<br />-7- <br />deposits within the valley bottom and fine to coarse mlluvium in the <br />higher plateau area. Topsoil depth ranged from approximately 1/2 to • <br />2 feet within the valley bottom area to as deep as 5 feet in the <br />plateau area. Existing fill was also encountered in proximity to the <br />Bear Mine acd railroad spur areas between depths 1 to 8 feet. The <br />fill consisted of clay and gravel and coal waste. <br />The fine sands and silts encountered in the valley bottan are <br />generally loose to medium dense and extend to depths 3 to 14 feet. <br />The underlying coarse granular soils are relatively dense and range to <br />boulder size material. On the flatter plateau area, stiff to very <br />stiff and medium plastic clays with scattered to frequent bedrock <br />fragments are mast predominant. Gravel to boulder size rock fragment <br />material was encountered in the soil near the west end of the plateau <br />(borings X11 through D-15) and on the higher sloping azeas (borings <br />I-2 and I-3). , <br />Sandstone with interbedded shale was encountered at depths 27.5 <br />and 36 feet in the valley bottom area (borings J-1 and B-1) and at <br />19 feet near the water storage tank (boring I-2). Bedrock was not <br />encountered in the remaining pond areas to the depth explored, <br />25 feet. Clay soils were encountered along the upper road section in <br />borings A-6, A-7 and A-8. <br />Bangles obtained during the exploration program were subjected to <br />various laboratory tests to determine their standard properties, shear <br />strength characteristics, permeabilities and settlement/swell poten- <br />tial. Results of laboratory testing are presented on Figs. 11 <br />through 44 and summarized on Tables I through IV. <br />• <br />
