r exist. However, due to the presence of cobbles, boulders, and <br />' sandstone fragments, each attempt was met with refusal. As a <br />result, no undisturbed samples of site materials were obtained. <br />Results of the Standard Penetration Tests are shown on the <br />Drilling Logs to the right of the sampling points and presented <br />_ in Appendix B. As an example, a value of 10 indicates that 10 <br />hammer blows were required to achieve 12 inches of penetration of <br />the sampling spoon into the soil strata. In all cases, the <br />' Standard Penetration Test was peri`ormed using a hammer weighing <br />_ 140 pounds which was dropped from a height of 30 inches for each <br />blow. Samples were attempted at intervals of 5 feet or staggered <br />as deemed necessary by our field engineer to obtain samples of <br />various strata or to determines limits of the encountered <br />materials. <br />Locations of the test borings are shwon on Figure 2. Test <br />Borings No. 1 through No. 4 were placed along the slope crest, <br />two of which were placed in the bench area which had settled due <br />to past slope failures. Test Borings No. 5 and No. 6 were placed <br />on the slope at approximately one-third the slope height and Test <br />Borings No. 7 and No. 8 were located along the toe area of the <br />' proposed stabilized slope. <br />At the crest of the slope in the area of Test Borings No. 1 and <br />No. 2, coal waste was encountered to approximately 6 feet. Below <br />the coal waste and at Test Borings No. 3 and No. 4, very low <br />e <br />
