In ocher seations~stabillty of tllc downslope is maintained. <br />hlr, Bob Asher, the Bluc Ribbon Mine Superi.ntcndcnt prior to lJestern purchasing <br />the mine, also concludes Chc lack of stability in the bank is related to <br />spring run-off. <br />Location <br />~~ <br />A copy oC an aorinl photol;raph will serve to demonstraCC this.
