<br />' color is light brown to tan and is a clay loam. The boundary is <br />distinct. These soils should be salvaged to a depth of 15 to 18 <br />inches or until the color changes from dark to light. <br />' There are variants that can be identified from surface <br />appearance. In some places little pieces of gravel (1/8" to 1/2" <br />' in diameter) are quite uncommon while such gravels are common in <br />other places. The pattern of gravelly and non-gravelly soils <br />' seems to be related to erosion from the upland areas. As the <br />elevation increases, the gravel content also increases; however, <br />this is not an invariable rule. <br />' In the northwest corner of the affected land (north of the <br />current mining area) the slopes are much steeper and the <br />' influence of Green Mountain on the soils is readily apparent. The <br />' soil is a clay loam, but instead of gravels being present, the <br />stones are larger and can be up to 12 inches in diameter. <br />' However, the stones are not so common as to produce any problems <br />with salvage or with revegetation. Salvageable soil depths ih <br />' this area are somewhat less and range from 8 to 14 inches with a <br />' good average of about 9 to 10 inches. <br />Light Soils. The more coarsely textured soils (usually <br />' referred to as light soils) are restricted to upland areas along <br />ridges and the slopes of hills. The soils range from a light <br />' gray to tan color and from a silty clay loam to a stony or even <br />rocky sandy loam. Most commonly they are a silty clay loam with <br />some larger rocks present. These soils occupy about five acres <br />' total in the affected area. <br />The light soils are generally quite thick with an A-horizon <br />1 <br />31 <br />
