~ . ~S3-~ <br />' ~ l~~• .3 3 -Kim loam, 3 to 5 percent slope <br />V~ <br />' This is a deep, well drained soil on gentle plains and alluvial fans at <br />elevations of 4900 to 5250 feet. It formed in mixed eolian deposits and <br />parent sediments from a wide variety of bedrock. <br />' Included in this unit are some soils that have sandy loam or loamy sand unde <br />lying material. <br />t <br />t Typically the surface layer is a brown to pale brown loam about 10 inches <br />' thick. The underlying material is a light clay loam or loam about 28 <br /> inches thick. Tlie substratum, to a depth of 60 inches is a loam or <br />' fine sandy loam. <br /> >. <br /> <br />1 ( ,'/ <br />' . Permeability is moderate. .4vailab•le water capacity is high.
