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.
