Known as Mirror Lake, Lake Matheson, near the Fox Glacier in South Westland, New Zealand, is famous for its reflected views of Aoraki/Mount Cook and Mount Tasman. The water of Lake Matheson is dark brown, so on a calm day they create the ideal reflective surface. The colour is caused by natural leaching of organic matter from the surrounding native forest floor. By a happy coincidence, the mountains to the east are perfectly positioned to reflect in the lake.
