The landslide is occurring in rocks of the Franciscan Complex. In the area of the roadway it moves on the order of 1.5 to 3.0m/yr. Two inclinometers were installed in the slide to determine the depth to the failure plane(s). One of the inclinometers is located in the roadway, and requres traffic control before it can be read. The coaxial cable of the TDR system was strapped to the outside of this inclinometer's casing to allow for a comparison of the data. The initial data show a spike in the TDR reading at approximately the depth where the inclinometer casing is deflected. This suggest that TDR may be used in place of an inclinometer in some instances
