Geologic materials <br />directly influence rate and type of soil development. Soil <br />characteristics such as texture and mineral content are <br />directly related to geologic parent material. <br />Alluvial soils are represented b,y the Lamphier series <br />which are formed in moderately steep drainageways and concave <br />positions of mountain slopes. <br />Shallow to moderately deep soils over hard bedrock <br />include the Jerry and Unnamed Lithic Camborthid series. <br />`Phese soils are formed in residuum and from sandstone bedrock. <br />Ridges and drainageways are gravelly, cobbly or stony. <br />Coarse fragments make up a considerable portion of the <br />soils found in the area and are expressed as stone lines <br />in the alluvial soils and as the dominant material in many <br />of the C horizons. Many of the soils are quite cobbly, <br />gravelly and/or stony as a result. <br />1.4 METHODS <br />A field investigation was implemented during June, <br />1981• Soil series phase, series variants or complexes were <br />used as basic mapping units in the areas which are to be <br />disturbed by mining.
