Bárbara Hernández Huerta, a winter swimmer from Chile who won two gold medals at the 2016 Winter World Swimming Championships in Tyumen (Russia), was swimming along the O’Higgins Glacier in Chile when it started calving.

The Sirena De Hielo swam while the glacier was calving in Bernardo O’Higgins National Park and her ice calving swim was captured on film.
