A huge iceberg called A-68 calved from the Antarctic Peninsula's Larsen C ice shelf, July 12, 2017. Three years on, it is in open waters near the South Orkney Islands in the South Atlantic Ocean ? about 1050 km from its birthplace. The berg has already lost two chunks of ice, which were big enough to be given names: A-68B and A68C. (Photo/ICphoto)
