Snow falls over a black landscape dotted with golden boulders. A woolly mammoth skeleton appears and sinks in the ground. Ruins are trapped under layers of sediment and then excavated with a crane. A man photographs the ruins, and another set arrow heads out on a graph. Title reads 1936, and then cuts to living woolly mammoths. They all gather around a glacier, and then the camera pulls back to show North America and a land bridge with Asia.
