that were apparent in the stereonet contour diagrams in Appendix A, but were not above <br /> the statistical cutoff were labeled to investigate their potential to form wedge intersec- <br /> tions. <br /> 3.2.2 Bench 2 Mapping <br /> Limited mapping was performed on Bench 2 to increase the data base and because <br /> the orientations of features exposed there appeared different than in Bench 1. Stereonets <br /> of pole scatter, pole count contours, and pole percent contours for Bench 2 are presented <br /> in Appendix B. <br /> The PATCH program identified two joint pole clusters in the Bench 2 data. Table <br /> 3.2 lists the orientations and ranges. The location of the set poles is shown in Figure 3.5. <br /> Joints in Bench 2 had somewhat lower dip angles than those mapped in Bench 1. <br /> Table 3.2 Joint Set Orientations Identified by PATCH in Bench 2 Data <br /> Set Dip Azimuth Dip Frequency <br /> Designation (degrees) (degrees) of <br /> Occurrence <br /> Mean Range Mean Range <br /> J13 230 ±8.3 71 ±7.9 50% <br /> J12 333 ±24.0 76 ±23.0 21% <br /> 9 <br />
