The data demonstrate that <br />the Blue Ribbon portal bench remains structurally stable beneath its surficial <br />cover. Continued monitoring of last summer's repaired surficial failure <br />should determine whether the upper surficial zone has been stabilized. <br />• <br />cc: Susan Mowry <br /> <br />
