These maps delineate the entire Puget Sound shoreline by geomorphic type. The primary purpose of the mapping was to identify feeder bluffs, eroding shorelines that are important to maintaining nearby beaches. Knowledge of the distribution of these features can be used by local planners and resource agencies to better manage Puget Sound shorelines. The study emphasized mapping of coastal bluffs, but also extended to a wide range of other coastal landforms, including rocky shores, river deltas, and small lagoons and estuaries. This mapping project is described in the following report, available from the Department of Ecology: MacLennan., A. Johannessen, J.W., Williams, S.A., Gerstel, W., Waggoner, J.F., and Bailey, A., 2013, Feeder Bluff Mapping of Puget Sound, prepared by Coastal Geologic Services, Bellingham, for Washington Department of Ecology, Olympia WA, 117 pp and map folio.

Web Soil Survey (WSS) provides soil data and information produced by the National Cooperative Soil Survey. It is operated by the USDA Natural Resources Conservation Service (NRCS) and provides access to the largest natural resource information system in the world. NRCS has soil maps and data available online for more than 95 percent of the nation’s counties and anticipates having 100 percent in the near future. The site is updated and maintained online as the single authoritative source of soil survey information.

This is a polygon coverage of Physiographic Divisions in the conterminous United States cropped to the state boundary of Virginia. It was automated from Fenneman's 1:7,000,000-scale map, "Physical Divisions of the United States," which is based on eight major 1946 divisions, 25 provinces, and 86 sections representing distinctive areas having common topography, rock types and structure, and geologic and geomorphic history.
