Some fantastic pictures at the Big Picture page on the Boston Globe website. This is a neverending source of amazing photography and I highly recommend you subscribe to the page via a feed reader such as Google Reader.
The pictures this time are about a prayer festival in Tibet. Tibet is often referred to as the ‘roof of the world’ as it is the highest region on earth with an average elevation of 4,900 metres. It is technically part of China although the Tibetans for a long time have wanted to return it to being an independent Buddhist Kingdom with the Dalai Lama as head of state.
