Thinhorn sheep
These sheep are about 1.5 m high and can weigh up to 110 kg.  The female sheep have small horns but the male sheep have larger horns that twist more as they get older.  The horns are tan in color.  The wool of Dall's sheep is almost pure white.  The wool of the stone sheep is almost all black. Stone sheep's horns do not flare out as much and are lighter in color.
