Snow Monkeys!!

This photograph of Japanese macaques relaxing in a hot bath was taken on a winter morning by wildlife photographer and zoologist Heather Angel. The pool is in the Joshinetsu Kogen National Park, Nagano, Japan, in a place known as Hell's valley because of its steep cliffs, dense forests and the boiling water that spurts from the frozen ground. It was built 30 years ago when it was discovered that the monkeys, like us, like to bathe in hot water.

Japanese macaques - also known as snow monkeys - live further north than any other non-human primate. Snow covers the ground in Hell's Valley for four months of the year and temperatures often drop to -20 °C. Thermal pools - both natural and man-made - help the monkeys survive the harsh climate.

So cool, right!?
