Errors ranging from 0.10 feet. to no error. <br />TABLE 5-SLOPE STABILITY <br />RELATIVE MOVEMENT <br />NOVEMBER, 1988 TO JULY, 1989 <br />BEAR MINE N0. 3 <br />Point Horizontal Distance Bearing Elevation <br />No. <br />U16 0.18 N03°11'W -0.01 <br />U17 0.21 N35°13'W 0.00 No Change <br />U18 0.27 N26°34'W -0.01 <br />U19 0.34 N29°32'W -0.11 <br />U23 0.06 N09°28'E -0.04 <br />NOTE: Station U19 is a #5 rebar along the access road to the <br />portal. The point was run over by equipment between November, <br />1988 and July, 1989, thus the large drop in elevation. <br />• <br />
