1100318 R0T0 0811 JRW1 18 <br />An additional major episode of slope landslide movement occurred on September 6, 2009. This <br />movement is nested within the Pikeview Landslide boundaries identified in Photograph 10 and <br />overlaps the south flank of the rubblized debris on the slope generated from the Pikeview <br />Landslide. The September 6, 2009 episode of landslide movement is consistent with a <br />translational rock slide on the same failure surface on which the Pikeview Landslide occurred. <br />Photograph 16 shows a panoramic ground photograph of the Pikeview Landslide after the <br />September 6, 2009 episode of movement. <br />By December 9, 2010, another episode of Pikeview Landslide movement had fully matured. By <br />this time, the portion of the slope within the northern portion of the Pikeview Landslide had <br />translated downslope forming a conspicuous graben behind (west of) the translated block. <br />Photograph 17 shows the condition of this area on December 9, 2010. <br />The Pikeview Landslide damaged the engineered improvements of the Pikeview Quarry in four <br />principal manners. First, the Pikeview Landslide made the west highwall of the Pikeview <br />Quarry and portions of Area H unsafe, rendering further mining operations impossible. Second, <br />the Pikeview Landslide damaged the west highwall slope by obliterating the engineered bench <br />structure on the slope. The slope movement caused the underlying bedrock to rubblize thereby <br />erasing the structures of the benches. Third, the Pikeview Landslide damaged the slope by <br />destabilizing the slope, creating large cliff faces, and rubblizing the slope making it impossible <br />to reclaim the Pikeview Quarry without a substantial reclamation plan. In other words, the <br />Pikeview Landslide made the approved Reclamation Plan impossible to implement without <br />significant modifications as are discussed in Section 8. Fourth, the Pikeview Landslide <br />damaged previously reclaimed sections of the Pikeview Quarry by significantly disturbing and <br />destabilizing these areas. <br />The damage to the engineered improvements of the Pikeview Quarry from the Pikeview <br />Landslide resulted in the immediate impracticality of further aggregate extraction. The damage <br />made the west wall of the Pikeview Quarry unstable thereby eliminating safe operations for <br />aggregate extraction. Furthermore, the Pikeview Landslide immediately rendered the current <br />Mining Plan and Reclamation Plan obsolete. The landslide dramatically altered the <br />configuration and stability of the quarry that these plans were no longer implementable.
