Quiescent phase

The period in which a surge-type glacier is slow-moving or stagnant. This period is typically decades long in contrast to the surge phase that may last only a few months or years.

Iceberg Glacier, Axel Heiberg Island. The glacier surface is usually crevasse-free and characterised by the development of deep stream channels and potholes. These features are typical of surge-type glaciers in their quiescent state. Aerial photo J. Alean, 1977.
