Because the <br /> extent of mapping is not defined in the previous reports (AAI, 1999; and SRK, 2007), and no <br /> instrumentation (i.e., inclinometers) is located with these zones, the timing and condition of <br /> movement in these areas is uncertain. <br /> Legend <br /> Inclinometer <br /> Tension cracks and scarps <br /> as mapped by AAI(1999) <br /> Approximate locaiton of scarp 4l <br /> mapped by BGC but not <br /> included in AAI(1999) T` <br /> 0 Area of ground deformation ' <br /> mapped by BGC but not <br /> included in AAI(1999) <br /> Slope Failure <br /> ® East Wall(since 1979) 1 <br /> ti <br /> - East wall 10,500 ft(1980) ) j <br /> South Wall(1983) <br /> - Northeast Corner(1983) <br /> ® Northwest Corner(1983) <br /> South Wall(since 1996) <br /> South Pit East Wall(since 2005) <br /> J/�l\ 111 <br /> North Pit <br /> South <br /> Pit <br /> 1. 1 <br /> Note: Approximate location of scarps and areas of ground movement mapped by BGC, but not included in the AAI (1999)map of <br /> tension cracks and scarps(Yellow polygons and yellow dashed line).Tension cracks and scarps mapped by AAI(1999)are <br /> shown as black lines,and the location of active and previously active slope movement is shown. <br /> Figure 3-16.Approximate location of scarps and areas of ground movement. <br /> 3.4.3.2.
