Ancient human grave sites speak volumes to those who listen. These haunting human "time capsules" have been uncovered all over the world. Some even reach a certain level of fame: The Ampato maiden sacrificed on an Andes peak. The Alpine Ice Man, the oldest frozen mummy ever found. England's 9,000-year-old Cheddar Man. Others' stories are known only to the ages, like a cache of elaborately adorned 7,000-year-old mummies unearthed in Chile known as the Chinchorro mummies, and the thousands of Egyptian mummies actually burned as train fuel in the 19th century.
