Cornwall Glacier () is a
glacier
A glacier (; or ) is a persistent body of dense ice, a form of rock, that is constantly moving downhill under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires ...

It appears to be static.
The valleys on either side probably do not contribute ice.

The valleys of the Gordon and Cornwall glaciers may reflect an underlying fault zone, and have been treated as a divide between the western and eastern portions of the Shackleton Range.
