fFNFRAL SOIL M4P <br />iIOLORFS RIVER BASIM <br />COLORADO AND UTAH <br />The general soil map of the Dolores River Basin shows, in color, the soil units <br />for broad land use planning. Each soil unit is a unique natural landscape that has <br />a distinct pattern of soils and of relief and drainage features. A unit typically <br />consists of one or more soils of major extent and some soils of minor extent. It <br />is named for the major soils. The kind of soil in one unit can occur in other <br />soil units, but in a different pattern. <br />The map provides a broad perspective of the soils and landscapes in the survey <br />area. It provides a basis for comparing the potential of large areas of general <br />kinds of land use. Areas that are generally suitable for certain kinds of farming <br />or other land uses can be identified on the map. Likewose, areas of soils having <br />properties that are distinctly unfavorable for certain land uses can be located. <br />Because of its small scale, the map does not show the kind of soil at a specific <br />site. Thus, it is not suitable for planning the management of a farm or field <br />or for selecting a site for a road or building or other structure; the kinds of <br />soils in any one soil unit ordinarily differ from place to place in slope, depth, <br />stoniness, drainage, or other characteristics that affect their management. <br />This general soil survey is useful in that soils with similar characteristics <br />and suitability can be located and related to different parts of the basin. The <br />broad characteristics and relationships can be used in a general way to interpret <br />the potential of soils for agricultural, recreational, commercial, and industrial <br />uses. Problems of erosion, sediment yield, present land use, and future development <br />are interrelated with soils and their distribution. <br />
