Yaks are everywhere along the trekking routes in the Himalayas. They're used to transport everything from lumber to cases of beer. I was usually so preoccupied with not getting trappled or pushed off the trail that I didn't get any decent photos of any. At one point along the path, I turned to look back at the scenery and saw this young yak staring up into the sky framed by the prayer flags as if it were praying and snapped a quick shot. It has become one of my favorite memories of that adventure.
