A 'new' island has appeared in the middle of a lake in southeastern Alaska after the landmass lost contact with a melting glacier, NASA satellite images reveal.
The landmass, named Prow Knob, is a small mountain that was formerly surrounded by the Alsek Glacier in Glacier Bay National Park. However, Alsek Glacier has been retreating for decades, slowly separating itself from Prow Knob and leaving a growing freshwater lake in its wake.
