boundaries. Visual field observation and photographic analysis were used to delineate the <br />• boundaries for the very steep map units 101, 103, XBF, and 5103. <br />Mapping detail was at an Order 1/2 level for most of the study area. Order 1/2 map units <br />consisted primarily of consociations and complexes. Taxonomic units were soil series, soil <br />series variants, subgroups, great groups, and miscellaneous land types. Phases of soil series <br />were based on factors important to soil suitability and salvage, as well as inherent soil <br />properties. Map unit component percentages, and the percentages of major soil series <br />inclusions, were generated during the mapping phase. The slope categories used for the map <br />units reflect soil suitability and salvage depth as well es machinery limitations related to topsoil <br />salvage. All map unit boundaries were plotted in the field on the base map utilized for <br />mapping. <br />All map units were delineated as follows: <br />• If soils were dissimilar li.e., highly contrasting in physical or chemical properties or depth <br />of suitable soil), consociations of a minimum size of t.0 acre were delineated. <br />• If soils were similar (i.e., lowly contrasting in physical or chemical properties or depths of <br />suitable soil), consociations of a minimum size of 2.0 acres were delineated. <br />• Soil complexes were mapped when two or more kinds of soil or miscellaneous areas were <br />in a pattern so intricately mixed that the components could not be separately delineated <br />at the 1:4800 11" = 400'1 map scale li.e., the maximum size of map unit inclusions in <br />similar soils was 2.0 acres and the maximum size of mep unit inclusions in dissimilar soils <br />was 1.0 acres. <br />• Map unit descriptions include the site-specific percentage of the component series land <br />percentages for major inclusions) found in each map unit and reflect the site-specific <br />conditions (ranges, variability, associated competing soils) of the study area. <br />• All map units were correlated with existing SCS soil series, where possible. Series <br />variants were utilized where site-specific soil properties differed slightly from the <br />established soil series. <br />• Definitions and limits for the terms: phase, consociation, complex, variant, similar, and <br />dissimilar were applied as described in the revised Soil Survey Manual, Chapter 5-Map <br />Units (SCS 19801. <br />• <br />g Revised 9/98 <br />
