The Boyd Glacier is located in Antarctica. It flows west-northwest for about 45 miles between Bailey Ridge and Mount Douglass.
It forms a ridge called moraine
moraine
An extensive pile of till (loose debris & rocks) called an end moraine can build up at the front of the glacier and is typically crescent shaped. Two kinds of end moraines are recognized: terminal and recessional moraines. A terminal moraine is the ridge of till that marks the farthest advance of the glacier before it started to recede. A recessional moraine is one that develops at the front of the receding glacier; a series of recessional moraines mark the path of a retreating glacier.
Moraine are the rock and soil debris deposited on the surface of a glacier by avalanches and landslips. Those at the edges (the first formed) are Lateral moraine. Those at the terminus of the glacier are Terminal moraine. Where two glaciers join, then their lateral moraines join to become a Medial moraine, i.e. 'middle'. The moraine overburden lodged towards the head of a glacier, tends to slip down the schrunds and is a major erosive component in the abrasive action. Where the glacier travels over a step in its bed, an ice-fall is created, marked by a crevasse jumble, and into this much other moraine is embedded into the traveling glacier. It is remarkable to realize that most of the cross-section of the U-shaped of a glacier's valley has been removed by abrasion - converted into rock flour.
The answer is a serac.
This is known as the terminal moraine.
"Eskir"EskerA glacial ridge could be defined as several things:- An arête: a steep ridge formed by glaciers.- Corries: formed through glacier action.- Eskir/esker: a ridge of sand and gravel deposited by glacial movement.- Serac: a block of ice formed by intersecting crevasses on a glacier
