NASA satellites spot brand-new island in Alaska formed by melting glacier
Prow Knob, a 2-square-mile landmass, became an island after Alsek Glacier retreated over 3 miles since 1984, doubling Alsek Lake's size, NASA confirmed.
- A retreating glacier revealed a new island in Alaska this summer, surrounded by Alsek Lake.
- Pelto anticipated that the Alsek Glacier would detach from the land mass known as Prow Knob, leading to the formation of this island.
- Prow Knob measures about 2 square miles and has a peak of over 1,000 feet.
- Alsek Lake has grown over time as glaciers continue to retreat.

The Alsek glacier in the southeast of Alaska melts at a high speed – and creates islands where land masses used to be. Nevertheless, the fact that the water level does not rise off the shore of the state is due to a little-known phenomenon.
The retreat of a glacier led a piece of land to be completely surrounded by a lake
Recent space images taken by NASA's Landsat have revealed the formation of a new island off the coast of Alaska, as a result of the melting of an ice river, separating a small mountain from land. Compared to 5 July 1984, the images showed that the small mountain known as Pro Nob was separated from the land after the Elsik glacier retreated for more than 5 kilometres, creating a large lake around the new island of about 5 square kilometres.
