Journey by Stephen Clark  
    to Ridgetown floatfloatfloat

You come to a stretch of river where the sides are lined with sheer cliff-faces. No sun filters down to this deep ravine. It's so cold down here, you think you'd better get out of the water or you'll die of hypothermia. But there seems to be no way out - the rocks are too high and smooth. The river moves painfully slowly. You swim over to the cliff-face and try to climb out of the water, but it's no good. You're too tired and cold. Eventually you can go no further - you fall back into the water and drown.
