A new image of the San Quintín glacier of Chile shows less ice than in previous years. Like many glaciers in the Andes, this river of ice is retreating rapidly.
Glaciers are essentially giant rivers of ice that are formed over eons as fallen snow is compressed into layers of ice. Glaciers are found on about 10 percent of Earth's land area, with most of them found in the Arctic and Antarctica regions, but some occurring high up on mountains, even in tropical areas. Glacial ice makes up the ice sheets that cover Antarctica and Greenland, with glaciers flowing out to sea, where their ends float on the water as ice shelves. Eventually pieces of the ice shelves break off, or calve, to form icebergs. The movement of glaciers scours the underlying rock, and a glacier's movement can be affected by climate change, with worries that global warming could cause substantial glacial melt and impact global sea levels.

A bizarre June snowstorm hit Glacier National Park in Montana and parts of Utah and Idaho this week, leaving many residents and visitors in the northern Rockies wondering what season it is.
A frozen river in the Arctic desert recently led scientists to a remarkable find: a freshwater spring gushing from a deep gully on Canada's Ellesmere Island.
As the glaciers melted about 15,000 years ago, warmer weather and ice-free conditions allowed king penguins to colonize the string of islands north of Antarctica, a new genetic study has found.
Volcanoes under the ice in Antarctica appear to contribute to the melting of glaciers, potentially lubricating the overlying ice and contributing to the glacier's speed of flow.
Global sea level could rise between 10 to 13 feet if a relatively small mass of ice currently corking an Antarctic Ice Sheet were to melt with warming sea water.
An amazing landscape left behind by melting ice sheets offers clues to the future of Greenland's disappearing glaciers, a new study suggests.
The last glaciers in the United Kingdom melted centuries ago, not 11,500 years has had been believed, new research finds. Scotland's Cairngorm Mountains hosted glaciers in the Little Ice Age.
A 54-year-old message in a bottle was found on Ward Hunt Island, a remote island in the northernmost part of the Canadian Arctic.
A big chill 2 million years ago bred glaciers that scoured mountains across the planet, pouring trillions of tons of mud into the oceans.
