Kames are small hills composed of deposits of stratified sands and gravels. Their size
varies from a few metres to conical hills of up to 50 m in height and 400 m in length. They
form by sediment accumulation in supraglacial and englacial cavities (Johnson and
Menzies, 1996) (Figure 5.16). The term kame is also used to describe forms built in a
particular position within or along the glacier. When a channel flows into a lake located on
the ice mass, it carries sediment deposited in the margins; after the ice melt, they result in a
