Hi All,
In May of 2004, I encountered two snow leopards hunting a dzo (part cow part yak) while climbing Stok Kangri Glacier in Ladakh, India. Amazingly, the dzo was a healthy, full-grown beast weighing at least six times as much as the leopards. I put together a very short documentary which includes the footage. It can be viewed at:
