Jackson tracked and photographed many footprints in the snow, most of which were identifiable. However, there were many large footprints which could not be identified. These flattened footprint-like indentations were attributed to erosion and subsequent widening of the original footprint by wind and particles.

On March 19, 1954, the Daily Mail printed an article which described expedition teams obtaining hair specimens from what was alleged to be a Yeti scalp found in the Pangboche monastery. The hairs were black to dark brown in colour in dim light, and fox red in sunlight. The hair was analysed by Professor Frederic Wood Jones, an expert in human and comparative anatomy.

 

During the study, the hairs were bleached, cut into sections and analysed microscopically. The research consisted of taking microphotographs of the hairs and comparing them with hairs from known animals such as bears and orangutans. Jones concluded that the hairs were not actually from a scalp. He contended that while some animals do have a ridge of hair extending from the pate to the back, no animals have a ridge (as in the Pangboche "scalp") running from the base of the forehead across the pate and ending at the nape of the neck.

 

Jones was unable to pinpoint exactly the animal from which the Pangboche hairs were taken. He was, however, convinced that the hairs were not of a bear or anthropoid ape. He suggested that the hairs were from the shoulder of a coarse-haired hoofed animal.
