You resolutely trudge along a rocky ridge. It has been cleared of whirling snow by the fierce wind, which bites and blows against your body. The world seems hansformed, and much for the worse. You must find a house or a cabin-people who can help you----or you will die. fu you ponder your fate, you stumble and fall, plunging into a deep crevasse. You black out and later awaken, still shivering, but in a warmer place at least. By the dim amber light, you can see that somehow you have fallen back into one of the chambers in the Cave of Time. A passageway leads to the right, another to the left. Does one lead to the future and one to the past?
