Another thought on this is how do they know the pollen surrounding the body wasn’t transported to the site by the hikers that found the body or by the researchers visiting the site? It was reported in 1991 that after the hikers notified the authorities, it was several weeks or months before they investigated, but word spread and souvenir hunters visited the site and took several artifacts before the site was secured. Those people could hàve transported moss and pollen there as well.
Good point.
Is there any way to date the pollen?... To be able to say that such and such pollen is “mummified,” while another sample is fresh?
