Thick fur, thick skin, and a small tail and ears are among the cold-weather adaptations that allowed mammoths to thrive until some 12,000 years ago, when they began disappearing from the mainland, although isolated populations persisted until about 4,000 years ago. In June 2022, a 30,000-year-old mummified woolly mammoth calf, with skin and hair intact, was found in the permafrost of Yukon's gold fields - the most complete frozen mammoth specimen found in North America to date. Masterfully crafted by Royal Canadian Mint engravers using a variety of engraving techniques and finishes, which bring depth and texture to this portrait of the famous Ice Age mammal.
