Standing at the base of Mount Fitz Roy in the Patagonia Ice Fields, there are two very distinctly different lakes. The one to the left is a very vibrant and bright emerald green color, while the one to the right is a very deep and bright electric blue. The reason for this anomaly is due to the different types of sediment that was collected by the glacier advancing and receding. The colors are kept separate due to the big rocky divide in the center of the photo.
