One person who has spent many vears studying woolly mammoths is the Frech explorer Bernard Buigues. To find the mammoths, Buigues relies on tribes that live in the frozen areas where the creatures once lived. One of these tribes, the Dolgans, live on Sibria's frozen Taimyr Peninsula.The Dolgans knew of many places where frozen woolly mammoths could be found and often used mammoth tusks for tools.
