not been determined by the time field work was undertaken. As a <br />result these areas were not specifically examined, although in • <br />traversing throughout the project all but Areas E and G were <br />observed. Geologic and related factors that could affect these <br />stockpile areas are underlying rock type and surficial material, <br />structure of the bedrock, and topography and drainage. The <br />evaluation of these factors and certain others establish the <br />feasibility of the proposed stockpile areas. <br />Acreage determinations were made by electronic planimeter for <br />each stockpile area. These determinations are rounded to the <br />nearest half acre. <br />4.4.1 Stockpile Area A. This area is in the north-central part of <br />sec. 8, just north of the sedimentation pond, and includes about <br />2.5 acres. • <br />Rock Type. The site is underlain primarily by shale bedrock, <br />although it is doubtful that site preparation will encounter <br />bedrock. <br />Structure. This location is midway between the axes of Fish <br />Creek anticline on the west and the unnamed syncline on the east. <br />Structure is not anticipated to have an adverse effect on the <br />stockpile. <br />Topography and Drainage. This area is on a topographic slope <br />above the left abutment of the embankment. <br />Comments and Evaluation. It is unlikely that bedrock will be <br />encountered in preparing the stockpile site. If trenches or <br />keyways are cut to maintain stability of the stockpile they should <br />be oriented northeast-southwest essentially parallel to the • <br />28 <br />
