The ridge abruptly rises near the lake’s edge. It is more than a half mile long and hundreds of feet high. The flat ground extending from its base (undoubtedly a flood plain from more remote times) renders the promontory all the more stunning. Walls and towers cling to the rock like barnacles. I wonder why these man-made constructions were thought necessary. The plunge to the flat is so vertical, so awful, that the ridge ably protects itself.
