How to Use This Soil Survey Detailed Soil Maps The detailed soil maps can be useful in planning the use and management of small areas. To find information about your area of interest, you can locate the Section, Township, and Range by zooming in on the Index to Map Sheets, or you can go to the Web Soil Survey at (http://websoilsurvey.nrcs.usda.gov/app/). Note the map unit symbols that are in that area. The Contents lists the map units by symbol and name and shows the page where each map unit is described. See the Contents for sections of this publication that may address your specific needs. ii 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 1994. Soil names and descriptions were approved in 1996. Unless otherwise indicated, statements in this publication refer to conditions in the survey area in 1996. This survey was made cooperatively by the Natural Resources Conservation Service and the Montana Agricultural Experiment Station. It is part of the technical assistance furnished to the Granite County Conservation District. The most current official data are available through the NRCS Soil Data Mart website at http://soildatamart.nrcs.usda.gov. 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.
