Photo by @paleyphoto (Matthieu Paley) | Beast of nature: a Bactrian camel sits out a snow storm in Afghanistan’s Pamir mountains. Bactrian camels are native to the steppes of Central Asia where they have been used as pack animals along the Silk Road since ancient times. They have an incredible tolerance for cold, high altitude or drought - they can go without water for months at a time, and then drink up to 57 liters at once. Bactrian camels belong to a fairly small group of animals that regularly eat snow to provide their water needs. The latent heat of snow and ice is enormous compared with the heat capacity of water, demanding a large sacrifice in heat energy and forcing animals to eat only small amounts at a time. Up at 14.000 feet that day (4250 meters), I couldn’t feel my face anymore, but this guy was just chilling… For more interesting encounters, please visit @paleyphoto - on assignment for @ナショナルジオグラフィック #silkroad #centralasia #bactriancamel #camel #snowstorm #mountainstorm #highaltitudeanimal #beastofnature #pamirmountains
