Moving to high altitude

We are beginning to climb to very high altitude, so hopefully my luck will hold and I will continue to feel OK. We are going to cross 2 high passes at 16,000ft an follow the banks of Yamdrok Tso Lake for more than 40 miles. The scenery is spectacular, and I am seeing more mountains than I have ever seen in my life, but we are still a long way from Everest.

The piles of stones on the beach are made by people adding a stone for a prayer.
