 The wool.
  Wool of mammoths is frequently found till now in areas of frozen ground in Yakutia. Therefore scientist enough succeeded in learning it’s structure. The wool of a mammoth consists of two parts: a soft light brown undercoat of hairs with length 5-15 centimetres and a long covering hairs. A covering hairs are more thicker and rigid, than undercoat. They hanged down on each side and from back as meter length tresses of a rigid fulvous-brown and black hairs. Under a belly they were lowered almost up to ground and organized original "skirt". From afar it was possible to accept a mammoth for a driven woolen mountain.
