Also mysteriously avoiding the melting trend is the Perito Moreno glacier. Located in a national park in Argentina, it does more than just defy global warming. A massive arch grows for 2–4 years before collapsing into the water below. Then, from white and blue ice, a new bridge starts growing and the whole cycle repeats.
The moment the structure falls is such a spectacle that tourists hold vigils in March just to witness it. The reason why it keeps falling down is due to an interesting process.
The Perito Moreno glacier does experience some melting, which then drains into the lake below the arch. As the water level rises, the lake hollows out the glacier. This tunnel weakens the structure’s integrity until it eventually disintegrates.
From storybook snowcapped mountains to the poles, Earth’s cold spots make for an interesting experience. Ski antics and monster sightings aside, ice fields can produce things that scientists have never seen before, clues about history, and even far-reaching disasters that are born in the Arctic.
Tourists travel to remote places to witness fantastic events, while icebergs and shelves behave in ways that scientists cannot explain. But the frozen depths can also hold some of the most terrifying discoveries and disappearances in the natural world.
