Lake Above the Ocean Source/credit: Vicky Mar What am I looking at? Lake Sørvágsvatn does sit above sea level (about 40 meters), but the cliff is more than twice as high as the lake. This creates an optical illusion of forced perspective. Our brains have difficulty judging the height from this angle.
