preferred location geologically because it was on the centerline of the <br />• proposed road. <br />The program at which we finally arrived included the following trenches. <br />A - centerline of road between Sta. 39+00 and Sta. 39+40 <br />1 - Sta. 57+80, left 115 feet <br />2 - Sta. 59+70, left 30 feet <br />3 - across and normal to centerline at Sta. 57+25 <br />6 - about parallel to centerline of road between Sta. 60+85 and Sta. <br />61+05, left about 20 feet (in the field this station was <br />reoriented from N-S to N30W) <br />7 - roughly parallel to the centerline of the road bet~deen Sta. 59+00 <br />and Sta. 59+40, right 35 to 40 feet. <br />Each trench was nominally to be 40 feet long and three to four feet wide. <br />• Trench Cutting <br />A D-5 Caterpiller bulldozer from the mine was used to prepare access to <br />trench locations that were not on an existing trail. A John Deere 690D-LC <br />backhoe with a 30-foot reach was contracted by PCC to dig the trenches. The <br />access was prepared and the trenches were all dug on May 6, 1992. All trenches <br />were dug between 1300 and 1450 when the operator was released. The backhoe <br />operator was instructed to cut benches that would facilitate access and <br />logging. He also, in most cases cut narrow ramps along the sides of the <br />trenches between benches, also facilitating access. <br />Logging Trenches <br />The procedure followed in logging the trenches was to measure by tape the <br />• length of each trench, determine the grade of landslope along the cut, measure <br />2 <br />
