Leftover coffee


Blue ice

Pressurized ice, not privy to direct sunlight, sparkles a luminous blue deep in Breiðamerkurjökull ice cave. The cave is part of Iceland’s Vatnajökull Glacier, one of Europe’s largest ice caps, which began forming 2,500 years ago and sits atop several volcanoes. As a result, ebony often streaks the azure interiors.
