Miners made a ground-breaking discovery while excavating permafrost, a frozen layer permanently on or under the Earth’s surface. A mummified baby woolly mammoth that had been frozen was identified by the workers early last week near Yukon’s Klondike region. The rare Mammoth mummy is estimated to be over 30,000 years old, and most likely was frozen during the Ice Age. The baby has been verified to be most likely female, and has retained hair and skin despite dying thousand of years ago. The female baby was named Nun cho ga, which means “big baby animal” in the local native Hän language.
