The woolly mammoth is the state fossil of Alaska. The mammoth could be up to 12 feet tall, was estimated to weigh around 6 tons, and was covered in long hairs for warmth. Believed to be most closely related to the Steppe elephant of Eastern Asia, this elephant species roamed North America during the most recent Ice Age.
Many fossils of this species have been discovered in Alaska. The last Ice Age created a land bridge connecting Asia and North America, allowing travel for them into what is now Alaska and the Yukon Territory of Canada. Going extinct on the mainland around 10,000 years ago, a small population of woolly mammoths were able to survive on St. Paul Island, Alaska until approximately 5,600 years ago when their supply of fresh water most likely ran out due to the changing climate.
