The turquoise water of Lake Pukaki owes its color to rock flour — glacial silt so fine it remains suspended, scattering blue and green wavelengths back toward the surface in a color that looks invented. Aoraki/Mount Cook rises at the head of the lake, the highest peak in the Southern Alps, its permanent snowfields feeding the Tasman and Hooker glaciers whose meltwater created this color. This eight-image medium format panorama was assembled to capture the full scale of the lake corridor, from the gravel bars of the near shore to the summit snowfields thirty kilometers distant. The light was the flat, clean light of early morning on the South Island, before the Canterbury winds arrived.
