Soil Surveys

This Web site provides links to complete, archived soil surveys for states in MLRA Soil Survey Region 7.

As time passes, the data in published surveys become dated. The official information about the soils in a given area is available from the Soil Data Mart, which provides the most current data about the soils. If spatial data are available, the Web Soil Survey also provides access to the most current information. It is an interface that allows the user to define an area of interest, to view and print a soil map, to assess soil data about the area, and to obtain information about the suitability of the soils for selected uses.

The Natural Resources Conservation Service is committed to making its information accessible to all of its customers and employees. If you are experiencing accessibility issues and need assistance, please contact our Helpdesk at 1 (800) 457-3642 or e-mail at For assistance with publications that include maps, graphs, or similar forms of information, you may also wish to contact the State or local office.
