This rare Himalayan mountain cat is seldom seen, even by locals who live nearby. In this remote part of the world, this animal is almost mythical.
By chance, Planet Earth crews locate a snow leopard. Then, they get what's been called "the Holy Grail of filmmaking."
As the cameras roll, the female snow leopard begins hunting a mountain goat along the treacherous slopes. Large paws give her a firm grip, and a long tail helps her balance. When snow begins to fall, her chances improve. Snow offers camouflage and dampens the sound of her approach.
After an unsuccessful attempt, she finally makes a kill far from her den of cubs. Thankfully, an adult snow leopard can drag prey three times its own size up the steep slopes.
