The Pacific Northwest Soil Survey Regional Office, located in Portland, OR, provides soil data quality assurance, technical guidance, and field assistance to soil scientists as part of the National Cooperative Soil Survey (NCSS).  The SSR-1 area of responsibility is based on Major Land Resource Areas (MLRA). It includes the forests and croplands of western Oregon and Washington, the wheat and range lands of Washington, Oregon, and Idaho, and all of Alaska. SSR-1 is subdivided into management areas with local MLRA Soil Survey Offices that coordinate all soil survey activities within their area.

Other Soil Survey Formats
Hard-copy soil survey reports provide a snapshot of the soils information at the time of publication. This information becomes dated over time, and those seeking the most current data should access the official data from Web Soil Survey. For archival purposes, many hard-copy reports have been scanned and are available on CD-ROM. A complete list of the soil survey products and formats is available for Alaska, Idaho, Oregon, and Washington. A nationwide list is available from the List of Soil Surveys by State.
