M ~ <br />Mr. Randy Price 6 J.A.Pendleton <br />May 14, 1986 <br />page 2 <br />On a long range outlook, our plans to deal with these slides fol- <br />lows the philosophy that we are entering our mine through a win- <br />dow in an existing landslide area. This protective window is <br />formed by a resistant outcropping sandstone formation. In <br />general the slides have been moving during wet weather cycles in <br />the north fork valley over the most recent epoch of geologic <br />time. We feel this is a normal landforming process of nature, and <br />we cannot stop it but must learn to work around it. <br />The slide material is to wet to work at this time without bogging <br />down equipment and possibly triggering further movement. From <br />past experience we believe it will be late June or early July <br />before any construction work can begin. we do intend to install <br />some measures of protection during the coming construction <br />season. <br />As was mentioned above we have not finished analyzing our <br />alternatives. When we know specifically what we want to do, we <br />will contact you again. We do feel that after the construction <br />work has been completed, that a cover of a grass seed mix will <br />stabilize the slope. A more extensive re vegetation program would <br />be premature because of the potential for the surface to move <br />again during the next wet spring season. <br />If we can answer any further questions please contact us. <br />Sincerely <br />~1~~ <br />C.G. Hansen <br />Mine Engineer <br />
