Meltwaters flow from the Trift glacier in the Swiss alps.
Even Indonesia has glaciers — for now, at least. The ice fields of Puncak Jaya in Papua, Indonesia are, like other glaciers worldwide, shrinking
The Viedma, Agassiz, and Onelli glaciers are visible on this International Space Station photograph of Argentine Patagonia.
Ghosts in a Glacier
A web of cracks in meltwater ice found along the edge of Byrd Glacier in Antarctica. The 85 mile ( 137 kilometers) long glacier flows into the Ross Ice Shelf. About the size of France, the Ross Ice Shelf is the largest ice field in Antartica.

Centuries of Ice
Almost a century ago, Antarctic explorers were awed by the natural ice sculptures they found on the continent. Frank Hurley took this photograph during Ernest Shackleton's "Endurance" Expedition in 1915. The expedition ship became trapped in sea ice during the voyage, forcing the crew to camp on ice for five months. Shackleton and a few crew members eventually took a lifeboat to South Georgia Island for help, a treacherous open-ocean journey that paid off when he was able to rescue all of his men.
Crevasses in the Guyot glacier near Ice Bay, Alaska.
The Aletsch Glacier of Switzerland is the largest in the Alps, but scour marks on the valley reveal that the ice used to extend much higher.
