Glacier of the White Worm

The Glacier of the White Worm was a glacier situated high in the Earthspur Mountains in northeast Faerûn, lying between the Moonsea, Damara, Impiltur, and the Vast.

Geography
The glacier was a great river of ice that weaved between the tallest mountains of the Earthspurs. On the north-west side, it flowed over a high cliff and spilled into the Moonsea. In the east, it flowed into Lake Icemelt, which lay in the mountains between Damara and Impiltur.

As old histories and maps recorded, it was once a part of the Great Glacier, the much larger icesheet that lay some 400 miles (640 kilometers) to the north. Curiously, the Glacier of the White Worm survived much farther south than its altitude allowed, suggesting that magic or some other force might be involved.

History
Old maps, such as those made in Year of Oaths Forsaken, −626 DR, showed the Glacier of the White Worm joined to the greater icesheet of the Great Glacier.

By the Year of the Spreading Spring, 1038 DR, the Great Glacier had retreated from the land of Damara, This led to the separation of the Glacier of the White Worm.
