We are extending the rock wall behind the cabin to prevent erosion. This involves stacking rocks along the bank of the stream to slow the rate of erosion behind the cabin, which is just about 6 feet from the stream. The water level raises to the about 16 inches when it rains heavily so, while we are not overly concerned at this point, we are taking necessary precautions. Still have a way to go, so let us know if you want to help with this wall.
