There is an uncommonly harsh beauty to the Tibetan landscape. Its nakedness makes it seem incapable of deception, but under its calm deportment it conceals winds so brutal that yaks are known to die while their jaws are in masticating bliss. On hot summer days the sun licks up the rain within minutes. No puddles are formed; no moisture lingers in the air. It is only the droplets on tiny leaves of the baby turnip plant that betray rain.
