1 <br />' that ranges from 4 to 8 inches in depth. On steep slopes where <br />' $llllfi and C'ercocaro~ stands occur, the soil is very rocky <br />and undeveloped, but these areas are small and uncommon. Soil <br />' salvage depths average 6 to 7 inches except in the shrub areas <br />where salvageable soil is essentially absent. <br />' $lightLy Eroded Soils. Although erosion of these soils <br />' is not a prominent characteristic, the presence of some drainages <br />and deep arroyos indicates some erosion has occurred in the past <br />' due to mismanagement. Usually these soils are a mixture of the <br />deep, heavy clay loams that surround the drainage areas and the <br />' light, well-drained soils of upland sites. <br />Because most of the soil for reclamation will come from the <br />clay loams of the lowland areas, these mixed soils are of little <br />' importance other than as an indicator of what the reclamation <br />potential of a mixed soil would be. In general, the mixed soils <br />' are somewhat drier than the clay loams but are much better than <br />upland soils. They revegetate naturally quite rapidly where <br />' moisture and stability are adequate. <br />' Disturbed Soils. Disturbed soils fall into three <br />categories: (1) areas mined for clay, (2) areas mined for gravel, <br />' and (3) recreational motorcycle facility. <br />In areas mined for clay before the law, little attention was <br />' paid to topsoil salvage. The soil and overburden were simply <br />t stripped simultaneously and placed in long windrows. As a <br />result, various types of materials can be found throughout these <br />' areas. They range from areas that have a soil-like material as <br />well as less capable materials down to a sandy material that <br />' 32 <br />
