Ice on the Move

This image, acquired by the Operational Land Imager (OLI) on Landsat 8, shows Hubbard Glacier, located on the border of Alaska and the Yukon, on July 22, 2014. Before it reaches the sea, Hubbard is joined by the Valerie Glacier to the west, which, through forward surges of its own ice, has contributed to the advance of the ice flow that experts believe will eventually dam the Russell Fjord from Disenchantment Bay waters.
