes include: attitude_points (structural data), contacts, dikes (dikes and sills), faults, folds (fold data), geologic dates (from sampled locations), geologic_unit_polygons (geologic unit polygon data), map_index (spatial location of all 1:100,000 scale data and their sources), map_line (linear geologic data), map_point (geologic point data), misc_polygons (miscellaneous polygon data), and volcanic_vents (vent data). Also included within the geodatabase is a related unit description table, unit_descriptions, which defines each unit as reported by the author of the published map, and provides age, lithology, and full unit descriptions.
