Taylor Esker

The Taylor Esker is a glacial landform in Victoria Land, Antarctica. An esker is usually a winding ridge of sand and gravel deposited by meltwater flowing through or beneath glacial ice.

No, Taylor Esker is a sedimentary ridge left by former meltwater channels rather than a moving body of ice. Its location near the Taylor Glacier region makes it useful for interpreting past glacial conditions.

The sediments and shape of an esker preserve clues about how meltwater moved beneath or beside an ice sheet. In Victoria Land, those clues help reconstruct the glacial history of Antarctica's Dry Valleys and surrounding ice systems.

An esker is mainly formed from water-sorted sand and gravel deposited by subglacial streams. A moraine is a ridge or pile of sediment carried and left by glacial ice, often with a more mixed and unsorted texture.
