S2 E13:
Gold is the most irresistible metal on the planet. This precious metal started life in a super nova which scattered far and wide throughout the Earth's rocks. Huge pockets of gold are found in a handful of places throughout the world. Scientists investigating where gold is concentrated in the US have discovered nuggets dumped in California's streams and gold-quartz veins buried beneath the Sierra Nevada mountains.
