This however is <br />not serious and is not in a dangerous condition. Extensive cracks <br />of four to' six inches wide running parallel with the dsm occur <br /> <br />along both shoulders of the crest showing that the material on <br /> <br />I both i11ppes has settled aYlay'from the center. We oould see no <br /> <br />evidenoe ot the material in the lower faoe ot the dsm having moved. <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />- <br /> <br />down hill or squeezed out as is usually the case where enbanlonents <br /> <br />, <br />, <br />! <br />J <br />, <br />I <br />
