The towering Himalayas were among the last places on Earth that humanity settled.
Scaling sheer cliff sides, daring scientists hunt for clues as to how ancient people found their way into this forbidding landscape and adapted to survive the high altitude. They discover rock-cut tombs filled with human bones and enigmatic artifacts, including gold masks and Chinese silk dating back thousands of years. They then piece together evidence of strange rituals and beliefs designed to ward off the restless spirits of the dead.
