The polar vortex has kept Lake Michigan frozen for the most part of winter. For example, in Chicago, Illinois, temperatures reached -30C (-23F) during the peak of the cold, causing ice shelves to form on the lake – hills formed from waves crashing over existing ice piles. Moving water underneath the ice is pushing the sheets to the surface, shattering them into mesmerizing patterns, visible along South Haven’s pier.

Australian photographer Warren Keelan captures spectacular photos of waves just before and during the moment they break. Fluid dynamics is defined by motion – specifically the motion of substances that do not hold a single form – but one thing I love about wave photography is how crisp and solid water appears when frozen in time. In a way, it feels like a reminder that, even though we classify matter into different states, ultimately those states have a lot in common. (Image credit: W. Keelan; via Colossal)
