<br />' portals. A smaller earth flow feature which apparently was <br />' not pre-existing developed immediately east of the fan <br />portal. <br />' 2. Slumps - Slumping consisted of shallow (typically 5 to 15 <br />feet thick) features that failed progressively upslope. <br />' Most of the slumping appeared to consist of a series of <br />small "infinite slope" failures. No large, deep circular <br />failures were observed. <br />1 <br />Examination of the interface between ancient slide debris and the <br />' underlying bedrock revealed the base of the slide debris to be <br />' dry. Aowever, a considerable amount of water was observed to be <br />exiting joints in the underlying bedrock under pressure. The <br />' uppermost portion of the slide debris had also become saturated <br />from direct infiltration. Slumping appeared to be in response to <br />t the near surface saturation of a 10 to 20 foot thick layer. At <br />the site of the small flow slide immediately east of the fan <br />1 portal, a sizable stream of water was observed emanating from the <br />1 soil at the base of the scarp approximately 5 feet + below the <br />surface. The flow was estimated to be on the order of 15 to 20 <br />gallons per minute and was not being contributed to by any flows <br />off the surface. These flows exceed what it is felt that the <br />1 silty clays to clayey sands present at that location could <br />' support from normal seepage. Therefore, it is speculated that <br />this flow emanated from a pipe through these clayey soils and was <br />' actually derived from the jointed bedrock underneath. The head <br />scarp of the small flow slide correlates approximately with the <br />1 <br />1 4 <br />
