Sometime during the period of December 2,2007 and December 5,2007 Mother Nature again demonstrated her awesome power when a massive wall of rock, earth and debris slid down the side of Mt Orrock into Chehalis Lake. The resulting tsunami washed across the lake in a wall of water which is estimated to have been 10 meters or more high. As this wall of water struck the shoreline on the opposite side of the lake, it destroyed all vegetation in it's path, ripping out huge trees by their roots, drawing them back into the lake as it ricochets back across the lake to continue its devastation of the shoreline on the side of the lake where the slide occurred. How many times this wave went back and forth across the less than one km wide lake (measured directly across from the slide) can only be guessed. This wave also traveled the 7 km length of the lake to it's southern end, ravaging the shoreline along the way.
