During winter, the ice sheet takes on a clear blue/green color.

Around 70% of the fresh water on the Earth is held in this ice sheet.

She could see the ice sheets, and exactly where the tree line started.

In any case, there were no significant ice sheets during this time.

They spend most of their lives in the water rather than on the ice sheets or dry land.

The world was a pretty sight from the ice sheet.

Ice sheets on land, but having the base below sea level.

The face of the ice sheet measured eight feet across.

Although apparently it's only a little piece of the total ice sheet.

But until about 15 million years ago the ice sheet was incomplete.

People who always lived near the poles on the ice cap.

It is also sometimes referred to as an ice cap.

The other, this ice cap, is two miles high and solid.

There's supposed to be water under the surface of the ice cap, but they haven't been able to get to it.

Sites are found close to the ice caps of the time.

It was covered by an ice cap for thousands of years.

You thought that a seal had come to rest on an ice cap!

I'm going to go in fast over the ice cap, try to stay low and approach near sea level.

"No more than a lost city under the ice cap."

Then again, scientists have just discovered how little they know about the ice caps to begin with.

This continental glacier had a profound effect on the surface features of the area over which it moved.

At the end of the last glacial period the continental glaciers were melting to the north.

It generally refers to the extent of continental, rather than alpine, glaciers.

Glacial bodies larger than 50,000 km2 are called ice sheets or continental glaciers.

Approximately 19,000 years ago, the Dells was at the extreme eastern margin of the continental glacier.

There are still some continental glaciers in Greenland and Antarctica.

The reason is that a continental glacier completely disrupts the preglacial drainage system.

Someday, when the continental glacier receded back to its polar home, that highland would be black with forest.

Reminding of the period 250-800 years ago the boulder was carried there by a continental glacier from the south of Sweden.

The movement of these continental glaciers created many now-familiar glacial landforms.
