Measured joint systems on the surface show three dominant trends and are detailed in Table 1 —a <br /> east-west primary trend and two secondary trends at northeast-southwest and northwest- <br /> southeast(Figure 5).No surface joints showed the presence of previous water flows; however, <br /> during the site visit current weather conditions included sporadic light rain. <br /> Table 1.

Additional stereonets are found in Appendix 1. <br /> All three joint set are similar in their filling characteristics and no alteration or clay filings were <br /> observed. All the joint sets appear to be simple fractures with very little dilation occurring at the <br /> time of their formation. All of the joint surfaces appear to be rough and undulating.
