Don’t look down – it’s a long way to the bottom of that cliff! Big Horn Sheep are famous for their ability to climb high, steep, rocky mountain areas.  Their name is obvious – the male’s horns can weigh up to 30 pounds (14 kilograms) or 10 percent of the overall body weight.  The horns can be used as weapons when the males fight. They charge each other at a speed up to 32 km per hour and crash head to head. Because their skulls are thick, this rarely causes serious injury!   Purrs, Gulliver
