One day, walking through the Sargamatha National Park, I came across a troop of wild yaks in the heat of heat. It was an amazing show. Males fought on a hillside for a female. They rammed between them and some fell rolling down the slope and then rose and returned to the load. It was surprising to see those huge cows that, in general, seem calm and boring, fighting among them was a unique and memorable occasion.
The yaks release a sticky substance in their own sweat that keeps their inner hair matted, thus offering them a new layer of thermal insulation for their skin. This substance is used in traditional Nepalese medicine.
Yak meat is saved and eaten cured. Do not miss a good yak tortilla in one of the Tibetan or Nepalese villages.
