In reply to Robert Durran:
In 2005 while on a reconnaissance trip for developing paragliding in Bhutan at the bequest of the government, we stumbled across a series of fresh tiger pug marks at an altitude of 4180m. Following the trail we came across a fresh kill and beat a very hasty retreat when a clearly startled tiger vocalised its alarm from a thicket of juniper bushes.
The photos of our GPS showing elevation next to the pug marks was submitted in our report to the Ministry of Agriculture and Forests and we were told at the time that this was the highest recorded evidence to date.
I think large cats at altitude in the Himalaya are not uncommon (a leopard killed my dog while living in Nepal) but seeing them is.
I agree an absolutely stunning photo.
