To find information about your area of interest, locate that area on the Index to Map Sheets. Note the number of the map sheet and turn to that sheet. Locate your area of interest on the map sheet. Note the map unit 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. Also see the Contents for sections of this publication that may address your specific needs. 2 This soil survey is a publication of the National Cooperative Soil Survey, a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (formerly the Soil Conservation Service) has leadership for the Federal part of the National Cooperative Soil Survey. Major fieldwork for this soil survey was completed in April 2008. Soil names and descriptions were approved in June 2008. Unless otherwise indicated, statements in this publication refer to conditions in the survey area in 2008. This survey was made cooperatively by the Natural Resources Conservation Service; the Navajo Nation; the Navajo Mountain Soil and Water Conservation Service; and the Arizona Agricultural Experiment Station. The survey is part of the technical assistance furnished to the Navajo Mountain Soil and Water Conservation District and the Navajo Nation. Soil maps in this survey may be copied without permission. Enlargement of these maps, however, could cause misunderstanding of the detail of mapping. If enlarged, maps do not show the small areas of contrasting soils that could have been shown at a larger scale.

The buttes and mesa are in map unit 56, Torriorthents-Rock outcrop complex, 25 to 65 percent slopes. The foreground is in map unit 53, Sheppard-Sheppard, gypsic substratum complex, 2 to 11 percent slopes.
