esker
esker A long, sinuous, steep-sided, narrow-crested ridge which consists of cross-bedded sands and gravels. It is laid down by glacial meltwater either at the retreating edge of an ice sheet, or in an ice-walled tunnel. Subglacially engorged eskers are deposited in subglacial or englacial ice tunnels; to be preserved these tunnels must have been in stagnant ice.
