Puma YumcoThe uplifted plateau of Tibet has risen out of the Asian continent due to piston like tectonic forces from below resulting from the compression as India meets Eurasia in a slow motion collision. Many lakes, some with outlets to the sea and others without dot the plateau including this one snapped last winter as a mosaic from the International Space Station. Puma Yumco measures 31x14km .Sitting at just over 5,000 metres altitude it is low in nutrients and has clear blue water (due to the relative absence of life) , features it shares with many high altitude Himalayan lakes. Changes in colour are due to the depth rather than contents of the water. The white lines are patterns made by frozen blocks of ice as the lake passed through repeated cycles of freezing and fracturing, abetted by the howling winds.LozImage credit: NASA -- source link
