EXHIBIT I <br />LUSK PIT #36 <br />SOILS INFORMATION <br />Campo Series: Campo Series consists of deep, nearly level, moderately dark-colored <br />clay loams. These soils occur on uplands in all parts of Baca County. In a typical <br />profile, the surface layer (which is about 4" thick) is light brownish-gray clay loam that is <br />easily worked. The subsoil is brown clay, silty clay, and silty clay loam about 30" thick. <br />It is free of lime in the upper 14 inches. The lower part has lime spots and is calcareous. <br />Below a depth of about 40" is a very pale brown silty clay loam that is very strongly <br />calcareous. Campo soils are well-drained. They absorb water slowly and have a high <br />available water capacity. Because the slopes are nearly level and concave, these soils <br />receive a small amount of extra moisture from surface runoff from surrounding soils. <br />Potter Series: The Potter Series consists of shallow, gently sloping to undulating, light- <br />colored gravelly loams. They are underlain by caliche and occur in all parts of the <br />county. In a typical profile, the surface layer (which is about 8" thick) is grayish-brown, <br />gravelly loam. It is underlain by caliche. Potter soils absorb water well, but since they <br />are shallow, available water capacity is low. Runoff is medium. These soils are <br />susceptible to soil blowing and water erosion. <br />Wages Loam: Wages soil is deep and well-drained. It formed an alluvium on terraces. <br />Typically, the surface loam is 4" thick. The subsoil is clay loam 8" thick. The <br />underlying material is clay loam to a depth of 60" or more. Permeability is moderate. <br />Available water capacity is high. Effective rooting depth is 60" or more. Runoff is slow <br />to medium. The hazard of wind erosion is moderate to high. Slopes range from 0 to 3 <br />percent. This soil is subject to rare flooding. <br />Wiley Series: The Wiley Series consists of deep, nearly level to strongly sloping, light- <br />colored loams on less-mantled uplands in nearly all parts of the county. In a typical <br />profile, the surface layer is light brownish-gray loam about 5" thick. The upper part is <br />grayish-brown, slightly calcareous silty clay loam, and the lower half is pale brown, <br />strongly calcareous silt loam. The subsoil is hard when dry, but friable when moist. The <br />underlying material is pale brown silt loam that is friable, contains lime, and is easily <br />penetrated by plant roots. Wiley soils are naturally well-drained. These soils are <br />moderately permeable and have high available water capacity. They are high in natural <br />fertility, but are susceptible to both soil blowing and water erosion. <br />Wiley Loam, 3 to 5 percent slopes (WIC): This soil occurs mainly in the northern half <br />of the county. It has a profile similar to that described as typical for the series except that <br />the subsoil is light clay loam that is about 8" thick. The subsoil is slightly calcareous.
