 In 1988, it was noted by the researchers that the graveyard contained an unexpected number of blondes amongst the naturally mummified bodies, as well as oddities in tooth decay amongst the buried; "Of those whose hair was preserved 54% were blondes or redheads, and the percentage grows to 87% when light-brown hair color is added".In 2014, it was revealed that burials seem to be clustered by hair-colour, those with red-hair are in one area, those with blonde hair in another.In 2014, the BYU team claimed that the cemetery contains over a million mummies.
