Iceblink

Ice Islands with ice blink, watercolour by Georg Forster, made 1773 during the second voyage of James Cook

Iceblink is a white light seen near the horizon, especially on the underside of low clouds,[1] resulting from reflection of light off an ice field immediately beyond. The iceblink was used by both the Inuit and explorers looking for the Northwest Passage to help them navigate safely.[1]
