"Sweet Creek" by Lee Lynch (Bold Strokes Books) at Lake Pukaki with Mt Cook/Aoraki (the highest mountain in NZ) in the background. (Yes, the lake really is that turquoise colour--it's not me fiddling around with Photoshop. The lake is fed from glaciers, and it's the way light reflects off the finely ground "glacier flour" suspended in the water that gives it the amazing colour.)
