When a glacier's size shrinks below a critical point, its flow stops and it becomes stationary. Meanwhile, meltwater within and beneath the ice leaves [[Stratigraphy|stratified]] alluvial deposits. These deposits, in the forms of columns, [[Terrace (geology)|terraces]] and clusters, remain after the glacier melts and are known as "[[glacial deposits]]". Glacial deposits that take the shape of hills or mounds are called ''[[kame]]s''. Some kames form when meltwater deposits sediments through openings in the interior of the ice. Others are produced by fans or [[river delta|deltas]] created by meltwater. When the glacial ice occupies a valley, it can form terraces or kames along the sides of the valley. Long, sinuous glacial deposits are called ''[[esker]]s''. Eskers are composed of sand and gravel that was deposited by meltwater streams that flowed through ice tunnels within or beneath a glacier. They remain after the ice melts,<ref name=dkp/> with heights exceeding 100&nbsp;meters and lengths of as long as 100&nbsp;km.
