0 -604 0 -602 -602 -604 Narrow Gulley You are clambering through a narrow rocky gulley, the floor of which is sloping at an angle of almost 45 degrees. Shale and loose stone make the gulley treacherous, as your feet send bits of rock tumbling down into the valley below. You can clamber up the gulley towards a turning or down it towards the valley floor.
