The survey was <br />performed April 1, 1994. <br />The survey results indicate that there has been very little <br />movement of the monuments, since the monuments were installed in <br />1985, and since the last survey. Not withstanding the previously <br />observed and documented episodes of mass movement, no additional <br />Division concerns have resulted from review of this data. <br />Please let me know if you have any questions. <br />ly, <br />Christine E.
