Sometimes when you’re in the right place at the right time, you’ll be lucky enough to capture incredible footage of a glacier calving, like the luck Leandro Borja enjoyed when he shot this video in Argentina’s Patagonia region. But sheets of ice breaking off a glacier is one thing, a huge ice bridge collapsing and creating a huge wave of water is quite another. Watch the colossal collapse of an ice bridge that is connected to the Perito Moreno glacier, one of the largest in Patagonia:

From Our Amazing Planets:

Perito Moreno differs from other glaciers in that it periodically cuts off the major southern arm of Lake Argentino, known as Brazo Rico, by forming a natural dam and preventing water from transferring between the two bodies of water.

“This glacier is somewhat unique in that its path takes it across an arm of a large lake,” NASA scientist Jim Foster told Our Amazing Planet. [...] “Most glaciers don’t have such trajectories, so bridging and tunneling, at least at this scale, is rather rare.”

Nature provides some incredible sights. You just got to be there at the right time.
