RESPONSE: Because of the lack of available data, and the apparent <br />impossibility of generating data adequate to the task, we do not know at <br />this point whether it will be possible to describe and charaMerize the <br />structural geology of the slide area to a reasonable degree of certainty. <br />We will provide a description of the possible structural geology of the <br />slide area, based on the limited data available, with our Phase I report. <br />Because it is difficult to describe to a reasonable degree of certainty the <br />structural geology of the slide area, we are currently uncertain whether it <br />will be possible to reach a conclusion concerning the effect the actual <br />structural geology may have had on the landslide. We are continuing <br />our analysis of this issue, and will include a statement of our current <br />impressions in our Phase II report <br />The location and extent of the "scoria" outcrop neaz the southwest comer of the landslide. <br />Please determine whether this geologic feature contributed to the landslide. <br />RESPONSE: We will provide a map showing the location of the "scoria" <br />outcrop by no later than December 8, 2006. At the present time we do <br />not believe it possible to determine to a reasonable degree of certainty <br />whether this outcrop had any effect on the landslide. Our current <br />impression is that it did not. We will include any update of our thinking <br />in this regard in our Phase II report. <br />The sheaz strength, cohesion, and angle of friction of the materials in the failure <br />surface/zone. <br />RESPONSE: We will include in our Phase I report our initial <br />impression of the location of the failure surface/zone and of the shear <br />strength, cohesion and angle of friction of that zone, based on the limited <br />bore hole data available. We will include an update of our thinking on <br />this topic in our Phase II report <br />The amount and weight of materials that contributed to the driving forces of the slide. <br />RESPONSE: We do not know at this point whether it will be possible to <br />determine the "driving forces" of the landslide, given currently available <br />data. We also do not know at this point whether it will be possible to <br />defmitively characterize the volume or mass of material involved in the <br />landslide or to estimate quantitatively its weight and volume. Even if <br />that proves to be possible, we do not know whether it will be possible to <br />determine to a reasonable degree of certainty whether this mass or <br />volume contributed to the driving forces of the landslide. We will <br />include our current impressions on these topics in Phase II of our report, <br />and provide then our opinion on the feasibility of reaching a definitive <br />conclusion on them. <br />The total forces that drove the slide, the resistive forces from side or boundary conditions, <br />and the forces that arrested the slide. <br />
