After a rather cold night (-12ºC inside the tent) we got a glorious day with very bright skies. Ciprian and I went to explore the Rongbuk Glacier up to about 5400 m just before Yak Camp, which seems now more commonly referred to as Japanese Camp. We got a brilliant view on Everest and the flanking peaks. However we had to rush back for the puja ceremony. The ceremony turned into a jolly party with (too) much beer and whiskey for some of the sherpas. After lunch the day turned, due to the unusual warm weather, into a lazy Sunday afternoon.
