Yaks (Bos grunniens and Bos mutus) sightings are common in Himalaya. For many generations, inhabitants of high-altitude regions; Karakorum, Tibet, Mustang, Everest, have been using Yaks’ Milk for sustenance (few other using its meat for meal).
The experts suggest, yaks are more closely related to American Bison than to the other members of its designated genus, i.e. Cattles. Some Yaks in the wild could weigh a ton, making it a huge and a dangerous animal.
People in Northern Nepal have been using yaks to carry loads; salt and other edible products, for trade since primitive times. Eric Valli’s film “Caravan” shows how they’ve been used for the variety of transports.
The boom in tourism of Khumbu valley and the heavy influx of trekkers motivated many Sherpa guides and porters to employ domesticated Yaks in great numbers to carry heavy loads up to the Everest base camp.
One can enjoy observing “Beasts of Burden” in one of the Everest treks.
