A nomad family in Eastern Tibet in their summer pastures, which, paradoxically, are often at lower altitude than winter grazing land; in the valleys, the thick winter snow is impenetrable, whereas on the mountain slopes high winds keep the snow thinner, allowing the starving yaks a little meagre grazing. Calving time is in early summer, the only season in which the dri (the female of the yak) can graze enough to feed her young. 1988.
