    Warm Springs Soil Survey

    United States In cooperation with Department of Confederated Tribes of the Agriculture Warm Springs Reservation; Soil Survey United States Department Natural Resources of the Interior, Bureau of Conservation Indian Affairs; and Oregon of Warm Service Agricultural Experiment Station Springs Indian Reservation, Oregon 3 How to Use This Soil Survey General Soil Map The general soil map, which is the color map preceding the detailed soil maps, shows the survey area divided into groups of associated soils called general soil map units. This map is useful in planning the use and management of large areas. To find information about your area of interest, locate that area on the map, identify the name of the map unit in the area on the color-coded map legend, then refer to the section General Soil Map Units for a general description of the soils in your area. Detailed Soil Maps The detailed soil maps follow the general soil map. These maps can be useful in planning the use and management of small areas. To find information about your area of interest, locate that area on the Index to Map Sheets, which precedes the soil maps. Note the number of the map sheet and turn to that sheet. Locate your area of interest on the map sheet. Note the map units symbols that are in that area. Turn to the Contents, which lists the map units by symbol and name and shows the page where each map unit is described. The Contents shows which table has data on a specific land use for each detailed soil map unit.
