The data demonstrate that the Blue Ribbon portal bench remains <br />structurally stable beneath its surficial cover. Continued monitoring of last <br />summer's repaired surficial failure should determine whether the upper <br />surficial zone has been stabilized. <br />If you have any questions, please do not hesitate to contact me. <br />Sincerely, <br />4/<~~ <br />Matthew S.
