Struggle as she would, she could not free herself. High up, over wood and stream, the giant carried her; and then he flew swiftly away with her, toward his home in the chill Northland; and, when morning came, poor Idun found herself in an ice-walled castle in the cheerless country of the giants.

Some of these were deposited behind the ice front in ice-walled channels, some at the edge of the glaciers by issuing streams, and others were spread to long distances in front of the ice edge by glacial waters as they flowed away. ESKERS are narrow, winding ridges of stratified sand and gravel whose general course lies parallel with the movement of the glacier.
Sometimes they are so covered up that persons can cross in safety, at other times the snow 'bridge' gives way under their weight and they are precipitated into the crevasse itself, an ice-walled chasm." "Then we may never get the professor out," cried Billy in dismay. "How deep is that crevasse likely to be?" "Perhaps only ten or twenty feet. Perhaps several hundred," was the alarming reply.
These ridges, though evidently laid by running water, do not follow lines of continuous descent, but may be found to cross river valleys and ascend their sides. Hence the streams by which eskers were laid did not flow unconfined upon the surface of the ground. We may infer that eskers were deposited in the tunnels and ice-walled gorges of glacial streams before they issued from the ice front.
