The children on Llullaillaco were very young when they died. Scientists think that the boy and two girls were between six and fifteen years old. They had been frozen on the summit of llullailaco for over 500 years. Reinhard couldn't believe how well the mummies had been preserved. They looked like they had been duried only a short time before. The mummies were carefully removed and carrid down the mountain. Since then reinhard has had the chance to study them and has even found a living relative of one of the girls.
