pit (Photo 6). This may be attributed to the shallower depth of soil and rock ' overburden removed. Iron oxide staining is common on many of the joint surfaces. ' 5) Multiple narrow shear zones were observed along the temporary north and south walls of the middle level of the quarry (Photo 7). The shear zones varied in width from several inches to several feet across. The typical strike of 015°, and a nearly vertical dip was conducive for viewing multiple t exposures due to the orthogonal intersection of the shear zone with the wall orientations. 6) As noted in previous annual reports, a minor east-west striking unnamed fault zone is mapped in the final pit wall in the northwest corner of the main pit, and is also visible along the east wall of the main pit (Figure 3). The ' rock within the fault zone is more broken and blocky, with parallel fracturing and iron staining of joint surfaces common. Field measurements indicate ' that the fault has an apparent dip of 80°-85° to the south and a general strike azimuth of 260° to 270°. The width of the fault zone varies in the ' main pit between approximately 20 and 50 feet. As mining progresses, the north benches will continue to intercept the fault, which will increase the i footage that the fault is exposed along the final walls. The fault will continue to be intercepted near the northwest comer of the pit as the pit is ' excavated to the final depth. Based on the average dip of the fault, at approximately an elevation of 6,260 feet, the fault may be exposed across ' the floor of the main pit. It is unclear as to what impact the blockier rock will have on slope stability. t 7) Raveling conditions resulting from rock fragmentation during blasting and subsequent freeze/thaw conditions exist along each wall in the quarry, but appear more prevalent along the south wall. f 9
