One person who has spent many years studying woolly mammoths is the French 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 Siberia's frozen Taimyr Peninsula. The Dolgans knew of many places where frozen woolly mammoths could be found and often used mammoth tusks for tools.
