The largest glacier in the world is the Lambert-Fisher Glacier in Antarctica. At 400 kilometers (250 miles) long, and up to 100 kilometers (60 miles) wide, this ice stream alone drains about 8 percent of the Antarctic Ice Sheet. Antarctic ice is up to 4.7 kilometers (3 miles) thick in some areas.
Which is the second largest glacier in the world?

Which is the largest glacier in Europe?
Situated in Vestland county in Fjord Norway, Jostedalsbreen is the largest glacier in continental Europe, covering 487 square kilometres with ice up to 600 metres thick.
Where is the largest glacier in the US located?
The largest glacier in the United States is the Bering Glacier, near Cordova, Alaska. With its associated icefield feeders it is 203 km (126 miles) long and covers an area of more than 5,000 square kilometers (1,900 square miles).
Where is the oldest glacier?
How old is glacier ice?
- The age of the oldest glacier ice in Antarctica may approach 1,000,000 years old.
- The age of the oldest glacier ice in Greenland is more than 100,000 years old.
- The age of the oldest Alaskan glacier ice ever recovered (from a basin between Mt. Bona and Mt. Churchill) is about 30,000 years old.
Which country has no glaciers?
Without glaciers, one resident quipped, Iceland is “just land.”
Why are glaciers so blue?
Glacier ice is blue because the red (long wavelengths) part of white light is absorbed by ice and the blue (short wavelengths) light is transmitted and scattered. The longer the path light travels in ice, the more blue it appears.
Which is the slowest glacier in the world?
The slowest glaciers in the world are cold-based glaciers, which often only move very slowly. These glaciers are frozen to their bed and have little basal sliding.
Which is the smallest glacier in the world?
Gem Glacier is the smallest named glacier in Glacier National Park (U.S.).

Which is the longest Alpine glacier on earth?
At 62 kilometres (39 mi) in length, its Baltoro Glacier is one of the world’s longest alpine glaciers. Aerial view of a glacier in Chugach State Park, Alaska, United States.
What US state has the most glaciers?
Most U.S. glaciers are in Alaska; others can be found in Washington, Oregon, California, Montana, Wyoming, Colorado, and Nevada (Wheeler Peak Glacier in Great Basin National Park).
Which US National Park has the most glaciers?
The largest national park in the United States, Wrangell St. Elias National Park and Preserve in Alaska spans an impressive 13.2 million acres. Within this vast landscape lies our nation’s largest glacial system. It encompasses approximately 5,000 square miles and contains some of the largest glaciers in the world.
Why are glaciers disappearing?
Specifically, since the industrial revolution, carbon dioxide and other greenhouse gas emissions have raised temperatures, even higher in the poles, and as a result, glaciers are rapidly melting, calving off into the sea and retreating on land.
How old is the oldest ice on Earth?
To get that kind of neatly layered ice sample, scientists need to drill straight down through the thick Antarctic ice sheet. So far, the oldest ice collected that way goes back 800,000 years. Now, several groups from around the world want to drill down to ice that’s even older, more than 1.5 million years old.
Where is the youngest ice found?
They are essentially frozen time capsules that allow scientists to reconstruct climate far into the past. Layers in ice cores correspond to years and seasons, with the youngest ice at the top and the oldest ice at the bottom of the core.
How long does a glacier last?
Then, as large glaciers retreat, the underlying ground surface is typically abraded of most materials, leaving only scars and debris on the underlying bedrock surface. Over the past 60 to 100 years, glaciers worldwide have tended to retreat.
